Abstract
Abstract A deformable surgical repair device is manufactured from either an absorbable copolymer comprising a plurality of first and second linkages or an absorbable blend of a first and second polymer. The copolymer first linkages and the first polymer in the blend are selected from the group consisting of glycolic acid ester and lactic acid ester linkages, and mixtures thereof. The copolymer second linkages and the second polymer in the blend are 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 or the first polymer comprise at least about 50 up to about 90 mole percent of the respective copolymer or blend. The device can be combined with a reinforcing component prepared from a biocompatible polymer. The device can be further manufactured from a nonabsorbable material comprising a fluorinated hydrocarbon polymer. The device can be a fracture fixation device, or a surgical clip or staple.
