Abstract
Abstract A deformable surgical repair device is manufactured from a block or graft copolymer. The copolymer comprises 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 ε-caprolactone linkages. The plurality of first linkages comprises at least about 50 up to about 90 mole percent of the copolymer. In an alternative claim, the deformable surgical repair device is manufactured from a blend of a first and a second absorbable polymer. The first absorbable polymer comprises a plurality of linkages selected from the group consisting of glycolic acid ester and lactic acid ester linkages, and mixtures thereof. The second absorbable polymer comprises a plurality of linkages selected from the group consisting of 1,3-dioxan-2-one; 1,4-dioxan-2-one and ε-caprolactone linkages. The first absorbable polymer comprises at least about 50 up to about 90 weight percent of the blend. The device is useful in fracture fixation.
