Publication number: 20220142694Abstract: A medical device having a catheter and a fluid delivery conduit entirely disclosed within a portion of the catheter. The catheter may have a thermally transmissive region in fluid communication with the fluid delivery conduit and a rod disposed within at least a portion of the fluid delivery conduit. The medical device may control variable fluid flow with the ability to modify the effective cross-sectional area of the fluid delivery conduit available for fluid flow. Additional configurations provided herein may 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.Type: ApplicationFiled: January 27, 2022Publication date: May 12, 2022Inventors: Regina E. GROVES, Jean-Pierre LALONDE, Timothy G. LASKE, Claudia LUECKGE, Dan WITTENBERGER, Ramin SABBAGHE-KERMANI, Mahmoud KABIR-SERAJ

Patent number: 11266457Abstract: 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.Type: GrantFiled: March 15, 2019Date of Patent: March 8, 2022Assignee: Medtronic CryoCath LPInventors: Regina E. Groves, Jean-Pierre Lalonde, Timothy G. Laske, Claudia Lueckge, Dan Wittenberger, Ramin Sabbaghe-Kermani, Mahmoud Kabir-Seraj

Patent number: 11141209Abstract: A method and system for providing lesion depth feedback during an ablation procedure. In particular, the method and system provide feedback data or information relating to lesion depth in myocardial tissue during a cryoablation procedure. A plurality of tissue temperature measurements may be transmitted from a plurality of thermocouples disposed on a cryotreatment element, which measurements may be used to determine a slope of change in temperature sensed by each thermocouple over time. The circulation of coolant through the treatment element may be adjusted when the slope changes. A change in slope may indicate that the cryoablation temperatures have passed through target myocardial tissue into non-target, non-myocardial tissue, which may result in collateral damage to structures near the heart.Type: GrantFiled: September 10, 2018Date of Patent: October 12, 2021Inventors: Jean-Pierre Lalonde, Regina E. Groves, Timothy G. Laske, Paul A. Iaizzo, John C. Bischof
