Publication number: 20230284957Abstract: An apparatus includes two or more medical systems and a low impedance path. The two or more medical systems have respective electrical outputs and respective separate isolation grounds each isolated from power lines and from earth ground, wherein the two or more medical systems are electrically coupled one with the other via the patient. The low impedance path connects the separate isolation grounds of the medical systems to one another, causing one or more leakage currents to flow via the low impedance path instead of via the patient.Type: ApplicationFiled: February 1, 2023Publication date: September 14, 2023Inventors: Yevgeny Bonyak, Roman Inzelbuh, Michael Levin, Elia Wasserman, Omer Ovadia Hury Dror, Pesach Susel

Patent number: 11382530Abstract: In a flexible catheterization probe a resilient member couples the tip to the distal portion of the probe and is configured to deform in response to pressure exerted on the tip when engaging tissue. A position sensor in the distal portion of the probe senses the position of the tip relative to the distal portion of the probe. The relative position changes in response to deformation of the resilient member. The position sensor generates a signal indicative of the position of the tip responsively to a magnetic field produced by a magnetic field generator located in the position sensor. The position sensor has a first coil of conductive wire having first windings, and three second coils of conductive wire having respective second windings. The second coils are symmetrically distributed about the longitudinal axis of the first coil.Type: GrantFiled: July 8, 2019Date of Patent: July 12, 2022Assignee: Biosense Webster (Israel) Ltd.Inventors: Yevgeny Bonyak, Dror Shlomo Levy, Doron Moshe Ludwin, Eitan Moshe Saba, Meir Bar-Tal

Patent number: 10932876Abstract: A haptic feedback device receives a signal reflecting pressure exerted by a medical tool against an anatomical surface. A fastener secures the feedback device to, for example, a wrist of an operator. A haptic exertion component exerts haptic stimulation to the operator based on the received signal such that when the received signal reflects a pressure being exerted by the medical tool against the anatomical surface of a patient is in a defined range for operation of the medical tool, the exertion component exerts haptic stimulation at a predetermined level that indicates pressure of the medical tool is being exerted in the defined range. Otherwise, the exertion component does not exert a level of haptic stimulation that is equal to or more than the predetermined level or the exertion component exerts a level of haptic stimulation to the operator that is more than the predetermined level.Type: GrantFiled: August 30, 2018Date of Patent: March 2, 2021Assignee: Biosense Webster (Israel) Ltd.Inventors: Dror Shlomo Levy, Yevgeny Bonyak, Boris Ashkinezer, Oleg Dulger, Doron Moshe Ludwin, Moshe Ingel
