Publication number: 20240090933Abstract: A cryoablation catheter includes an inner lumen and an inflatable balloon surrounding the inner lumen. An inflow pipe is disposed within the inflatable balloon and is configured to introduce a refrigerant into the balloon. A thermocouple wire is disposed within the inflatable balloon and positioned adjacent the inflow pipe. The thermocouple wire is configured to measure an internal temperature of the balloon. The cryoablation catheter further includes an isolation guide disposed within the inflatable balloon. The isolation guide includes a central bore configured to receive the inner lumen, an inflow bore configured to receive the inflow pope, and a thermocouple bore configured to receive the thermocouple wire. The thermocouple bore is spaced from the inflow bore along the isolation guide.Type: ApplicationFiled: August 17, 2023Publication date: March 21, 2024Inventors: Claire S. Chen, Carlos H. Lima, Leonila Rivera

Patent number: 11622857Abstract: A catheter based balloon enabled prosthetic heart valve delivery device is provided. The balloon enabled delivery device is configured to deploy a prosthetic heart valve through inflation. The balloon enabled delivery device is further configured to reduce or prevent migration of the prosthetic heart valve during deployment. Migration is prevented through a combination of balanced inflation of the balloon, inflation fluid flow balancing structures, retention rings, retention covers, and balloon surface treatments.Type: GrantFiled: June 4, 2020Date of Patent: April 11, 2023Assignee: Medtronic, Inc.Inventors: William Chang, James Mitchell, Leonila Rivera, Siyan Som, Martha Barajas-Torres, Leo Mendoza

Publication number: 20220054264Abstract: Balloon catheters for delivery of prosthetic hear valves is provided. The balloon catheters are configured to deploy a prosthetic heart valve through inflation. The balloon catheters are further configured with one or more retention bumpers to reduce or prevent migration of the prosthetic heart valve during delivery. Balloon catheters described herein are configured with substantially incompressible retention bumpers that promote longitudinal inflation fluid flow.Type: ApplicationFiled: August 19, 2021Publication date: February 24, 2022Inventors: Alan T. MCGUINN, Alistair COURTNEY, Amy L. COMAR, William BERTHIAUME, Conleth MULLEN, David F. LYDON, Declan SILKE, Dmitry SHEREMETIEV, Eoghan TWOHIG, Gavin KENNY, James HANNON, James MITCHELL, Jonathan G.

Patent number: 10512504Abstract: Catheter apparatuses, systems, and methods for achieving renal neuromodulation by intravascular access are disclosed herein. One aspect of the present technology, for example, is directed to a treatment device having a multi-electrode array configured to be delivered to a renal blood vessel. The array is selectively transformable between a delivery or low-profile state (e.g., a generally straight shape) and a deployed state (e.g., a radially expanded, generally spiral/helical shape). The multi-electrode array is sized and shaped so that the electrodes or energy delivery elements contact an interior wall of the renal blood vessel when the array is in the deployed (e.g., spiral/helical) state. The electrodes or energy delivery elements are configured for direct and/or indirect application of thermal and/or electrical energy to heat or otherwise electrically modulate neural fibers that contribute to renal function.Type: GrantFiled: November 29, 2017Date of Patent: December 24, 2019Assignee: Medtronic Ardian Luxembourg S.a.r.l.Inventors: William W. Chang, Justin Goshgarian, Kevin Michael Mauch, Leonila Rivera, Sukyoung Shin, Don H. Tran
