claim 1unconfirmedUS
FDA CPG Sec. 655.100 ("Devices Used in Animals") states that devices intended solely for animal use are not subject to premarket notification or premarket approval
jurisdiction: US — confidence: unconfirmed — source: no connector in this repo serves FDA Compliance Policy Guide text, so nothing was queried against this proposition. Probe runs of 510k "veterinary negative pressure wound therapy" --jurisdiction US (detail: "No 510(k) record found") and `classification…the full check --device-name "veterinary negative pressure wound therapy" --jurisdiction US (detail: "No classification record found") returned nothing, which is the expected result for an animal device and is **silence, not confirmation** — an absent clearance record cannot establish a regulatory policy, and is explicitly *not* recorded here as support. Settled only by a human reading CPG Sec. 655.100 (CPG 7125.35) in full from the FDA Compliance Policy Guides manual. **Re-verification pass 2026-08-23 — the "permanently unanswerable" verdict was wrong, and the tag stays unconfirmed for a narrower reason than before.** The regulation (eCFR) connector is now available and was run against the *substance* of this claim, which is separable from its *attribution*: (i) regulation 807.81 --title 21 --expect "human use" --jurisdiction US → status verified, source_ref **eCFR versioner title-21, issue 2026-08-19, section=807.81** — 21 CFR 807.81(a) imposes the premarket notification duty only on "each person who is **required to register his establishment pursuant to § 807.20**" and only as to "a device **intended for human use**"; (ii) regulation 814.1 --title 21 --expect "human use" --jurisdiction US → status verified, source_ref **eCFR versioner title-21, issue 2026-08-19, section=814.1** — 21 CFR 814.1(a) provides PMA procedures "for medical devices **intended for human use**"; (iii) 21 CFR 807.65(b) (quoted in full on the next claim line) exempts "a manufacturer of devices to be used **solely for veterinary purposes**" from the § 807.20 registration on which 807.81(a) is predicated. **Why this is still unconfirmed and not verified:** the claim as written is an *attribution* claim — it asserts what CPG Sec. 655.100 **states**. A Compliance Policy Guide is not codified in the CFR, the eCFR connector serves regulation text only, and nothing in this repo reaches CPG, guidance, or enforcement text; so the attribution was never checked and cannot be. Upgrading on the CFR reads would be citing a different document than the claim names. **A regulation 655.100 probe was deliberately NOT run:** "CPG Sec. 655.100" is not a CFR citation, the connector treats a nonexistent section as refuted, and a category-error query would have manufactured a refuted` result about a section this claim never referenced. Action for the Generator/Scorer: restate this as two CFR-cited sub-claims — "21 CFR 807.81(a) conditions premarket notification on a device intended for human use and on a § 807.20 registration duty" and "21 CFR 814.1(a) scopes PMA to devices intended for human use" — both of which verify today against the source_refs above. The residue a human must still read the CPG for is FDA's stated enforcement policy toward animal devices, which is an interpretation question the regulation text does not answer.
claim 2verifiedUS
Manufacturers of devices used exclusively in veterinary medicine are not required to register establishments or list devices with FDA CVM
jurisdiction: US — confidence: verified — source: python3 -m connectors regulation 807.65 --title 21 --expect "veterinary" --jurisdiction US → status verified, source_ref eCFR versioner title-21, issue 2026-08-19, section=807.65, which states: "§ 807.65 Exemptions for device establishments. The following…the full check classes of persons are exempt from registration in accordance with § 807.20 ... (b) A manufacturer of devices to be used solely for veterinary purposes." The listing half is carried by python3 -m connectors regulation 807.20 --title 21 --expect "human use" --jurisdiction US → status verified, source_ref eCFR versioner title-21, issue 2026-08-19, section=807.20: "§ 807.20 Who must register and submit a device list? (a) An owner or operator of an establishment not exempt under section 510(g) of the Federal Food, Drug, and Cosmetic Act or subpart D of this part who is engaged in the manufacture ... of a device intended for human use shall register and submit listing information ..." — the registration-and-listing duty attaches to human-use devices and expressly carves out the § 510(g) exemptions that 807.65 enumerates. This claim's earlier tag rested on a tool gap that no longer exists (the previous pass predated the regulation connector and recorded the claim as "permanently unanswerable"; it is not). Two scope limits on the verification, both of which a later reader needs: (a) it is verified from the regulation text, not from an absence-of-record probe — no openFDA registration lookup was made and none would have been evidence either way; (b) the claim's phrase "with FDA CVM" is not what was verified. 21 CFR 807.65(b)/807.20 are the FDA-wide device establishment registration and listing provisions; the exemption they establish is from that regime, not from something administered specifically by the Center for Veterinary Medicine. The substance of the claim is confirmed; the CVM attribution in its wording is not, and the Generator should drop or correct it.
claim 3unconfirmedUS
FDA retains post-market authority over animal devices under the misbranding/adulteration provisions of the FD&C Act, so labeling and claims remain an enforcement surface even without premarket review
jurisdiction: US — confidence: unconfirmed — source: statutory-interpretation claim; no connector in this repo serves the FD&C Act, CFR text, or FDA guidance documents, so nothing was queried. Needs FD&C Act §§ 501/502 and an FDA enforcement/guidance primary document, human-read. **Re-checked 2026-08-23 against the…the full check newly available regulation (eCFR) connector and deliberately not run:** that connector serves CFR text only, and this claim rests on (i) the statute (FD&C Act §§ 501/502 are not in the CFR) and (ii) FDA's enforcement practice toward animal devices, which is an interpretation question that regulation text does not answer even where a related section exists. Both are outside the connector's scope by construction, so the original reason for this tag still holds and no calls were spent re-confirming it. Remains unconfirmed; human-read.
claim 4verifiedUS
The equivalent human-use device would be Class II; NPWT powered suction pumps sit under FDA product code OMP (or a closely related code)
jurisdiction: US — confidence: verified — source: python3 -m connectors classification --product-code OMP --jurisdiction US → status verified, source_ref openFDA device/classification product_code=OMP, detail: "Device class 2: Negative Pressure Wound Therapy Powered Suction Pump (regulation 878.4780, review…the full check panel SU)". Scope of this verification: it confirms the human-use counterfactual only, checked against the indication FDA attaches to product code OMP (a powered suction pump for negative-pressure wound therapy under 21 CFR 878.4780), not against this candidate's frontmatter intended_use: ("For use by licensed veterinarians and veterinary technicians ... in dogs and horses"), which FDA does not classify at all. If the indication were ever broadened to include humans, this record is the applicable classification; as long as the labeling stays animal-only, this line evidences nothing about the candidate's own pathway. Corroborated independently 2026-08-23 (tag unchanged, second primary source added):python3 -m connectors regulation 878.4780 --title 21 --jurisdiction US → source_ref eCFR versioner title-21, issue 2026-08-19, section=878.4780, text: "§ 878.4780 Powered suction pump. (a) Identification. A powered suction pump is a portable, AC-powered or compressed air-powered device intended to be used to remove infectious materials from wounds or fluids from a patient's airway or respiratory support system. ... (b) Classification. Class II." The regulation the openFDA record points to confirms Class II in its own text, so the human-use counterfactual now rests on two independent primary sources rather than one. Nothing here contradicts the existing tag. Note for a reader: the CFR identification text describes a general powered suction pump and does not itself mention negative-pressure wound therapy — the NPWT-specific reading comes from product code OMP's device name in the classification record, not from 878.4780. clearance-summary applicability checked and it does not apply to this file: the newly available Indications-for-Use connector requires a K-number, and this candidate cites none — the frontmatter predicate_or_analog names PICO 1.6 and V.A.C. as design analogs with no clearance number attached, and no K-number appears anywhere in the Claims section. Nothing was run, and nothing here is recorded as an absent indication. If the Generator ever attaches a K-number to the PICO analog, clearance-summary <K-number> becomes the required check on what it was actually cleared to do — and note that any such IFU would be a human-use indication, bearing on the counterfactual in this claim rather than on the candidate's own animal-only pathway.

US Patent 5,636,643 ("Wound treatment employing reduced pressure," Argenta and Morykwas, assigned to Wake Forest University, filed 1993-03-09, issued 1997-06-10) has expired

Fixable: set PATENTSVIEW_API_KEY and re-run.
claim 7unconfirmedUS
FTO risk concentrates not in the expired foundational NPWT patents but in live patents covering canister-free / superabsorbent single-use NPWT (Smith & Nephew PICO family) and in dressing-interface chemistry
jurisdiction: US — confidence: unconfirmed — source: not checkable as written. The patent connector takes a single patent_id and performs no landscape or assignee search, so a claim with no patent number in it has no queryable input; no run was possible. This remains unsearched rather than unverified.…the full check Resolvable only by a human-commissioned FTO landscape search (assignees Smith & Nephew / T.J. Smith & Nephew / BlueSky Medical / Solventum; CPC A61M1/90-A61M1/98) whose output numbers can then each be run back through patent. Permanently unanswerable by connector in its current monolithic form.

Peer-reviewed study exists: PubMed 27569833, "Negative pressure wound therapy using a portable single-use device for free skin grafts on the distal extremity in seven dogs"
jurisdiction: US — confidence: verified — note: (bibliographic existence only)** — source: python3 -m connectors literature "27569833[uid]" --since 2010-01-01 --until 2026-08-23 → 1 record, source_ref PubMed PMID=27569833, https://pubmed.ncbi.nlm.nih.gov/27569833/, title an exact match, Australian Veterinary…the full check Journal, 2016 Sep. What this verifies is only that the record exists. The connector returns a ScanResult that structurally carries no confidence tag and stamps every record "title only — not appraised, not evidence for any claim"; nothing about the study's design, n, endpoints, or results is verified here, and this line must not be read as evidence that single-use NPWT works on canine distal-limb grafts. Consistency flag raised 2026-08-23 re-verification pass — tag left UNCHANGED, no connector result contradicts it, and this is explicitly not a downgrade: this line's verified tag was derived from a literatureScanResult, and this pass has just tagged two other literature claims in this file unconfirmed on the ground that a ScanResult carries no confidence tag and has no to_claim_line() by construction (connectors/result.py). The same reasoning applied consistently would put this line and claim 10 at unconfirmed (bibliographic existence attempted) as well. The Verifier is not resolving that on its own initiative — it changes no tag it was not asked to check and obtained no contradicting result — but the file is currently internally inconsistent about whether a scan can support a verified tag, and a Scorer reading Factor 6 needs to know that before treating claims 8 and 10 as verified backing of any kind. Flagged for the Scorer and for a human.
claim 9unconfirmedUS
Peer-reviewed comparative result exists, and at abstract depth it is narrower and more equivocal than its title: AJVR 2022;83(10) (PMID 35973001) is an n=5 Beagle pilot on surgically created 2cm x 2cm full-thickness hemithorax wounds treated for 14 days. Control wounds developed granulation tissue faster and more abundantly, and showed greater wound contraction, epithelialization and fibroblast proliferation at study end; the authors conclude the device "is feasible but problematic in maintaining a vacuum, requiring frequent revisions of the dressing" and that "its benefits in wound healing remain unknown"
jurisdiction: US — confidence: unconfirmed — note: attempted and structurally unverifiable, not unattempted** — source: Generator-restated 2026-08-23 per backlog 3.5; independently re-run by the Verifier 2026-08-23: python3 -m connectors literature-detail 35973001 → ScanResult status found, 1 record,…the full check source_ref PubMed PMID=35973001 (efetch), https://pubmed.ncbi.nlm.nih.gov/35973001/,American Journal of Veterinary Research, 2022, structured abstract (OBJECTIVE / ANIMALS / PROCEDURES / RESULTS / CLINICAL RELEVANCE). Every element of the restated claim was checked against the retrieved abstract and matches it: the device is named as PICO™ 1.6 (Smith & Nephew Medical Ltd); "5 adult spayed female research Beagles"; "1 full-thickness 2-cm X 2-cm cutaneous wound ... on each hemithorax"; "pilot experimental study"; 14 days; and both quoted phrases are verbatim — "is feasible but problematic in maintaining a vacuum, requiring frequent revisions of the dressing" and "Its benefits in wound healing remain unknown." Why the tag is unconfirmed and can never be anything else through this repo:literature-detail returns a ScanResult, whose status vocabulary is found/none/unavailable — disjoint from the confidence vocabulary by deliberate construction — and which has no to_claim_line() renderer at all (connectors/result.py; phase2-spec.md Section 3). There is no code path that turns a scan into a tagged claim, and the record itself is stamped "a lead to read, not evidence for a claim." So a retrieved abstract raises what we know while leaving the claim unverifiable by any connector in this repo. This is a finding about the connector surface, not a failed check — do not re-run it expecting a different tag, and do not read this unconfirmed as "nobody looked." What would resolve it: a human reading the full text (AVMA Journals). One tension the Verifier records without resolving, because appraisal is not its job: the restatement leans on "benefits remain unknown," but the same abstract's RESULTS section reports control wounds better on every macroscopic and histologic measure it names — granulation tissue "developed faster and was more abundant in control wounds," and "wound contraction, epithelialization, and fibroblast proliferation were greater in control wounds at the end of the study." Whether n=5 supports the title's word "inferior" is a question for a human appraiser; the direction of every reported endpoint is unfavourable to NPWT, and a Scorer should not read the softened restatement as neutralising that. What changed, and why the tag was reset: the previous claim text asserted "inferior efficacy... for cutaneous wounds in dogs" read off the title alone, and Stage 2 scored Factor 6 at its floor on that reading. The abstract does not support a powered comparative inferiority finding — n=5, described by its own authors as a pilot, on 2cm x 2cm hemithorax wounds, which is not this candidate's anatomical site (distal limb) and not grafted wounds. "Benefits remain unknown" is a materially weaker statement than the title's "inferior efficacy". The tag is reset to unverified because the claim text is now materially different from the one that was previously checked. Two limits the Verifier must carry rather than resolve away: (a) literature-detail returns a ScanResult, which carries no confidence tag and cannot acquire one by construction — an abstract is a deeper pointer, not a verification, so this claim cannot reach verified through any connector in this repo; (b) an abstract is still not the full text — design, randomization, power and risk-of-bias remain unread, so nothing here licenses scoring this factor up either, only recognizing that the floor score rested on a title. A separate finding worth carrying to Factor 5: the authors report that a complete seal required adhesive spray and that vacuum maintenance "lessened over time", with self-limiting skin irritation in all dogs hampering attainment of negative pressure. This candidate's stated moat is precisely a fur-compatible adhesive drape and limb-conforming interface — the paper's dominant failure mode lands on the exact component the candidate proposes to engineer, which is a point in the moat thesis's favour rather than against it

Published feasibility work exists for canister-free NPWT on open wounds in horses (PMC6404353) and a scoping review of equine NPWT (PMC10458497)
jurisdiction: US — confidence: verified — note: (bibliographic existence only)** — source: python3 -m connectors literature "negative pressure wound therapy AND (horses OR equine)" --since 2016-01-01 --until 2024-12-31 → 7 records, including source_ref PubMed PMID=30841889, "Feasibility of a disposable…the full check canister-free negative-pressure wound therapy (NPWT) device for treating open wounds in horses", BMC Veterinary Research, 2019 Mar 6, and source_ref PubMed PMID=37624295, "Negative-Pressure Wound Therapy (NPWT) in Horses: A Scoping Review", Veterinary Sciences, 2023 Aug 6. Both titles match the two works described. Caveat on identifiers: the literature connector returns PMIDs, not PMCIDs, so the specific PMC6404353 / PMC10458497 numbers in the claim were not cross-checked (a WebFetch of the PubMed pages returned only a cookie notice); the PMIDs above are the citations of record. As with claim 8, existence only — title metadata, not appraised, no finding verified. Same consistency flag as claim 8, tag left UNCHANGED and not downgraded: this verified tag also derives from a literature ScanResult, which by construction carries no confidence tag — see the note on claim 8. Flagged for the Scorer, not resolved here. Incidental related record surfaced by the same run and not currently a claim in this file: PMID 34115409, "Limited added value of negative pressure wound therapy compared with calcium alginate dressings for second intention healing in a noncontaminated and contaminated equine distal limb wound model", Equine Veterinary Journal, 2022 May — a second negative-direction title, in the equine distal limb, i.e. this candidate's exact site. Flagged for the Generator/Scorer to add as a claim and for a human to read; not appraised and not verified here.

Reimbursement — there is no third-party payer code, HCPCS or otherwise, for veterinary NPWT; revenue is cash-pay at point of service, optionally offset by pet insurance reimbursement to the owner
jurisdiction: US — confidence: unconfirmed — source: structurally unanswerable here, and no run was made against it.hcpcs, payment, and coverage each take a specific code as input and can only test whether that given code exists, pays, or has a policy; none can enumerate the non-existence of any code for…the full check a service, and no CMS code set covers animal care in the first place. A null return from those connectors would be the expected correct result rather than evidence, so querying an invented code to manufacture one would be meaningless. The second half of the claim (cash-pay + pet-insurance offset) is a market-structure assertion with no connector at all. Settled only by human-attached veterinary practice-economics sources.

Second comparative veterinary result exists, at this candidate's exact anatomical site: Equine Vet J 2022 (PMID 34115409), "Limited added value of negative pressure wound therapy compared with calcium alginate dressings for second intention healing in a noncontaminated and contaminated equine distal limb wound model" — a controlled experiment on circular wounds created on the dorsomedial metacarpus of 10 horses (5 contaminated with S. aureus and P. aeruginosa), one limb NPWT and the contralateral limb calcium alginate. In noncontaminated wounds NPWT gave significantly less wound retraction in early healing (mean difference 19.2% [95% CI 13.3-25.1], P = .005) and a significantly lower neutrophil / higher macrophage influx, with no difference in bacterial load or growth factors; in contaminated wounds no differences were observed on any measure. The authors state "[MAIN LIMITATIONS] Sample size is small" and conclude no long-term advantage over calcium alginate

Same structural ceiling as the AJVR line above:literature-detail returns a ScanResult (found/none/unavailable), a vocabulary deliberately disjoint from the confidence tags, with no to_claim_line() and therefore no code path to a tagged claim (connectors/result.py; phase2-spec.md Section 3); the record is stamped "a lead to read, not evidence for a claim." No connector in this repo can ever move this claim off unconfirmed — that is a property of the connector surface, not a failed lookup, and this line must not be read as unattempted. Resolution requires a human reading the full text. jurisdiction: n/a checked and accepted:literature-detail takes no --jurisdiction flag because PubMed is not a jurisdiction-bound source, and per CLAUDE.md the field is required on regulatory and reimbursement claims and harmless elsewhere — so the n/a here is correct rather than a missing tag, and the "conducted outside the US" note bears on generalizability only. Two things the abstract adds that the claim omits, recorded for whoever reads the full text: (a) treatment duration was only nine days for noncontaminated and six days for contaminated wounds, with measurements over 71 and 29 days respectively — short exposure windows that bear directly on the "no long-term advantage" conclusion; (b) the claim characterises the significant early retraction difference as "a significant early-healing benefit", but the abstract makes no such characterisation and immediately qualifies it — "although wound size was not significantly different between NPWT and control wounds at later healing stages." The direction is a source-reported difference; calling it a benefit is an appraisal the abstract does not license. Originally surfaced by the Verifier during the previous pass and correctly left for the Generator to enter rather than inserted by the agent that found it. Why it is entered as a distinct claim and not folded into the AJVR line: it is a different species, a different comparator (calcium alginate rather than a conventional dressing), and — unlike AJVR's hemithorax wounds — the distal limb, which is the site this candidate is designed for. What the Verifier must carry rather than resolve: (a) literature-detail returns a ScanResult with no confidence tag and no way to acquire one, so this claim cannot reach verified through any connector here; (b) the title reads more negative than the body — a significant early-healing benefit in noncontaminated wounds sits inside a paper whose conclusion is "no long-term advantage", and the abstract is not appraised for design, blinding, power or risk-of-bias; (c) n=10 with the authors' own small-sample caveat. This is a lead to read, not evidence for a score in either direction

A dog will tolerate a pump-and-drape assembly on a distal limb for the full treatment period under normal home conditions, without removing or chewing it off
jurisdiction: US — confidence: unconfirmed — source: no connector in this repo reaches this claim, and none was run. This is an animal-behavior/bench-tolerance claim, not a claim about what a person (clinician, payer, patient) would do, so adoption — which is scoped explicitly to human stakeholder preference —…the full check is a category mismatch and running it would manufacture a typed-looking result for an untyped question. No other connector in this repo addresses animal behavior. Resolvable only by a controlled tolerance study or a structured caseload of at-home device-removal/chewing incident rates; the equine case series already in this file (claim 15, PMID 34670699) reports "well tolerated except in 1 horse" as an incidental finding, but that is a different species, a different claim, and not independently re-verified as backing for this line.

Veterinary technicians can apply a fur-compatible drape and achieve a working seal reliably in ordinary practice conditions, without specialist training or adhesive spray
jurisdiction: US — confidence: unconfirmed — source: no connector in this repo reaches this claim, and none was run. This is a procedural/human-factors bench claim about a device that does not yet exist (no fur-compatible drape has been built or field-tested), not a regulatory, reimbursement, IP, market, or…the full check literature-existence claim any connector here answers, and not squarely a stakeholder-preference claim either (adoption covers what a person would choose to do, not whether a described technique works in their hands) — running adoption on it would be a category mismatch. Note the AJVR paper already in this file (claim 9, PMID 35973001) reports the opposite direction for the closest real-world analog: "self-limiting skin irritation in all dogs hampering attainment of negative pressure," i.e. a trained study team, not a technician in ordinary practice conditions, still had seal-maintenance problems with this general class of device. That is existing negative evidence on the underlying mechanism, not on this specific claim, and is not read as resolving it either way. Resolvable only by a human-observed usability study in a live veterinary practice.

Class-3 stakeholder-future claim per docs/research-lane-spec.md §3, no primary research substituted. Note the equine case series already in the file (claim 15, PMID 34670699) does report post-discharge use ("26% (11/42) were discharged before NPWT was considered ideally complete"), which is adjacent revealed-behaviour evidence about a practice's discharge decision, but it is a different species, a different claim, and not re-verified here as backing for this line. Permanently unconfirmable absent a structured survey of ACVS/AAEP practices.

Stays unconfirmed permanently unless a human attaches a licensed report and edits the claim by hand." This is a current-pricing claim, treated like the file's other price/volume claims (12-14) and run through market rather than adoption since it asserts an observable current fact rather than a future stakeholder choice — but no connector covers veterinary distributor pricing either way. Needs a veterinary distributor price file (Covetrus, Patterson Veterinary) cross-referenced against published PICO US list/contract pricing, human-attached.

Treated as an adoption-shaped claim because it asserts a business decision (a distributor's choice to carry an unbuilt SKU), not an existing catalog fact — a genuinely checkable version of this claim ("does Covetrus/Patterson already list a vet-labeled NPWT SKU") would require a distributor catalog, which no connector in this repo reaches either. Permanently unconfirmable absent human-attached distributor catalogs/price files or direct outreach.
claim 27unconfirmedUS
Gross margin at the proposed practice price supports a distributor sales motion after dressing cost of goods and sterile packaging validation
jurisdiction: US — confidence: unconfirmed — source: not checkable by any connector in this repo. This is a financial-modeling claim (COGS, packaging validation cost, distributor margin stack) with no registry, database, or market API behind any of its inputs — the same structural gap already recorded against…the full check claim 18 (capital intensity) in this file. No run was made; running market against a margin-structure sentence would not be answering the claim, it asks for a TAM figure, not a cost model. Needs human-attached contract-manufacturer/packaging-validation quotes and a distributor margin schedule (Covetrus, Patterson Veterinary).

A fur-compatible adhesive drape can hold a seal at approximately -80 mmHg on a canine or equine distal limb for at least 72 hours of normal ambulation
jurisdiction: US — confidence: unconfirmed — source: not checkable by any connector in this repo. This is a bench/engineering feasibility claim about a component that does not yet exist; no registry, regulatory, or literature connector speaks to unbuilt hardware performance, and no run was made. The closest…the full check existing evidence in this file is negative-direction and about a different (foam, not fur-compatible-drape) interface: the AJVR abstract (claim 9, PMID 35973001) reports the tested device was "feasible but problematic in maintaining a vacuum, requiring frequent revisions of the dressing," with self-limiting skin irritation hampering negative pressure — that bears on the general difficulty of this engineering problem but is not evidence for or against this specific drape design. Resolvable only by bench and in-vivo seal-duration testing.
claim 29unconfirmedUS
The limb-conforming interface layer survives normal animal behaviour and standard bandage-over-dressing practice without loss of seal
jurisdiction: US — confidence: unconfirmed — source: not checkable by any connector in this repo. Bench/engineering feasibility claim about unbuilt hardware; no run was made for the same reason as the two preceding feasibility-deck lines. Resolvable only by bench and in-vivo durability testing.

Adhesive and drape contact on furred distal-limb skin produces irritation below the level that hampers attainment of negative pressure
jurisdiction: US — confidence: unconfirmed — source: not checkable by any connector in this repo. Bench/clinical-tolerance claim about unbuilt hardware; no run was made. Flagged as the single highest-value item to watch of the four feasibility-deck claims, because the AJVR abstract already in this file (claim 9,…the full check PMID 35973001) reports the opposite — that a comparable device caused "self-limiting skin irritation in all dogs hampering attainment of negative pressure" — as a finding on a different adhesive/foam interface, not this candidate's proposed drape, so it neither confirms nor refutes this line, but it is the closest primary evidence on the exact failure mode this claim asserts away. Resolvable only by an in-vivo irritation/tolerance study.

Sterile packaging and single-use dressing tooling can be validated to a standard that supports the labelled claims, in the absence of any premarket review
jurisdiction: US — confidence: unconfirmed — source: not checkable by any connector in this repo. No connector prices or attests to ISO 11607 sterile-barrier validation or dressing-tooling qualification — the same gap already recorded against claim 18 (capital intensity). Its second half ("in the absence of any…the full check premarket review") also inherits directly from claim 1, itself still unconfirmed. Needs a human-attached packaging-test-lab validation plan/quote.

Cold re-retrieval matches the claim closely: the abstract's RESULTS state "(1) Based on the retrospective study, 20% ceased NPWT prematurely because of experienced limitations in daily activities" and its CONCLUSION restates "In 20% NPWT was prematurely ceased at the request of the patient." Both figures and the causal reason in the claim are verbatim-supported. Note this is a human-patient study, correctly stated as such in the claim text — it is not canine/equine evidence and must not be read as bearing on this candidate's animal tolerance claims above. Why the tag is unconfirmed and cannot be otherwise through this repo: literature-detail returns a ScanResult (found/none/unavailable), a vocabulary deliberately disjoint from confidence tags, with no to_claim_line() renderer (connectors/result.py; phase2-spec.md Section 3) — there is no code path from this connector to a verified tag, consistent with the treatment already applied to claims 9 and 20 in this file. Not appraised for design, sample size, or risk of bias beyond what the abstract itself states.

Every figure in the claim matches the retrieved abstract verbatim: "29 studies enrolling 5614 patients," "sNPWT reduced the number of SSIs (OR 0.37 ...)," "reduced the odds of wound dehiscence (OR 0.70 ...), seroma (OR 0.23 ...) and necrosis (OR 0.11 ...)," and the device is confirmed as PICO™ ("PICO™ sNPWT with conventional dressings"). One scope note for a later reader: this is a review of closed surgical incisions (post-surgical prophylaxis), not open or grafted wounds — the claim text does not say otherwise but a Scorer should not read this as evidence about this candidate's open/grafted distal-limb indication. Why unconfirmed, not verified: same structural ceiling as the line above — literature-detail returns a ScanResult with no code path to a confidence tag (connectors/result.py). Not appraised for risk of bias, publication bias, or heterogeneity beyond the abstract's own text.

In a retrospective matched-pairs comparison of 50 dogs, wounds treated with NPWT had significantly fewer complications (p=0.008) and significantly less sepsis (p=0.016) than wounds treated with a foam dressing, and healed faster than conventional bandaging

"Dogs (n = 50)" matches; "wounds treated with NPWT suffered significantly less complications (p = 0.008) and were significantly less septic during treatment (p = 0.016) than wounds treated with a foam dressing" matches verbatim. The claim's "healed faster than conventional bandaging" is directionally supported by the CONCLUSION ("time to healing was halved in NPWT treated patients compared to foam dressing treated patients, which in turn healed faster than patients treated with conventional bandage") but note the chain: the abstract's own comparison of NPWT to bandage is indirect, mediated through the foam-dressing group, not a direct NPWT-vs-bandage pairwise result — group A (bandage, n=7) was paired only against group C (foam), not against group B (NPWT, n=18) directly. This nuance is not captured in the claim's flatter phrasing. Why unconfirmed, not verified: same structural ceiling as the two lines above (ScanResult, no to_claim_line()). Not appraised for design or bias beyond the abstract's own text.

Matches closely: "Seven dogs were treated with portable NPWT after receiving skin grafts"; "distal extremities"; "Minor complications consisted of fluid accumulation in the evacuation tubing"; "All dogs achieved 100% graft survival." One word not literally in the abstract: "canister-free" — the abstract calls it a "portable single-use negative pressure wound therapy device" and does not use the word "canister" at all, so the canister-free characterization is consistent with but not verbatim-confirmed by this abstract (it is confirmed at claim 8's level, which already established the device as PICO-class canister-free hardware). Why unconfirmed, not verified: same structural ceiling as the class-2 lines above — literature-detail returns a ScanResult with no code path to a confidence tag. Not appraised for design or bias beyond the abstract's own text.

Every figure matches verbatim: "clinical records of 42 (n = 42) animals"; "Duration of NPWT application ranged from 2 to 36 days (mean 11.5)"; "In 69% (n = 29) of the cases, healing was considered satisfactory at discharge"; "26 % (n = 11) of horses were discharged whilst ideally NPWT should have been continued"; "2 animals (n = 2; 5%) were euthanized after surgery due to unrelenting pain." One thing worth flagging that the claim's framing does not surface: the euthanasia is reported as occurring "after surgery," and the abstract does not attribute the pain to NPWT itself as opposed to the underlying wound or surgical procedure — the claim's juxtaposition ("... and 2/42 were euthanized ... for unrelenting pain") could be read by a downstream Scorer as implying an NPWT-caused adverse event, which the abstract does not establish either way. Also worth noting for Factor 6/desirability: "The procedure was well tolerated except in 1 horse" is in the abstract but not carried into this claim. Why unconfirmed, not verified: same structural ceiling as the class-2 lines above.

51% (19 of 37) of FDA device recalls for canistered NPWT powered suction pumps (product code OMP) initiated 2011-08-31 through 2026-08-27 name a canister, dressing-connector, or tubing defect as the stated recall reason

The Verifier independently recounted the numerator against the raw record set (37 individual recall records, each with its own reason/root-cause text and recalled-device name) rather than taking the claim's count on faith: 16 records' reason text literally names a canister, connector, or tubing defect (e.g. Z-1596-2024/Z-1597-2024 "particulate matter ... entering the ... canisters"; Z-2543-2020/Z-2544-2020 "oversized O-ring ... into the mating connector"; Z-0039/0040/0041-2015 "canisters exhibiting ... deformation"; the eight 2014 Prevena recalls, "the male connector on the tubing is difficult to connect to the female connector on the ... canister tubing"), and 3 more name a canister as the recalled device itself even though the stated reason text uses different words (Z-2171-2017 "1000 ml Canister ... Potential sterile barrier breach"; Z-1067-2014/Z-1068-2014 "a Canister Component ... Modification of the bacterial overflow guard"). 16 + 3 = 19 of 37 = 51.4%, matching the claim's figure exactly under that reading. This is not free of judgment calls, on record for a human/Corroborator to check: six 2014 Smith & Nephew "Soft Port" recalls (Z-1157 through Z-1162-2014) describe a sealing/port failure adjacent to a dressing connector in substance but do not use the words "canister," "connector," or "tubing" in the reason text — the Verifier did not count these, and counting them would raise the total to 25/37 (68%). So the claim's specific 19/37 is corroborated under a literal-keyword-plus-device-name reading, but the true share is sensitive to where the line is drawn on borderline dressing-port failures, and the claim does not disclose that sensitivity. Why unconfirmed, not verified, despite the count checking out: recalls is a Stage 0 scan connector and returns a ScanResult, which — per phase2-spec.md Section 3 and connectors/result.py — carries no confidence-tag vocabulary and has no code path to acquire one, by the same structural rule already applied to the literature-detail claims in this file. A well-corroborated count from a scan is still not a tagged claim.

Scope note: this study uses PVA foam directly under NPWT, not the canister-free superabsorbent-dressing format central to this candidate's mechanism — a different interface from the PICO-class devices in claims 8/13/94 above, which the claim text does not flag. Why unconfirmed, not verified: same structural ceiling as the other class-2 lines in this file (ScanResult, no to_claim_line()).
claim 39unconfirmedUS
A 2026 equine wound-healing commentary states that isolated use of PICO-system NPWT in a small case series was not sufficient to stimulate healing, with no reduction in wound size observed, and that recent literature reviews found no solid evidence on best practices for equine distal-limb wound healing, calling many results controversial

Per the Verifier's standing instruction, a DOI-to-PMID lookup was not attempted via WebFetch or a generic search, since that would substitute an ad hoc web lookup for a typed connector call on exactly the claim this repo is built to guard against fabricating. If a corresponding PMID exists for this DOI, the Generator/Researcher should attach it and this line becomes checkable via literature-detail like the others in this batch. As written, this is a negative-direction finding at this candidate's core mechanism and exact species/site and should be flagged to a human for direct retrieval regardless of tag status.
