Abstract:
1. An implantable ligament or tendon bioprosthesis, comprising: a flexible implantable biocompatible construct comprising polymerized collagen fibers having opposing first and second end portions, wherein the construct is configured as an array of substantially parallel polymerized synthetic collagen fibers; a first suture wrapped laterally at least once about a perimeter of the first end portion of the construct and tied with a first square knot; and a second suture wrapped laterally at least once about the perimeter of the second end portion of the construct and tied with a second square knot, wherein each suture has a pair of suture legs that extend away from the respective square knot for affixing the construct to local bone or tissue, and wherein the sutures are resorbable and adapted to anchor to local tendon or ligament structure, wherein each of the first and second sutures are further wrapped around the respective end portion of the flexible construct and further tied with a respective pair of half-hitch knots such that each respective pair resides substantially symmetrically across from each other on opposing lateral sides of the construct so that the pairs of the suture legs both extend axially away from the construct from a respective exit location that is laterally outside the bounds of the construct, and wherein one leg in each pair is transversely spaced apart from the other so that a first leg in each pair extends axially away from the construct adjacent a first long side of the construct and a second leg in each pair extends axially away from the construct adjacent an opposing second long side to attach to local tendon or ligament structure.
