Patent number: 10828091Abstract: A catheter with a variable circular loop responsive to a contraction wire for coiling is supported by a member having a tapered distal section that transitions from a circular cross-section to a generally rectangular cross-section while maintaining a uniform cross-sectional area along the entire tapered length for improved coiling characteristics. A radially constrictive sleeve prevents separation of the contraction wire from the support member to minimize misshaping of the loop during contraction.Type: GrantFiled: December 28, 2016Date of Patent: November 10, 2020Assignee: BIOSENSE WEBSTER (ISRAEL) LTD.Inventors: Thomas V. Selkee, Jose L. Jimenez

Patent number: 10828102Abstract: An ablation probe is provided. The ablation probe includes a housing that is configured to couple to a microwave energy source. A shaft extends distally from the housing and includes a radiating section at a distal end thereof. A sensor assembly is operably disposed on the housing and includes a pair of sensor contacts. One or more sensors are positioned adjacent the radiating section and extend along the shaft. The sensor(s) have a pair of sensor contact pads that are positioned on the shaft for contact with the pair of sensors such that during transmission of microwave from the radiating section into target tissue at least one electrical parameter is induced into the at least one sensor and detected by the pair of sensor contacts.Type: GrantFiled: February 26, 2018Date of Patent: November 10, 2020Assignee: Covidien LPInventors: James E. Dunning, Eric W. Larson, Jennifer McHenry

Patent number: 10828086Abstract: Methods for treating tissue with irreversible electroporation and immunotherapy are described. The methods include placing a probe in tissue within a human body, wherein the probe has at least a first electrode, applying a plurality of electrical pulses through the first electrode and a second electrode, causing irreversible electroporation (IRE) of the tissue within a target ablation zone, and administering one or more exogenous agents into the tissue within the target ablation zone or to the human, thereby stimulating or otherwise modulating an immune system response within the body.Type: GrantFiled: December 26, 2018Date of Patent: November 10, 2020Inventors: Rafael V. Davalos, John H. Rossmeisl, Paulo A. Garcia

Patent number: 10828089Abstract: A catheter has a two-piece tip electrode with a shell and a support structure that are secured to each other by multiple redundant mechanisms in order to reduce the risk of tip detachment during a procedure. The tip electrode includes at least two different welds attaching the shell to the support structure to provide a dual failure mode. One weld includes a seam weld and another weld includes a penetration weld.Type: GrantFiled: August 2, 2013Date of Patent: November 10, 2020Assignee: BIOSENSE WEBSTER (ISRAEL) LTD.Inventors: Jeffrey L. Clark, Daniel Gonzalez, John Thompson, Ivan Totten

Patent number: 10820920Abstract: A variety of methods for managing a re-usable ultrasonic medical device may include a medical device control module capable of receiving functional data from a user assembled or reassembled ultrasonic medical device, and notifying the user if a value of the functional data lies within an acceptance range. If the value of the functional data does not lie within the acceptance range, the control module may prompt a user to reassemble the device or to clean or replace one or more components thereof. The functional data may relate to a clamp force of a jaw assembly, an impedance or resonant frequency value of an ultrasonic blade, or a mechanical displacement value of one or more moving components of the device.Type: GrantFiled: July 5, 2017Date of Patent: November 3, 2020Assignee: Ethicon LLCInventors: Patrick J. Scoggins, Tylor C. Muhlenkamp, David C. Groene, William D. Dannaher, Benjamin D. Dickerson, Phillip H. Clauda, Rafael J. Ruiz Ortiz, Matthew C. Miller, Kevin A. Bash

Patent number: 10814100Abstract: A deflectable device, such as a catheter, is provided that includes a hinge that enhances the ability of the device to deflect or bend within a predetermined plane. The catheter comprises an elongated tubular catheter body having proximal and distal ends and at least one lumen extending therethrough. A distal segment is provided distal to the distal end of the catheter body. A tubular hinge is provided between the distal end of the catheter body and the proximal end of the distal segment. The hinge has an axis and at least one lumen extending therethrough. The tube includes at least one slot, and preferably a plurality of slots, extending part of the way through the hinge generally transverse to the axis of the hinge.Type: GrantFiled: January 18, 2019Date of Patent: October 27, 2020Assignee: Biosense Webster, Inc.Inventors: Benjamin D. McDaniel, Martin F. O'Sullivan, James K. Lee

Patent number: 10806503Abstract: A method of identifying gaps between electrophysiology (EP) ablation points may comprise: obtaining a plurality of ablation points recorded from a completed electrophysiology ablation procedure; digitally mapping the plurality of ablation points to an anatomical model corresponding to the completed electrophysiology ablation procedure; calculating ablation gap probability distributions for each of the plurality of ablation points based on ablation tolerance variables associated with each of the plurality of ablation points; and overlaying the ablation gap probability distributions on to the digitally mapped plurality of ablation points on the anatomical model. In this way, ablation gaps may be non-invasively identified prior to patient discharge, thereby allowing for further EP treatment to remove the ablation gaps while reducing readmission rates.Type: GrantFiled: February 6, 2017Date of Patent: October 20, 2020Assignee: General Electric CompanyInventors: Adrian F. Warner, Daniel Richard Schneidewend
