1. A laminated prosthesis for repairing a diseased area in a vessel comprising:
- a first tubular layer having a proximal end and distal end defining a lumen through said diseased area, said proximal end engaging a first surface of said vessel upstream of said diseased area and said distal end engaging a second surface of said vessel downstream of said diseased area; and
a second tubular layer disposed in said first tubular layer, said second tubular layer being deployed in said first tubular layer in vivo.

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.

14. A prosthesis for repairing a diseased area in a vessel comprising:
-
a first tubular member having a proximal end and a distal end, said proximal end engaging a first surface of said vessel outside of said diseased area and said distal end extending into said diseased area; and
one or more overlapping other tubular members, each other tubular member having a proximal end and a distal end, wherein a proximal end of one of said other tubular members being in an overlapping relationship with said first tubular member and a distal end of one of said other tubular members engaging a second surface of said vessel outside of said diseased area, wherein said first and other tubular members define a lumen through said diseased area. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23, 24)

25. A method of directing flow through a blood vessel, the method comprising steps of:
-
disposing a first tubular member in a contracted configuration on a delivery system;
advancing the delivery system inside said vessel to dispose the first tubular member at the desired location within the vessel;
actuating the delivery system to deploy the first tubular member at the desired location;
disposing a second tubular member in a contracted configuration on a delivery system;
advancing the delivery system along a guide wire to dispose the second tubular member at the desired location within the vessel; and
actuating the delivery system to deploy the second tubular member in an overlapping relationship with said first tubular member forming a prosthesis having an external wall. - View Dependent Claims (26, 27, 28, 29, 30)
