VEMERIX evidence review cover comparing PVA vs PU foam materials, pore mechanics, and open vs closed-incision NPWT change intervals.

Negative Pressure Wound Therapy Dressing Selection: What the PVA-versus-PU Foam, Pore-Size and Closed-Incision-versus-Open-Wound Evidence Actually SupportsNavigating NPWT dressing selection requires separating material mechanics from clinical healing claims—evaluating open-pore PU black foam (400–600 µm) for high-exudate granulation against hydro-retentive PVA white foam for sensitive wound beds, respecting the 48–72 hour open-wound change boundary, and understanding the FDA regulatory divide between open-wound (OMP) and closed-incision (QFC) devices.August 3, 2026 · 15 min read

How to Specify a Negative Pressure Wound Therapy (NPWT) System: A Lot-by-Lot Tender, RFQ & Acceptance Checklist for Pumps, Dressings and Canisters (2026)A hospital procurement, health-system category management, or distributor team specifying negative pressure wound therapy (NPWT) should not issue a single bundled RFQ. Structure tenders into platform lots (acute heavy-duty, portable ambulatory, single-use/disposable, consumables, rental), map every pump performance and alarm requirement directly to documented FDA failure modes (leak, occlusion, canister overflow, power thermal cutoff), and demand a 6-part regulatory evidence pack (510(k), UDI, ISO 10993, IEC 60601-1, EO sterilization) before awarding volume.August 3, 2026 · 18 min read

The Line That Decides the Class: How a Wound Dressing's Claim — Not Its Chemistry — Sets Its Regulatory Class in the US, EU and ChinaIn wound and skin care the label claim, not the material, sets the regulatory class — and because most of the category is 510(k)-exempt in the United States, the public clearance record systematically under-describes who actually supplies it. A primary-source read of 31 FDA product codes, EU MDR Rule 4 and NMPA's 2022 catalogue change.July 27, 2026 · 27 min read

The Single-Use Turn: Why Four Minimally-Invasive Device Lines Are All Migrating From the Durable Machine to the Registered Consumable — and What It Means for How You SourceAcross four unrelated device lines — vein ablation, wound therapy, circumcision, aesthetic injection — the same shift recurs: the durable machine commoditizes and value migrates to the registered single-use consumable. One pattern, three economic engines, and one sourcing conclusion: buy the platform, not the SKU.July 20, 2026 · 21 min read
