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.

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; anda balloon attached to the elongate member and adapted to move between a deflated configuration and an inflated con
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; anda 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. 2. The medical device of claim 1, wherein the elongate member body defines an infusion lumen; and further comprising a second balloon attached to the elongate member and adapted to move between a deflated configuration and an inflated configuration, the second balloon positioned over a portion of the balloon and comprising a second balloon proximal end, a second balloon distal end, and a second balloon wall that defines a pore and an infusion chamber in communication with the infusion lumen, the pore extending through the second balloon wall and providing access to the infusion chamber. 3. The medical device of claim 2, wherein the second balloon proximal end is attached to the balloon distal to the articulating region. 4. The medical device of claim 1, wherein the articulating region comprises a portion of the balloon that has been processed with a solvent or bombarded with an ion beam. 5. The medical device of claim 1, wherein the articulating region comprises at least one of a restraining band or a stent disposed about the circumference of the balloon. 6. The medical device of claim 1, wherein the articulating region comprises a corrugated region that defines a plurality of ridges. 7. The medical device of claim 1, wherein the elongate member body defines an inflation port, a first opening in communication with the inflation lumen, and a second opening in communication with the inflation lumen, the first opening defined on the inflation port, the second opening defined between the balloon distal end and the articulating region. 8. The medical device of claim 7, wherein the elongate member body defines a third opening in communication with the inflation lumen, the third opening defined between the second opening and the balloon proximal end. 9. The medical device of claim 1, wherein the balloon is formed of a material that has a rated burst pressure between about 15 ATM and about 30 ATM. 10. The medical device of claim 1, wherein the balloon is formed of a textile balloon. 11.
