Biodegradable composite yarn structure and method

Abstract

The techniques of this disclosure generally relate to prosthesis formed from a biodegradable composite yarn. The biodegradable composite yarn includes a permanent core and a biodegradable shell. The biodegradable shell slowly dissolves over a period of time when placed in a vessel. As the biodegradable shell dissolves, openings are created in the prosthesis that are filled with tissue from the vessel wall of the vessel. The integration of the tissue into the prosthesis provides biological fixation of prosthesis in the vessel and prevents endoleaks and migration of prosthesis.
