Abstract:
A surgical composite structure for mammalian tissue comprising:(a) a reinforcing component prepared from a plurality of fibers, the plurality of fibers manufactured from a biocompatible polymer, and(b) a permanently deformable at ambient temperature bioabsorbable component consolidated around said plurality of fibers to form a matrix, the bioabsorbable component having a flexural strain at break of greater than about 25% and a flexural strain at yield of greater than about 3%; the bioabsorbable component comprising (i) a blend of a first and second absorbable polymer, the first absorbable polymer comprising a plurality of linkages selected from the group consisting of glycolic acid ester and lactic acid ester linkages, and mixtures thereof, and the second absorbable polymer comprising a plurality of linkages selected from the group consisting of 1,3-dioxan-2-one; 1,4-dioxan-2-one and .epsilon.-caprolactone linkages, the first absorbable polymer comprising at least about 50up to about 90 weight percent of the blend, or (2) a copolymer selected from the group consisting of a block and graft copolymer, the copolymer comprising a plurality of first linkages selected from the group consisting of glycolic acid ester and lactic acid ester linkages, and mixtures thereof, and a plurality of second linkages selected from the group consisting of 1,3-dioxan-2-one; 1,4-dioxan-2-one and .epsilon.-caprolactone linkages, the plurality of first linkages comprising at least about 50 up to about 90 mole percent of the copolymer.
