Title
(EN) HIGH METAL TO VESSEL RATIO STENT AND METHOD
(FR) ENDOPROTHÈSE AYANT UN RAPPORT MÉTAL SUR VAISSEAU ÉLEVÉ ET PROCÉDÉ CORRESPONDANT
Abstract
(EN)
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.

L'invention concerne un procédé qui comprend le recouvrement de vaisseaux ramifiés émanant d'un vaisseau principal et d'un anévrisme avec une endoprothèse ayant un rapport métal sur vaisseau élevé. Un rapport métal sur vaisseau de l'endoprothèse ayant un rapport métal sur vaisseau élevé est suffisamment élevé pour favoriser la croissance de tissu autour de l'endoprothèse ayant un rapport métal sur vaisseau élevé et cependant suffisamment faible pour garantir la perfusion des vaisseaux ramifiés par l'endoprothèse ayant un rapport métal sur vaisseau élevé. La croissance de tissu fournit une fixation et un scellement étanche fiables de l'endoprothèse ayant un rapport métal sur vaisseau élevé au vaisseau principal et remodèle et élimine essentiellement l'anévrisme. En outre, comme toute l'endoprothèse ayant un rapport métal sur vaisseau élevé est perméable, l'endoprothèse ayant un rapport métal sur vaisseau élevé est déployée sans avoir à positionner de façon rotative l'endoprothèse ayant un rapport métal sur vaisseau élevé.
