A bio-compatible and bioresorbable stent is disclosed that is intended to restore or maintain patency following surgical procedures, traumatic injury or stricture formation. The stent is composed of a blend of at least two polymers that is either extruded as a monofilament then woven into a braid-like embodiment, or injection molded or extruded as a tube with fenestrations in the wall. Methods for manufacturing the stent are also disclosed.

Abstract:
Bioresorbable, self-expanding stents intended to relieve stenoses occurring in organs, vessels, or other luminal structures within the human body are provided. The bioresorbable, self-expanding stents are composed of bioresorbable, biocompatible polymers. The bioresorbable stents provide openings that allow for tissue in-growth through the stent thereby fixing the stent in place and allowing the stent to be controllably degraded and excreted by the body.

Abstract:
A bio-compatible and bioresorbable medical device is disclosed. Specifically a polymeric stent is disclosed intended to restore or maintain patency following surgical procedures, traumatic injury or stricture formation. The polymeric stent is composed of one or more polymers that is either extruded as a monofilament then woven into a braid-like embodiment, or injection molded or extruded as a tube with fenestrations in the wall. Related methods for controlling the medical devices' in vivo functional life by controlling polymer monomer content and other polymer structural qualities are also provided.
