METHOD AND DEVICE FOR PERFORMING ENDOVASCULAR REPAIR OF ANEURYSMS

摘要

A blood vessel wall-defining device and method for using the device for repairing an aneurysm. The device comprises in combination, a percutaneously-insertable structural frame, the structural frame being expansible to form a generally cylindrical structural skeleton (30) having a slightly larger diameter than the blood vessel, and an independently, percutaneously-insertable, expansible tubular member (40) constructed to be percutaneously placed subsequent to the placement of the structural frame, the tubular member comprising a thin-walled flexible tubular membrane (41) extending between the first and second ends of the tubular member, the thin-walled flexible tubular membrane being essentially impermeable to blood and blood products, and means for expanding and holding the thin-walled flexible tubular membrane adjacent to the inside of the structural skeleton, in a cooperative relationship therewith, in a manner that the outer surface of the thin-walled flexible tubular membrane is held in secure contact with the inside off the previously-placed structural skeleton.
