Abstract

Apparatuses and methods for quickly and accurately positioning a stent within the ostium of a blood vessel so that the entire circumference of the proximal stent edge is within the aorto-ostial landing zone (AOLZ). Any of these methods and apparatuses may include an ostial positioning catheter including an annular sealing balloon, a distal reinforced shaft, and a hypotube extending proximally from a longitudinal side of the distal reinforced shaft. These ostial positioning catheters may be independently operated with a guide catheter and a stent deployment catheter.
