Post-market Study of the Biodesign Hernia Graft

The Biodesign Hernia Graft is comprised of 8 layers of decellularized porcine small intestinal submucosa (SIS) that has been pressed-lyophilized (i.e., freeze-dried under vacuum pressure) to laminate the component sheets (i.e., layers) together. In addition, it is perforated and sewn with 4-0 Trisorb suture (polyglycolic acid (PGA); Samyang Corporation, Seoul, South Korea). The suture is distributed in a diamond pattern across the graft and along the periphery and is intended to mitigate delamination of the layers upon rehydration and/or manipulation during implantation. Being a completely biologic device, the Biodesign Hernia Graft is considered MR safe.
