ABSTRACT:
A balloon dilatation catheter for use in percutaneous transluminal coronary angioplasty has a balloon having proximal and distal segments in which the proximal segment of the balloon is smaller in diameter than the distal segment. The catheter is adapted for use in the "kissing balloon" technique. The smaller diameter proximal sections reduce the distension of the common artery and bifurcation where the kissing balloon technique is utilized.
