ABSTRACT:
The present invention contemplates the use of a grafted stent having predetermined and sized lateral openings for the treatment of arterial disease at or around the intersection of multiple arteries, thereby ensuring blood flow through such arteries to collateral organs. In particular, the point of intersection of the arteries to be treated is determined and the lateral openings are interposed within the stent and appended graft and the stented graft is positioned precisely at a premeasured point whereby the intersection of the arteries coincides with the lateral openings of the stented graft. The method and apparatus of the present invention further includes securing the lateral openings of the stented graft against a portion of the walls of the intersection point to guard against leaking or improper fit.
