Abstract
A triple profile balloon catheter has a catheter shaft with an inflation/deflation lumen. A balloon is located at a distal section of the catheter shaft. The balloon has a first segment in a proximal portion of the balloon, and a second segment in a distal portion of the balloon. An intermediate segment with a length greater than 3 mm couples the first and second segments. The first segment has a first average diameter, the second segment has a second average diameter that is less than the first average diameter. The balloon has a single chamber coupled to the inflation/deflation lumen.
