DESIGN AND ASSEMBLY OF FENESTRATED STENT GRAFTS

摘要

A method of sizing of a stent graft includes the steps of placement of fenestrations to ensure access to side branch vessels through the fenestrations when the stent graft is introduced into a body vessel. Assembly includes temporary diameter reduction arrangements to enable partial release of a stent graft to assist with positioning of fenestrations with respect to side branch vessels. The method includes spacing the fenestrations to be the same circumferential distance as the side branch vessels irrespective of the diameter of the stent graft.
