Publication number: 20210251678Abstract: 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.Type: ApplicationFiled: May 6, 2021Publication date: August 19, 2021Inventors: Jean-Pierre LALONDE, Dan WITTENBERGER, Marwan ABBOUD, Constantin Bogdan CIOBOTARU, Ramin SABBAGHE-KERMANI

Patent number: 6589234Abstract: The present invention provides a medical device to cold treat desired regions. An injection tube with an open distal end is disposed inside of a catheter tube, defining a return lumen therein. A supply of cryogenic fluid, regulated by a controller mechanism coupled to the device, flows through the injection tube and into the distal tip portion of the catheter tube, whereupon the fluid is returned from the catheter through the return lumen. The expansion and evaporation of cryogenic fluid inside the device serves to cool the surrounding areas external to and proximate the distal end of the device. An additional restriction tube is provided in the length of the catheter tube to regulate the pressure of the flow of cryogen therethrough so as to create higher operating pressures in the distal end of the device and thereby enhance the cooling power and temperature stability of the device at a lower range of fluid flow rates without reaching the triple point of the cryogenic fluid.Type: GrantFiled: September 27, 2001Date of Patent: July 8, 2003Assignee: CryoCath Technologies Inc.Inventors: Jean-Pierre Lalonde, Marwan Abboud, Constantin Bogdan Ciobotaru
