Dissection prosthesis system and method
First Claim
1. A dissection prosthesis system comprising:
- a first prosthesis having a generally tubular shape, a radially compressed delivery configuration and a radially expanded deployed configuration, the first prosthesis comprising;
a plurality of stent rings, each of the plurality of stent rings having a proximal end and a distal end, wherein each of the plurality of stent rings includes a plurality of openings between the respective stent ring proximal and distal ends thereof; and
a plurality of graft material bands, each graft material band having a proximal edge portion and a distal edge portion and a plurality of band openings between the proximal edge portion and the distal edge portion;
wherein each one of the plurality of graft material bands is disposed between and couples together a respective adjacent pair of the plurality of stent rings such that each graft material proximal edge portion is attached to a respective stent ring distal end and each graft material distal end portion is attached to a respective proximal end of an adjacent stent ring; and
wherein the plurality of openings in the stent rings and the plurality of band openings in the graft material bands enable fluid flow from a lumen of the prosthesis through the openings and band openingswherein the graft material bands have a zig-zag shape in a longitudinal direction, wherein the plurality of band openings are formed between struts of the zig-zag shape.

Abstract
A dissection prosthesis system for implantation within a blood vessel includes a first prosthesis and a second prosthesis. The first prosthesis includes a first stent ring, a second stent ring, a first graft material band coupling the first stent ring to the second stent ring, a third stent ring, and a second graft material band coupling the second stent ring to the third stent ring. The second stent ring includes a plurality of openings that enable fluid flow from a lumen of the first prosthesis through the plurality of openings. The graft material bands may include band openings disposed therethrough to enable fluid flow from the lumen through the band openings. The second prosthesis includes a stent coupled to a graft material. The second prosthesis is configured to be disposed within the lumen of the first prosthesis.
