摘要
Bioresorbable polymer vascular scaffolds made of combinations of polylactide and polycaprolactone having a high molecular weight polymer, thin struts in a selected range and sufficient radial strength to support a vessel upon deployment. The scaffolds have degradation behavior of molecular weight, radial strength, and mass that are conducive to healing of a vessel including providing patency to a vessel, reduction of radial strength, breaking up, and resorbing to allow return of the vessel to a natural state.
