DIRECTIONAL EXPANSION OF INTRALUMINAL DEVICES
First Claim
Patent Images
1. An expandable medical device comprising:
- a balloon catheter comprising a balloon having a resilient material with a thickness that varies along the length of said balloon, wherein a first section along the length of the balloon comprises thinner balloon material thereby providing lesser resistance to expansion, and a second section along the length of the balloon comprises thicker balloon material thereby providing greater resistance to expansion;
said balloon having a proximal end, a distal end, and a central section, wherein said balloon is configured for controlled, intraluminal, directional expansion within the lumen of a blood vessel.

Abstract
Methods and devices useful, for example, in the field of angioplasty and stenting are disclosed. In some embodiments, the methods, devices and kits are configured for directional expansion inside a lumen, for example of a blood vessel obstructed by plaque. In some embodiments, the directional expansion displaces the plaque in a desired direction.
