Patent number: 10966783Abstract: An electrophysiology catheter has a distal electrode section having a generally-cylindrical, hollow housing body, a lumen and an opening in a sidewall. A flex circuit has a first portion supported on the outer surface the housing body, and a second portion that extends into the lumen via the opening for connection to cables and/or wires in the lumen. The flex circuit has a first and second magnetic field sensing coil traces generally perpendicular to each other and a magnetic field sensing coil wire generally perpendicular thereto is wound around the housing body to form an x/y/z position sensor. One or more ring electrodes are carried on the housing body, separated by ring spacers. A force sensor is mounted on a distal end of the housing body, with strain gauges electrically connected to the flex circuit. The housing is configured to provide a distal anchor for a puller tensile.Type: GrantFiled: March 19, 2018Date of Patent: April 6, 2021Assignee: BIOSENSE WEBSTER (ISRAEL) LTD.Inventor: Jeffrey William Schultz

Patent number: 10966784Abstract: An energy applicator for directing energy to tissue includes a feedline having an inner conductor, an outer conductor and a dielectric material disposed therebetween, and an antenna assembly having a radiating section operably coupled to the feedline. The energy applicator also includes a first balun structure configured to substantially confine energy to the radiating section when the energy applicator is energized and disposed in tissue, and a second balun structure configured to substantially prevent energy emitted from the radiating section from propagating proximal to the second balun structure along the feedline when the energy applicator is energized but not disposed in tissue.Type: GrantFiled: February 12, 2018Date of Patent: April 6, 2021Assignee: Covidien LPInventors: Joseph D. Brannan, Joseph A. Paulus

Patent number: 10966785Abstract: Apparatuses and methods are disclosed for applying laser energy having desired pulse characteristics, including a sufficiently short duration and/or a sufficiently high energy for the photomechanical treatment of skin pigmentations and pigmented lesions, both naturally-occurring (e.g., birthmarks), as well as artificial (e.g., tattoos). The laser energy may be generated with an apparatus having a resonator with the capability of switching between a modelocked pulse operating mode and an amplification operating mode. The operating modes are carried out through the application of a time-dependent bias voltage, having waveforms as described herein, to an electro-optical device (e.g., a Pockels cell) positioned along the optical axis of the resonator.Type: GrantFiled: October 14, 2020Date of Patent: April 6, 2021Assignee: Cynosure, LLCInventors: Rafael Armando Sierra, Mirko Mirkov, Richard Shaun Welches

Patent number: 10966786Abstract: A method for performing a medical procedure, includes coupling a tip of a probe to tissue in an organ of a patient in order to apply the medical procedure using the probe. A force exerted by the tip on the tissue and a displacement of the tip created by the force are measured. A dependence of the force on the displacement is calculated. Based on the calculated dependence, a risk level of perforation of the tissue is estimated.Type: GrantFiled: July 27, 2017Date of Patent: April 6, 2021Assignee: Biosense Webster (Israel) Ltd.Inventors: Doron Moshe Ludwin, Eitan Peri, Eyal Yechezkel Glottmann, Yevgeny Bonyak, Aharon Turgeman

Patent number: 10966787Abstract: This invention relates to Patient-Specific Templates (PST) which have already been used by implant manufacturers and clinically applied by orthopedic surgeons. This work presents an apparatus comprised of a unit acquiring data from the surface of bones and joints, a computerized unit for surgical planning and a desktop 3D printer for manufacturing PST, which are functionally, physically and electrically connected. The apparatus is compact, portable and suitable for hospital-based or clinic-based service. The data-collection unit has electro-magnetic (EM) device, diagnostic ultrasound machine, laser scanner and a receiver for acquisition of external data. It integrates the data from multiple sources and has sensor fusion ability. The surgical planning unit has specific software program capable of merging the collected data through mathematical model of specific parts of bones, joints and a library of implants and prostheses.Type: GrantFiled: April 26, 2016Date of Patent: April 6, 2021Inventor: Mahmoud Alm El Din Hafez

Patent number: 10966788Abstract: The subject matter includes a system and method for providing graphical feedback visualizing forces within a joint through a range of motion of the joint. The method can comprise receiving position data, receiving force data, and generating a graphical representation based on the position data and the force data. The receiving position data can include data for at least one bone of a joint while the at least one bone is moved through a range of motion (ROM). The receiving force data can occur concurrently to receiving the position data and using one or more processors, the force data can be collected from at least one force sensor embedded within a trial prosthesis in the joint. The graphical representation can illustrate changes in the force data versus locations of the bone as it moved through the ROM.Type: GrantFiled: December 13, 2018Date of Patent: April 6, 2021Assignee: Zimmer, Inc.Inventors: Orsa Britton, David A.

Patent number: 10966790Abstract: A processing system comprises a processor and a memory having computer readable instructions stored thereon. The computer readable instructions, when executed by the processor, cause the system to obtain a reference tree of nodes and linkages based on a reference three dimensional volumetric representation of a branched anatomical formation in a reference state. The computer readable instructions also cause the system to obtain a reference three dimensional geometric model based on the reference tree and detect deformation of the branched anatomical formation due to anatomical motion based on measurements from a shape sensor. The computer readable instructions also cause the system to obtain a deformed tree of nodes and linkages based on the detected deformation and create a three dimensional deformation field that represents the detected deformation of the branched anatomical formation.Type: GrantFiled: November 12, 2019Date of Patent: April 6, 2021Assignee: INTUITIVE SURGICAL OPERATIONS, INC.Inventors: Prashant Chopra, Vincent Duindam, Lei Xu, Tao Zhao
