The angle orientation of the HF electrode relative to the hollow shaft is adjustable in a controlled manner to a working position in which the HF electrode, protrudes radially beyond an outer circumference of the hollow shaft in order to ablate tissue. In the working position, by means of suitable adjustment of the shaft and of the HF electrode, a position can always be found in which the distal end of the HF electrode sufficiently reaches or touches tissue portions that are to be ablated in the region of the bladder neck.Type: GrantFiled: August 30, 2018Date of Patent: March 8, 2022Assignee: KARL STORZ SE & CO. KGInventors: Oliver Löffler, Stefan Rehbein, Uwe Wittke, Frank Doll, Rainer Hermle, Udo Nagele

Patent number: 11241203Abstract: For position sensors, e.g., a fiber-based system, that build a shape of an elongated member, such as a catheter, using a sequence of small orientation measurements, a small error in orientation at the proximal end of the sensor will cause large error in position at distal points on the fiber. Exemplary methods and systems are disclosed, which may provide full or partial registration along the length of the sensor to reduce the influence of the measurement error. Additional examples are directed to applying selective filtering at a proximal end of the elongated member to provide a more stable base for distal measurements and thereby reducing the influence of measurement errors.Type: GrantFiled: November 26, 2019Date of Patent: February 8, 2022Assignee: Auris Health, Inc.Inventors: Sean P. Walker, Serena H. Wong, June Park, Neal A. Tanner

Delivery system and methods for reshaping a heart valve annulus, including the use of magnetic tools
Patent number: 11154400Abstract: Delivery systems, methods and associated devices to facilitate delivery and deployment of a heart implant. Such delivery systems and methods of delivery include use of a pair of magnetic catheters, including an anchor delivery catheter carrying an anchor, which can be stacked with or can be axially offset from the magnetic head. Such systems further include use of a puncturing guidewire advanceable through the magnetic head of the anchor delivery catheter to establish access to a chamber of a heart and which is attached to a bridging element such that continued advancement of the guidewire draws a bridging element attached to the first anchor across the chamber of the heart while the bridging element remains covered by the magnetically coupled catheters. Methods and devices herein also allow for cutting and removal of a bridge element of a deployed heart implant.Type: GrantFiled: August 6, 2018Date of Patent: October 26, 2021Assignee: MVRx, Inc.Inventors: Timothy R. Machold, David R. Tholfsen -
Patent number: 11123185Abstract: Embodiments of the present disclosure provide a delivery apparatus for a prosthetic heart valve. Disclosed delivery apparatuses can include a housing, a steerable shaft, a slide nut, and a threaded shaft disposed over the slide nut. The slide nut can have an external threaded surface and an internal surface comprising a slot. The threaded shaft can have an internal threaded surface engaging the external threaded surface of the slide nut. The delivery apparatus can further include an elongated nut guide extending into the slot of the nut to restrain the slide nut against rotation relative to the housing, and a pull wire having a proximal end portion extending into the housing and coupled to the slide nut, and a distal end portion coupled to a distal end portion of the steerable shaft. The threaded shaft can be rotatable relative to the housing to produce axial movement of the slide nut within the threaded shaft.Type: GrantFiled: September 8, 2020Date of Patent: September 21, 2021Assignee: Edwards Lifesciences CorporationInventors: Philippe Marchand, David M. Taylor, Robert Milich, David J. Evans, Christopher Chia, Ronaldo C. Cayabyab, Robert Bowes

Patent number: 11116387Abstract: An insertion device includes an insertion portion in which a movable member is held in contact with an outer circumferential surface of a hollow cylindrical member. When drive power is transmitted from the hollow cylindrical member to the movable member as the hollow cylindrical member is rotated about a longitudinal axis of the insertion portion, the movable member is rotated around its own axis parallel to the longitudinal axis and moved around the longitudinal axis. The insertion portion includes a membrane covering the movable member from an outer circumferential side thereof. The membrane urges the movable member toward the longitudinal axis, thereby pressing the movable member against the outer circumferential surface of the hollow cylindrical member.Type: GrantFiled: December 4, 2018Date of Patent: September 14, 2021Assignee: OLYMPUS CORPORATIONInventor: Yutaka Masaki
