Bilayer Wound Matrix.

TheraGenesis Bilayer Wound Matrix is a collagen-based wound dressing that consists of two layers: a porcine tendon-derived atelocollagen sponge layer and a silicone film layer. It contains a non-adhesive gauze (TREX™) to reinforce the silicone film. The meshed type has slits to aid in the drainage of exudate. The biodegradable collagen matrix provides a scaffold for cellular invasion and capillary growth.


TheraGenesis Bilayer Wound Matrix is indicated for the management of wounds including:

  • Partial and full-thickness wounds
  • Pressure ulcers
  • Venous ulcers
  • Diabetic ulcers
  • Chronic vascular ulcers
  • Surgical wounds (donor sites/grafts, post-Moh’s surgery, post-laser surgery, podiatric, wound dehiscence)
  • Trauma wounds (abrasions, lacerations, second-degree burns, and skin tears)
  • Draining wounds


  • TheraGenesis Bilayer Wound Matrix may exacerbate conditions in patients showing sensitivity to porcine-derived products (such as insulin), or silicone materials
  • Do not use in patients with a history of hypersensitivity to proteins of animal origin
  • Do not use in infected wound sites (e.g., infected chronic ulcers, etc.)
  • This device is not indicated for use in third-degree burns
