Patent number: 12029467Abstract: A method and system for creating permanent lesions in an area of target tissue, such as tissue at or proximate a junction between a pulmonary vein and the left atrium. The method may generally include positioning a medical device in contact with a pulmonary vein ostium, ablating the tissue, and recording a plurality of temperature measurements from one or more of three temperature sensors. The device may include an occlusion element in communication with a coolant source, a first sensor located distal of the occlusion element, a second sensor located proximal of the occlusion element, and a third sensor located in the occlusion element. One or more temperature measurements may be compared with each other to assess occlusion of the pulmonary vein, and/or may be compared with a set of reference temperatures to predict a real-time temperature within the target tissue.Type: GrantFiled: November 16, 2021Date of Patent: July 9, 2024Assignee: Medtronic CryoCath LPInventors: Dan Wittenberger, Jean-Pierre Lalonde, Stephen A. Howard

Publication number: 20240016484Abstract: A transseptal system includes a needle, a guidewire, a handle, and a dilator. The handle defines a needle passage to slidably receive the needle, and a guidewire passage to slidably receive the guidewire. The dilator defines a lumen having a distal region and a proximal region. The dilator is coupled to the handle such that the lumen is open to the needle passage and the guidewire passage. The proximal region of the lumen is sized to simultaneously receive the needle body and the guidewire. The distal region is sized to slidably receive one of the needle and the guidewire on an individual basis. A transseptal puncture and access procedure can be performed, including puncturing tissue with the needle followed by immediate advancement of the guidewire into the accessed area, eliminating the need for multiple instrument exchanges during the procedure.Type: ApplicationFiled: September 28, 2023Publication date: January 18, 2024Inventors: Stephen A. Howard, Kevin A. Knutsen
