Abstract
There is disclosed a balloon catheter wherein the balloon is fabricated of a high pressure, ultra-thin wall modified polyethylene terephthalate copolymer, and has a desired memorized shape. In a preferred embodiment the balloon has a central waist-like configuration suitable for valvuloplasty. The polymer can be heat-shaped and retains or memorizes a desired shape thereafter. The balloon is blow-molded and attached to a catheter for inflation through a lumen thereof. When inflated to a first low pressure it assumes the desired shape, and rounds out after a second inflating pressure is achieved.
