Publication number: 20180036079Abstract: The catheter allows mapping and/or ablation of the area around two or more PV ostia at the same time, with a single placement of a distal section of the catheter having a 2D configuration resembling an infinity or lazy 8 symbol. The catheter has an elongated catheter body, a distal section having at least a flexible elongated member with shape memory, the member being configured to assume a 2D configuration resembling an infinity symbol, and at least one electrode mounted on the member. The 2D configuration resembles a first loop and a second loop, wherein the first and second loops are side-by-side, generally extending in a common plane.Type: ApplicationFiled: October 16, 2017Publication date: February 8, 2018Inventors: Ryan Hoitink, Shubhayu Basu

Patent number: 9820664Abstract: A catheter adapted or high density mapping and/or ablation of tissue surface has a distal electrode matrix having a plurality of spines arranged in parallel configuration on which a multitude of electrodes are carried in a grid formation for providing uniformity and predictability in electrode placement on the tissue surface. The matrix can be dragged against the tissue surface upon deflection (and/or release of the deflection) of the catheter. The spines generally maintain their parallel configuration and the multitude of electrodes generally maintain their predetermined relative spacing in the grid formation as the matrix is dragged across the tissue surface in providing very high density mapping signals. The spines may have free distal ends, or distal ends that are joined to form loops for maintaining the spines in parallel configuration.Type: GrantFiled: November 20, 2014Date of Patent: November 21, 2017Assignee: Biosense Webster (Israel) Ltd.Inventors: Ryan Hoitink, Curt R. Eyster, Stuart Williams, Meir Bar-Tal, Shobhayu Basu, Shamim Qutubuddin

Publication number: 20170100189Abstract: A catheter for ablating tissue is disclosed that has a self-centering multiray electrode assembly. The self-centering multiray electrode assembly may have a plurality of spines, each of which a preshaped, expanded configuration that curves to change an orientation of the spine from being directed towards the distal end of catheter body to being directed towards the proximal end of the catheter body. The ablation electrodes engage ostial tissue when a maximal outer diameter of the self-centering multiray electrode assembly is engaged with an inner diameter of a vessel. The compliance of each spine may vary along its length. When the self-centering multiray electrode assembly is engaged within a vessel, the ablation electrodes are brought into contact with tissue and may be used to form lesions in a circumferential path around the vessel.Type: ApplicationFiled: October 13, 2015Publication date: April 13, 2017Inventors: Jeffrey CLARK, John ASHTON, Ryan HOITINK, Jeffrey SCHULTZ
