Abstract
Abstract The present invention provides a prosthesis formed from a plurality of tubular layers members deployed in vivo using endovascular techniques and material. The layers define a lumen through a diseased portion of a vascular system. Each layer may be constructed using overlapping tubular members to provide a custom prosthesis. Subsequent prosthesis layers overlapping in the central portion of the lumen strengthen the prosthesis walls and may incorporate biocompatible materials having desirable properties.
