    • 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.
    • 一种方法包括覆盖从主血管发出的分支血管和具有高金属与血管比例支架的动脉瘤。 高金属与血管比支架的金属与血管比例足够高以促使组织向内生长高金属与血管比例支架,但足够低以确保分支血管通过高金属与血管比例的支架灌注。 组织的向内生长提供了高金属与血管比例支架到主血管的牢固固定和密封,并且改造并且基本上消除了动脉瘤。 此外,随着整个高金属与血管比例的支架是可渗透的,高金属与血管比例的支架被展开,而不必旋转地定位高金属与血管比例的支架。
