Abstract:
1. A biocompatible, bioresorbable, knitted surgical scaffold for soft tissue reconstruction or repair, comprising: (a) a first set of yarns and a second set of yarns, the first set of yarns interlacing with the second set of yarns to define nodes, the first set of yarns and the second set of yarns alternately applied in a wale direction to form staggered loops, wherein the alternating application of the first set of yarns and the second set of yarns causes the first set of yarns to have different tensions relative to the second set of yarns at the nodes, and the difference in tension substantially preventing the knitted scaffold from unraveling at the nodes; and (b) regions of varying stretch to contour to a soft tissue shape for replacement or repair, the regions of varying stretch comprising a stretchy region and a U-shaped stiffer region, the stretchy region being surrounded by the U-shaped stiffer region, wherein the scaffold is bioresorbable and consists essentially of sericin-depleted silk.
