Abstract:
1. A method of manufacturing a bioabsorbable medical device, comprising the steps of: processing a bioabsorbable polymer blend comprising 78 weight percent to 82 weight percent of a first bioabsorbable polymer and 18 weight percent to 22 weight percent of a second bioabsorbable polymer, the first bioabsorbable polymer comprising a lactide-rich polymer comprising 95 mol percent to 70 mol percent polymerized lactide and 5 mol percent to 30 mol percent polymerized glycolide, and the second bioabsorbable polymer comprising poly(p-dioxanone), wherein the maximum weight percent of poly(p-dioxanone) in the polymer blend is 22 weight percent and the minimum weight percent of poly(p-dioxanone) in the polymer blend depends upon the molar amount of polymerized lactide in the lactide-rich polymer and is calculated by the expression: and forming a bioabsorbable medical device from the polymer blend, wherein the polymer blend provides dimensional stability to the formed device.
