Biodesign® – Dural Repair & Duraplasty Grafts

Biodesign Advanced Tissue Repair – handle with ease, repair with confidence
  • Providing a strong seal
  • Excellent handling
  • Sutured/Sutureless fixation


Biodesign® is a platform technology behind numerous tissue-repair products that span multiple medical specialties. Biodesign is natural extracellular matrix (ECM) derived from porcine small intestinal submucosa (SIS). The ECM is a complex latticework of proteins and structural molecules that helps guide the growth of cells.

Cook’s proprietary processing methodology decellularizes the SIS material while preserving natural matrix molecules such as collagen, proteoglycans, and glycosaminoglycans. The result is a scaffold that, when implanted, provides a location for host cells to infiltrate and remodel into vascularized tissue.

Biodesign Dural Repair

The Biodesign Dural Repair Graft is used as a dural substitute for repairing dura mater, it is easy for the surgeon to manipulate, doesn’t swell with hydration and doesn’t fold onto itself. Once placed it provides a strong seal and is completely remodelled into natural host tissue, with post-op leaks as low as 1.7% reported.

Tips to help get the best results include;

  • Ensure adequate blood supply
  • Size the graft to allow tissue overlap
  • Hydrate for at least 2 minutes before placement

Biodesign Duraplasty Graft

The Biodesign Duraplasty Graft is indicated for use as a dura substitute for the repair of dura mater. This graft is supplied sterile in peel-open packages and is intended for one-time use.

It shares the same characteristics as the rest of the Biodesign range and in this indication it is used as an onlay graft that can be secured in place with or without sutures, depending on clinician preference.
