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.
