Endovascular graft

摘要

Disclosed is a medical device graft arrangement comprising a main graft and at least one peripheral graft wherein the grafts are expandable. Upon insertion of the peripheral graft(s) into the main graft, the peripheral grafts expand and seal the junction of the graft arrangement to provide fluid communication between the lumens of the main and peripheral grafts. The graft arrangement optionally has a cover folded in such a manner to provide further sealing.
