    Abstract: Novel absorbable polymeric blends having bimodal molecular weight distribution are disclosed. The bimodal blends have a first component that is a polylactide polymer or a copolymer of lactide and glycolide having a bimodal molecular weight distribution, and a second component that is a poly(p-dioxanone) polymer of unimodal or bimodal molecular weight distribution. Alternately, the bimodal blends have a first component that is a polylactide polymer or a copolymer of lactide and glycolide having a unimodal molecular weight distribution, and a second component that is a poly(p-dioxanone) polymer of bimodal molecular weight distribution. The novel polymeric bimodal molecular weight blends provide medical devices having improved dimensional stability. Also disclosed are novel absorbable medical devices made from these novel bimodal polymer blends, as well as novel methods of manufacture.

    Abstract: A co-polyester which includes the reaction product of a polycondensation polyester and epsilon-caprolactone, wherein the polycondensation polyester comprises the reaction product of diglycolic acid and/or a derivative thereof and a diol. The co-polyester is injectable and absorbable into animal, such as human, tissue and can be used for facial cosmetic or reconstructive surgery of soft tissue. Another embodiment is directed to a method for preventing adhesion using a co-polyester comprising the reaction product of a polycondensation polyester and epsilon-caprolactone, wherein the polycondensation polyester comprises the reaction product of diglycolic acid and/or a derivative thereof and a diol, and the co-polyester comprises about 40 to 50% by weight of the polycondensation polyester based on the total weight of the co-polyester.
