High metal to vessel ratio stent and method
First Claim
1. A prosthesis comprising:
- a plurality of serpentine rings comprising struts;
fingers protruding from the struts, wherein a metal to vessel ratio of the prosthesis when in a final configuration is within the range of 30 percent to 80 percent such as to encourage tissue ingrowth around the prosthesis while allowing perfusion of a branch vessel through walls the prosthesis.

Abstract
A method includes covering ostai of branch vessels emanating from a main vessel and an aneurysm with a high metal to vessel ratio stent. A metal to vessel ratio of the high metal to vessel ratio stent is sufficiently high to encourage tissue ingrowth around the high metal to vessel ratio stent yet is sufficiently low to ensure perfusion of the branch vessels through the high metal to vessel ratio stent. The ingrowth of tissue provides secure fixation and sealing of the high metal to vessel ratio stent to the main vessel and remodels and essentially eliminates the aneurysm. Further, as the entire high metal to vessel ratio stent is permeably, the high metal to vessel ratio stent is deployed without having to rotationally position the high metal to vessel ratio stent.
