Abstract

Disclosed herein is a high radial strength, filament-reinforced bioresorbable stent comprising extruding a polymer into one or more small diameter filaments; stretching the extruded filaments to an optimum longer length; organizing one or more of the stretched filaments into a tubular shape; thermoforming the tubular shaped filaments to substantially retain a tubular shape; binding the filaments together with one or more bioresorbable polymers to produce a filament-reinforced tube; fabricating a stent from the filament-reinforced tube by cutting a strut pattern in the wall thickness of the tube; covering the stent with coating to delay hydrolysis and/or deliver an active ingredient to minimize the risk of restenosis; crimping the stent onto a balloon catheter assembly; delivering the stent into an anatomical lumen via percutaneous methods to a treatment location; expanding the stent at the treatment location wherein the stent temporarily supports the anatomical lumen; and removing the catheter from the lumen.
