摘要:
Disclosed herein is a high strength, bioresorbable wall thickness suitable for use in an endoprosthesis such as a stent that is produced by first forming a wall thickness by melt processing or solution processing one or more bioresorbable materials into a tubular shape drawing the shape from shorter length to an optimum longer length and reducing the diameter from a larger diameter to a smaller diameter to orient the molecular chains of the material fabricating a stent from the tube formed of the oriented material by cutting a strut pattern in its wall thickness covering the stents struts with at least one coating to delay degradation of the bioresorbable material covering the stents struts with one or more controlled release active ingredients to minimize the risk of restenosis or other side effects crimping the stent onto a balloon catheter assembly delivering the stent into an anatomical lumen via percutaneous methods to a treatment location radially expanding the stent from a smaller size to a larger size at the treatment location wherein the stent temporarily supports the anatomical lumen and removing the catheter from the lumen.
