ABSTRACT:
A catheter for insertion through a main artery into a branch artery ostium comprises a shaft, an integral profiled portion, and an integral tip portion. The profiled portion comprises a series of bends and straight legs. The tip portion of the catheter axially engages the branch artery. The profiled portion is shaped and dimensioned so that when the tip portion is engaged with the branch artery, the leg of the profiled portion adjacent to the shaft will be parallel to and engaged with the opposing inner wall of the main artery to resist forces tending to displace the tip portion from the branch artery.
