The present invention provides a medical system, including a catheter defining an injection lumen, a chamber in fluid communication with the injection lumen, and an exhaust lumen in fluid communication with the chamber; a first temperature sensor positioned in the exhaust lumen proximal to the chamber; a second temperature sensor positioned in the chamber; and a console in electrical communication with the first and second temperature sensors, the controller modifying coolant flow through the medical device based at least in part upon a signal received from the first and second temperature sensor. The system may further include a thermally-conductive element circumscribing a substantial portion of the exhaust lumen proximal to the chamber, where the first temperature sensor is mounted to the thermally-conductive element, and the thermally-conductive element may include at least one of a braid, coil, and band.

Thermocouple-controlled catheter cooling system

Systems and methods for controllably variable fluid flow are disclosed that provide the ability to modify the effective cross-sectional area of the fluid delivery conduit available for fluid flow. Accordingly, selective control of these configurations allows fluid flow to be regulated as desired while the fluid delivery pressure remains the same. Additional configurations provided herein allow for the selective manipulation of a footprint or therapeutic pattern achievable with the medical device during a single procedure, negating the need for the removal and insertion of multiple devices to achieve the same variations in treatment geometry or characteristics.
