Abstract
The present invention is directed to the use of a stented graft 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 lateral opening of a main stent supporting a main artery has a collar with either at least two detents or inlets spaced about the annular extent thereof. The main collar mates with a collateral collar provided at the proximal end of the collateral stent having the other of at least two detents or inlets spaced about the annular extent thereof at intervals coincident with the inlets or detents on the main collar to mate and lock the main stent to the collateral stent supporting a collateral artery.
