Abstract
A device, method, and system for thermally affecting tissue. The device may generally include an elongate body, an actuation element slidably disposed within the elongate body, a balloon defining an interior chamber, a proximal neck, and a distal neck, the first neck being coupled to the distal portion of the elongate body and the second neck being coupled to the distal portion of the actuation element, retraction of the actuation element within the elongate body causing the treatment element to transition from a first configuration to a second configuration. The distal neck may be located external to the interior chamber in the first configuration and within the interior chamber in the second configuration. The device may also include a fluid injection element that is transitionable to an expanded configuration when the balloon is inflated, thereby enhancing the cooling capacity of the balloon.
