Abstract:
1. A medical device, comprising: an injection lumen; an exhaust lumen; a thermally conductive element defining a chamber, the chamber being in fluid communication with the injection lumen and the exhaust lumen; a thermally conductive support element located entirely within the exhaust lumen proximal to the chamber; a first temperature sensor mounted on the support element; a second temperature sensor positioned in the chamber, the first and second temperature sensors being electrically isolated from each other and having a common ground; and a controller in electrical communication with the first and second temperature sensors, the controller being programmed to detect the presence of a leak in the injection lumen based on at least one of: temperature discrepancies between the first and second temperature sensors and electrical impedance between the first and second temperature sensors, the controller also being programmed to modify coolant flow through the medical device based on the detected presence of a leak.
