“…Porcine dermal collagen and small intestinal submucosa (SIS) have both been successfully used in a wide variety of surgical procedures to provide strength and support when soft connective tissues have been lost or damaged. 11,50,66,87,96,99 Derwin et al 26 examined the biochemical, biomechanical, and cellular properties of collagen-rich extracellular matrices, GraftJacket (Wright Medical Technology Inc, Arlington, Tennessee) and TissueMend (TEI Biosciences, Boston, Massachusetts), and 2 SIS grafts, Restore Orthobiologic Implant (DePuy Orthopaedics Inc, Warsaw, Indiana) and CuffPatch (Biomet Inc, Warsaw, Indiana). The SIS matrices were found to have higher elastic moduli than GraftJacket and TissueMend, and they reached their maximum elastic moduli at lower levels of stretch.…”
