Abstract
A prosthesis consisting of a flexible thin-walled sleeve for reinforcing and repairing a damaged vessel and a process of placing the flexible sleeve in the vessel by collapsing the sleeve radially onto an expandable and contractable member and encasing the member and sleeve in a sheath; and then sliding the sleeve in place in a vessel covering the damaged area of the vessel and removing the sheath; then expanding the expandable member and the sleeve so that the sleeve covers the damaged area and forms a sealed interface on its outer peripheral ends with the inner peripheral surface of the vessel to thereby provide a bridging passage across the damaged area in the vessel. The device provides a process to reinforce or repair weakened, damaged, narrowed blood vessels or to divert flow in branching vessels. The sleeve is a flexible, plastic, thin-walled sleeve molded with various types of ribs and reinforcements to be used as an endovascular prosthesis. It also includes a means of delivering the prosthesis to the damaged blood vessel without surgery. With the device a physician may patch the inside of a blood vessel without performing an arteriotomy and without the use of an operating …
