Treatment of Vascular Bifurcations
First Claim
1. Apparatus for treatment of a vascular bifurcation, where a first blood vessel meets a second blood vessel, the apparatus comprising a balloon for deployment at the vascular bifurcation, the balloon comprising:
- a first part, which has a first inflation characteristic and is adapted to be deployed in the first blood vessel; and
a second part, which has a second inflation characteristic, different from the first inflation characteristic, and is adapted to be deployed in the second blood vessel.

Abstract
Apparatus for treatment of a vascular bifurcation, where a first blood vessel (24) meets a second blood vessel (26). The apparatus includes a balloon (40, 90) for deployment at the vascular bifurcation. The balloon includes a first part (42, 94), which has a first inflation characteristic and is adapted to be deployed in the first blood vessel, and a second part (44, 92), which has a second inflation characteristic, different from the first inflation characteristic, and is adapted to be deployed in the second blood vessel.
