摘要： A catheter is provided comprising a flexible heat transfer element provided on an outer surface of the catheter, a conduit arranged to supply an inflation fluid for inflating the flexible heat transfer element so as to form an inflated balloon, a guide wire lumen for receiving a guide wire, and an elongate cooling element arranged to cool said inflation fluid for inflating the balloon. Said cooling element and said guide wire lumen are arranged inside the flexible heat transfer element such that, when inflated the cooling element is substantially central within the balloon and said guide wire lumen is parallel to and radially offset from the cooling element.
