Patent ID: 8450431

Claim:
A medical device produced from a process comprising (i) the step of injection molding or extruding the medical device from a bimodal polymer composition or (ii) the step of subjecting a medical device made from said bimodal polymer composition to a heat treatment step; said bimodal polymer composition composing a blend of: (a) from about 60 to 80 wt % of a first component which is a semi-crystalline polylactide polymer having a first weight average molecular weight distribution between about 300,000 to about 2,000,000 Daltons; and (b) from about 20 to 40 wt % of a second component which is a semi-crystalline polytactide polymer having a second weight average molecular weight distribution between about 10,000 to about 50,000 Daltons, the weight average molecular weight ratio of said first molecular weight distribution to said second molecular weight distribution is at least about two to one; wherein said blend has an isothermal crystallization half time of less than that of either individual blend component over a temperature range of between about 130° C. to about 150° C. and a degree of crystallinity from about 10% to about 50% after said steps (i) or (ii).
