摘要： A variable zone high metal to vessel ratio stent includes a proximal high metal to vessel ratio zone, a central low metal to vessel ratio zone, and a distal high metal to vessel ratio zone. The proximal high metal to vessel ratio zone is deployed with fixation and sealing to healthy tissue of a main vessel superior to branch vessels and an aneurysm. The central low metal to vessel ratio zone is deployed directly on ostai of the branch vessels. However, as the central low metal to vessel ratio zone is highly permeable, blood flows from the main vessel through the central low metal to vessel ratio zone and into branch vessels.

摘要： 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.
