1. A medical device for thermally affecting tissue comprising:
an elongate body;
a shaft disposed in the elongate body; and
a treatment element including an atraumatic distal surface, the distal surface being a substantially continuous surface, wherein the treatment element includes
a first inflatable element defining a first chamber and having a first proximal neck and a first distal neck, the first proximal neck being coupled to the elongate body to form a first proximal seal and the first distal neck being coupled to the shaft to form a first distal seal; and
a second inflatable element defining a second chamber and having a second proximal neck and a second distal neck, the second proximal neck being coupled to the elongate body to form a second proximal seal at a location that is proximal to the first proximal seal and the second distal neck being coupled to the shaft to form a second distal seal, at least a portion of the first distal neck being in contact with at least a portion of the second distal neck, wherein the first proximal seal is axially aligned with the second proximal seal along an exterior of the elongate body.
