Publication number: 20210244362Abstract: Methods and systems of catheterization include a flexible catheter adapted for insertion into a heart of a living subject. The catheter has a lumen for passing an electrically conductive fluid therethrough, which is propelled by a peristaltic pump. A fluid reservoir connected to the lumen supplies the fluid to the catheter. Electrocardiogram circuitry is connectable to the subject for monitoring electrical activity in the heart. An electrically conductive cable diverts induced charges in the fluid from the catheter electrodes, for example by shorting to a rotating element in the peristaltic pump.Type: ApplicationFiled: April 26, 2021Publication date: August 12, 2021Inventors: John Hardy ASHTON, George KAMIN, Jose G. RAMOS

Patent number: 10524858Abstract: This disclosure is directed to a catheter having a dual node multiray electrode assembly at the distal end of the catheter body. The dual node multiray electrode assembly includes a proximal multiray array with a plurality of spines connected at one end, each spine having at least one ablation electrode, and a distal node. The dual node multiray electrode assembly may have an expanded configuration and a collapsed configuration wherein the spines are arranged generally along a longitudinal axis of the catheter body. The distal node may be configured to be deployed within a vessel and the proximal multiray array may be configured to engage tissue forming an ostium of the vessel with the ablation electrodes. In some embodiments, the relative distance between the proximal multiray array and the distal node is adjustable.Type: GrantFiled: December 9, 2015Date of Patent: January 7, 2020Assignee: BIOSENSE WEBSTER (ISRAEL) LTD.Inventors: Ryan Hoitink, John Hardy Ashton, Jeffrey L. Clark, Mario A. Solis, Shubhayu Basu
