1. A medical device comprising:
- an elongate member having an elongate member proximal end, an elongate member distal end, and an elongate member body that defines an inflation lumen; and
a balloon attached to the elongate member and adapted to move between a deflated configuration and an inflated configuration, the balloon comprising a balloon proximal end, a balloon distal end, an articulating region disposed between the balloon proximal end and the balloon distal end, a proximal portion extending from the balloon proximal end to the articulating region, a distal portion extending from the articulating region to the balloon distal end, and a balloon wall that defines an inflation chamber in communication with the inflation lumen, the articulating region configured to provide articulation between the proximal portion and the distal portion of the balloon, the articulating region formed of a first material, the proximal portion formed of a second material, and the distal portion formed of a third material, the first material being relatively more rigid than the second material and the third material.

Abstract
Articulating balloon catheters and methods of using articulating balloon catheters are described herein. An embodiment of an articulating balloon catheter comprises an elongate member and a balloon. The balloon is attached to the elongate member and is adapted to move between a deflated configuration and an inflated configuration. The balloon has a proximal portion, a distal portion, and an articulating region disposed between the proximal portion and the distal portion. The articulating region of the balloon is configured to provide articulation between the proximal portion and the distal portion of the balloon.
