Patent number: 11938317Abstract: Energy is transmitted to a body lumen or passageway in the form of pulsed electric fields (PEFs) and in a manner which provides focal therapy. In some embodiments, PEFs are delivered through independent electrically active electrodes of an energy delivery body, typically in a monopolar fashion. Such delivery concentrates the electrical energy over a smaller surface area, resulting in stronger effects than delivery through an electrode extending circumferentially around the lumen or passageway. It also forces the electrical energy to be delivered in a staged regional approach, mitigating the effect of preferential current pathways through the surrounding tissue. Focal delivery of PEFs can provide increased tissue lethality by employing precise timing and sequencing of energy delivery to the electrodes.Type: GrantFiled: December 7, 2022Date of Patent: March 26, 2024Assignee: Galvanize Therapeutics, Inc.Inventors: William Sanford Krimsky, Paul Brian Friedrichs, Roman Turovskiy, Robert E.

Patent number: 11896284Abstract: A catheter and patch electrode system is provided for use with an apparatus, such as an ablation generator, having a 4-wire interface for improved impedance measurement. The 4-wire interface includes a pair of source connectors across which an excitation signal is produced and a pair of sense connector wires across which the impedance is measured. The RF ablation generator may also produce an ablation signal across a source wire and an indifferent return patch electrode. The system further includes a cable that connects the generator to a catheter. The catheter includes a shaft having a proximal end and a distal end, with an ablation tip electrode disposed at the distal end. A source lead is electrically coupled to the tip electrode and extends through the shaft to the proximal end where it is terminated. An optional sense lead is also electrically coupled to the tip electrode and extends through the shaft to the proximal end. The system further includes a source return (e.g.Type: GrantFiled: April 17, 2020Date of Patent: February 13, 2024Assignee: St. Jude Medical, Atrial Fibrillation Division, IncInventors: Stephan P.

Patent number: 11896780Abstract: A catheter having a catheter shaft that has a more uniform construction throughout a length of the catheter shaft and is able to provide more than one deflection curvature. The catheter shaft includes a flexible outer tubular member, and a less flexible inner tubular member extending through the outer tubular member in a proximal section of the catheter shaft, wherein the inner tubular member is afforded longitudinal movement relative to the outer tubular member. The catheter also includes at least one puller wire extending through the inner tubular member to deflect a distal deflection section of the catheter shaft, wherein the longitudinal movement of the inner tubular member relative to the outer tubular member enables an operator to select and set a deflection curvature of the distal deflection section.Type: GrantFiled: January 11, 2021Date of Patent: February 13, 2024Assignee: BIOSENSE WEBSTER (ISRAEL) LTD.Inventors: Christopher Thomas Beeckler, Rowan Olund Hettel

Patent number: 11896281Abstract: A cryo-fixation lead extraction device includes a lead extraction catheter having longitudinally spaced proximal and distal catheter ends and an elongate catheter lumen. A liner has longitudinally spaced proximal and distal liner ends and an elongate liner lumen. The liner lumen is configured to selectively accept at least part of a lead being extracted longitudinally therethrough. At least a portion of the liner is located circumferentially within and/or circumferentially surrounding the catheter lumen. At least one cryogen supply line extends longitudinally through at least a portion of the liner lumen. The cryogen supply line is configured to place a cryogen fluid source into fluid communication with the distal liner end. The cryogen supply line is configured to selectively generate a patient tissue cooled zone adjacent the distal catheter end. A method of cryo-fixation lead extraction is also provided.Type: GrantFiled: November 9, 2018Date of Patent: February 13, 2024Assignees: THE CLEVELAND CLINIC FOUNDATION, CPSI HOLDINGS LLCInventors: Oussama Wazni, Marwane Berrada-Sounni, John M.

Patent number: 11896294Abstract: Methods and systems for ablating target tissue, such as in or along an airway, include modulation one of power and current of an a system to achieve a treatment output or parameter. Treatment outputs can include current, power, energy delivered, percent drop in impedance, an impedance-based ratio, a percent impedance slope, and/or an airway wall impedance. Power and/or current of the system can be varied, within certain maximum thresholds, such as power, current, and/or impedance thresholds, to achieve the desired output parameter target during some or all of the treatment time. The systems and methods reduce the variability of the treatment efficacy otherwise due to variability in electrical properties of patient tissue and/or electrode contact.Type: GrantFiled: December 7, 2017Date of Patent: February 13, 2024Assignee: Nuvaira, Inc.Inventors: Philip J. Johnson, Ryan Kaveckis, Martin L. Mayse

Patent number: 11890190Abstract: A catheter, advanced toward an anatomical site, has a proximal end and a steerable distal end. An anchor is advanced through the catheter. An anchor driver drives the anchor out of the catheter's distal end, anchoring the anchor at the site. A first constraining member engages tissue, and inhibits, after the anchor has been driven out of the catheter and before the anchoring, movement of at least the anchor driver's distal end, on a first axis between the anchor driver's distal end and a site at which the first constraining member engages the tissue. A second constraining member inhibits, after the anchor has been driven out of the catheter and before the anchoring, movement of at least the anchor driver's distal end, on a second axis. Other embodiments are also described.Type: GrantFiled: April 27, 2020Date of Patent: February 6, 2024Assignee: Edwards Lifesciences Innovation (Israel) Ltd.Inventors: Tal Sheps, Tal Hammer, Tal Reich, Ehud Aviv, Amir Gross, Yaron Herman, Alexei Koifman, Yuval Zipory

Patent number: 11890185Abstract: A system and method for performing an ocular surgical procedure is provided. The design maintains IOL temperature prior to implantation by assessing a desired IOL temperature, sensing existing IOL temperature, and maintaining the IOL substantially at the desired IOL temperature based at least in part on said existing IOL temperature. The method of maintaining desired IOL temperature involves comparing current IOL temperature with pre-established desired temperature conditions to determine a temperature change. The IOL is maintained substantially at the desired temperature based at least in part on the existing IOL temperature.Type: GrantFiled: April 22, 2011Date of Patent: February 6, 2024Assignee: Johnson & Johnson Surgical Vision, Inc.Inventors: Mark S Cole, Kevin R Springer, Rob Raney
