    摘要： A copolymer comprising a bioabsorbable, segmented molecular architecture has been invented. The copolymer has at least two different ester linkages. The segmented molecular architecture comprises a plurality of fast transesterifying linkages. The fast transesterifying linkages have a segment length distribution of greater than 1.3. The segmented molecular architecture also comprises a plurality of slow transesterifying linkages. The following proviso is a material limitation to this invention: for the fast transesterifying linkages consisting essentially of glycolate linkages and the slow transesterifying linkages selected from the group consisting of trimethylene carbonate and caproate linkages, the segment length distribution of the fast transesterifying linkages is up to 2.0 and the number average segment length of the slow transesterifying linkages is greater than 2.5 linkages per segment. The copolymer is useful as an article of manufacture, for example a molding resin, surgical element and controlled release device.

    摘要： 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 .epsilon.-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 .epsilon.-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.
