BTM Wound Dressing

A unique synthetic biodegradable wound matrix BTM is a synthetic, biodegradable and biocompatible device designed to facilitate the dermis to grow within a patented polyurethane foam matrix. When ready, the sealing membrane is removed, leaving a fully vascularised dermis, ready for closure.
BTM Advantages
  • Fully synthetic, fully biodegradable and biocompatible, with no biological material.
  • No preparation, ready to use.
  • Physiologically seals the wound – healing can begin.
  • Clinically choose when to delaminate.
  • Designed to minimise scarring and contracture.
