A first expandable element may be coupled to the elongate body, where the first expandable element is in fluid communication with the injection lumen and the exhaust lumen. Further, a perfusion path may be disposed within the elongate body, and a sheath may be movably disposed about at least a portion of the elongate body. The medical device may further include a second expandable element disposed about the elongate body, as well as second inflation and exhaust lumens.
