1. A self-expanding tubular isolation sleeve for treatment of an aneurysm and reduction of endoleaks, comprising:

  • a self-expanding resilient frame including one or more resilient strands formed into a tubular structure that is configured to expand from a radially constrained state to a radially expanded state and conform to an irregular morphology of an abdominal aortic aneurysm;

    at least one tubular layer of thin flexible sheet material disposed on the resilient frame which has an outside surface that is configured to seal against an inner wall of an aneurysm and isolate a feeder vessel of the aneurysm; and

    a fusiform configuration wherein an outer profile of the tubular isolation sleeve in a relaxed unconstrained state is configured to roughly approximate a profile of an interior surface of a typical abdominal aortic aneurysm and wherein the outer profile includes a proximal reduced transverse dimension section at a proximal end thereof, a distal reduced transverse dimension section at a distal end thereof and an enlarged center section of greater transverse dimension than the proximal and distal reduced transverse dimension sections.
