Abstract
A perfusion dilatation balloon catheter is formed by a balloon having opposing intermediate chamber surfaces connected by a seal along the length of the balloon to form two symmetrical, communicating segments of the balloon. The outer surface of the balloon, which is common to both segments, incurves as the balloon is inflated causing the segments to juxtapose. The outer surfaces of the two segments cooperate to dilate the wall of an artery. The outer surfaces of the segments further define two sinuses adjacent to the juxtaposed outer surfaces of the segments, which allow passive perfusion of blood through the balloon during a dilatation procedure.
