Abstract
A resorbable, biodegradable, drug delivery prosthesis (10) includes mechanical properties for maintaining the strength needed to acutely open and maintain a vessel, duct, tract, or organ, and precise chronicity for controlling the release and delivery of drugs or biologic agents. The drugs and biologic agents are capable of acting upon and altering the mechanisms of biologic systems in an manner providing a medicinal therapy. The method of the invention includes a one step process of extruding the admixture forming the prosthesis (10) into a geometry compatible with its use.
