Abstract
Compositions and blends of biopolymers and copolymers are described, along with their use to prepare biocompatible scaffolds and surgically implantable devices for use in supporting and facilitating the repair of soft tissue injuries.
Claims30
An implantable scaffold for supporting the repair of a soft tissue injury comprising at least one biopolymer sheet comprising substantially aligned biopolymer fibers,
- wherein the biopolymer fibers comprise:
- about 10 to 50% by weight of a collagen selected from the group consisting of atelocollagen, telocollagen, recombinant human collagen and mixtures thereof;
- and
- about 50 to 90% by weight of a copolymer selected from the group consisting of PLLA, PDLA, PDLLA, PLGA and mixtures thereof.
1 more element
An implantable scaffold for supporting the repair of a soft tissue injury comprising at least one biopolymer sheet comprising substantially aligned biopolymer fibers,
- wherein the biopolymer fibers comprise:
- about 27.5 to 32.5% by weight of a collagen selected from the group consisting of atelocollagen, telocollagen, recombinant human collagen and mixtures thereof;
- and
- about 67.5 to 72.5% by weight of a copolymer selected from the group consisting of PLLA, PDLA, PDLLA, PLGA and mixtures thereof;
- and
- wherein the average diameter of the fibers is in a range from about 750 to 1,200 nm.
