Publication number: 20240122708Abstract: An annuloplasty structure includes a contracting member. A fastener is configured to receive the contracting member therethrough, the fastener including a housing and a clamping structure disposed therein. The fastener has an open state in which the contracting member can pass through the fastener, and is biased toward assuming a closed state in which the clamping structure clamps onto the contracting member disposed through the fastener. A stop is coupled to the fastener in a manner that maintains the fastener in the open state. A tool includes static and dynamic cutting elements, and is configured to (a) apply tension to the contracting member by pulling the contracting member proximally through the fastener, (b) lock the tension in the contracting member by pulling the stop proximally out from the fastener, and (c) sever the contracting member by moving the dynamic cutting element. Other embodiments are also described.Type: ApplicationFiled: December 21, 2023Publication date: April 18, 2024Inventors: Haim Brauon, Tal Sheps, Aviv Galon, Rafael Pintor

Publication number: 20240115383Abstract: A tubular system is configured to transluminally deliver an implant comprising a tissue anchor having a coupling head and a distal helical tissue-engaging element, into a heart of a subject. The tissue anchor is slidable through a channel of the system, the channel being slidable within a catheter. An anchor driver is configured, while coupled to the coupling head of the tissue anchor, to drive the tissue anchor through the system and out the system's distal end, to anchor the tissue-engaging element to tissue of the heart. While a first electrode is in contact with the subject and a second electrode is inside the heart of the subject, a control unit receives an electrophysiological signal from the electrodes, and based on the electrophysiological signal, indicates a position of the second electrode inside the heart. Other embodiments are also described.Type: ApplicationFiled: December 20, 2023Publication date: April 11, 2024Inventors: Tal Sheps, Tal Hammer, Tal Reich, Ehud Aviv, Amir Gross, Yaron Herman, Alexei Koifman, Yuval Zipory

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.

Patent number: 11890191Abstract: A method for use with a heart of a subject includes advancing a tool distally along a flexible elongate contracting member, toward an anchor implanted at the heart. Tension is applied to the contracting member such that the contracting member slides proximally through a fastener disposed at the heart while a stop coupled to the fastener maintains the fastener in an open state. Using the tool, the stop is pulled proximally (i) away from the fastener, such that the fastener responsively clamps to the contracting member, thereby locking the tension in the contracting member, and (ii) against a cutting element of the tool such that the cutting element moves in a manner that severs the contracting member. Other embodiments are also described.Type: GrantFiled: September 17, 2021Date of Patent: February 6, 2024Assignee: Edwards Lifesciences Innovation (Israel) Ltd.Inventors: Haim Brauon, Tal Sheps, Aviv Galon, Rafael Pintor

Patent number: 11832784Abstract: An annuloplasty implant comprises an elongate member, a plurality of anchors, and a gripper. The elongate member has a proximal end, and a distal portion that includes a distal end. The plurality of anchors are distributed along the elongate member. The elongate member extends proximally from a proximal-most anchor and through the gripper. The gripper comprises a locking element that, in a locked state, inhibits sliding of the elongate member through the gripper. An unlocker, disposed within the gripper, obstructs the locking element from assuming the locked state, and is pullable proximally out of the gripper. The gripper automatically assumes the locked state upon the unlocker being pulled proximally out of the gripper. A tool tensions the distal portion of the elongate member by pulling the elongate member proximally through the gripper while the unlocker obstructs the locking element from assuming the locked state. Other embodiments are also described.Type: GrantFiled: November 13, 2020Date of Patent: December 5, 2023Assignee: Edwards Lifesciences Innovation (Israel) Ltd.Inventors: Tal Sheps, Yaron Keidar, Yuval Zipory
