Endoform Natural Dermal Template Collagen Dressings

Endoform is a natural dermal template made from ovine (sheep) forestomach tissue, preserving intact collagen along with glycosaminoglycans (GAGs), elastin, and other extracellular matrix components. Rather than acting as a passive cover, Endoform functions as a restorative bioscaffold — supporting the wound's own repair processes in stalled, chronic, and complex wounds where healing has plateaued. Clinicians reach for it on diabetic foot ulcers, venous leg ulcers, pressure injuries, surgical wounds, and skin tears.

The choice between formats comes down to the wound bed. Fenestrated templates, like the Aroa Endoform Fenestrated 4" x 5" and the Hollister Endoform Fenestrated 2" x 2", have small perforations that let exudate pass through to a secondary dressing — a better fit for moderately to heavily draining wounds. Non-fenestrated versions, such as the Aroa Endoform Nonfenestrated 4" x 5" and Hollister Endoform Nonfenestrated 2" x 2", suit drier or lightly exuding beds where you want maximum surface contact.

Where infection risk is a concern, the Endoform Antimicrobial Natural Dermal Template incorporates ionic silver into the collagen matrix, available in fenestrated and non-fenestrated 2" x 2" squares. This lets you keep the same restorative scaffold while adding a barrier against a broad range of wound bacteria.

A few practical notes buyers ask about: Endoform is applied directly to a clean, debrided wound bed and covered with an appropriate secondary dressing, which manages moisture and holds the template in place. It resorbs into the wound over time, so it typically doesn't require removal at each change — reducing disruption to fragile new tissue. All variants are sterile and single-use. Match the sheet size to your wound dimensions, trimming as needed, and keep the antimicrobial option on hand for beds showing signs of bioburden.
