Publication number: 20230390058Abstract: Devices and methods for retrieving percutaneously implanted catheter systems such as a heart valve repair system. The devices include at least one locking connector at the distal end of a flexible elongated extension for coupling to an implanted tubular member. The locking connector may be a tubular anchor having a pair of distal prongs which are biased outward and face in a proximal direction, as well as an expandable auxetic midsection. Inserting the tubular anchor into the implanted tubular member flexes the distal prongs inward such that they prevent proximal movement of the tubular anchor. A user pulls on the proximal end of the tubular anchor to expand the auxetic midsection and lock the two pieces together. The devices and methods are particularly useful to attach extensions to implanted concentric tubes to enable relative axial force application.Type: ApplicationFiled: August 8, 2023Publication date: December 7, 2023Inventors: Joseph Arthur Passman, Omar Fawzi Azanki

Publication number: 20230078736Abstract: A delivery system includes a handle, a catheter shaft, and a steering mechanism. The catheter shaft extends from the handle to a flexible distal end portion. The steering mechanism is configured to steer the flexible distal end portion. The steering mechanism can include a steering element a control member, and one or more actuation elements. Actuating the control member can move the steering element to increase and/or decrease tension in one or more actuation elements.Type: ApplicationFiled: November 18, 2022Publication date: March 16, 2023Inventors: Haim Brauon, Or Cohen, Brian Patrick Murphy, Omar Fawzi Azanki, Ernest William Heflin, Steven Eric Decker, Timothy Allen Dalton, Ehud Aviv, Lindsay Marie Hall, Murrad Mirza Kazalbash, Julia Akiko Roche, Danny Barrientos Baldo

Publication number: 20220071620Abstract: An apparatus is provided for use with a tissue anchor and an anchor driver. The apparatus includes a housing, shaped to define a channel. The channel includes (i) an anchor-storage zone, and (ii) a proximal opening configured to provide access for the anchor driver to the anchor-storage zone. The channel is configured to enable sliding of the tissue anchor therewithin to be stored in the anchor-storage zone. The apparatus also includes a retaining member, shaped to define a cradle for cradling and holding the tissue anchor in the anchor-storage zone. The retaining member includes a pillar pivotable with respect to the cradle, and configured to support the tissue anchor at the cradle. Other embodiments are also described.Type: ApplicationFiled: November 17, 2021Publication date: March 10, 2022Inventors: Haim Brauon, Ehud Aviv, Brian Patrick Murphy, Praveen De Silva, Kevin K. Dang, Omar Fawzi Azanki, Tomer Golan, Aaron Anan Ness, Tal Reich, Luis Molina, Sam Shafigh

Patent number: 11007061Abstract: Devices and methods for treating patients with functional tricuspid regurgitation (TR) who are unsuitable for surgery include an interoperative, adjustable-size coapting element on a catheter which may be implanted within the left or right side of the heart and extends upward into the vasculature and out of the body. The radial diameter of the coapting element can be modulated in tandem with electrocardiographic imaging to reduce valve regurgitation. One system has an elongated catheter and an expandable coapting element mounted to a distal end with an auxetic structure connected to opposite end caps. A tensioning mechanism controlled from a proximal end of the catheter is configured to pull apart the two end caps and thus elongate and radially expand the auxetic structure. Other forms of the coapting element are disclosed, as well as a kink-resistant catheter sheath having a triangular cross-section.Type: GrantFiled: May 14, 2019Date of Patent: May 18, 2021Assignee: Edwards Lifesciences CorporationInventors: Joseph Arthur Passman, Omar Fawzi Azanki, Kokou Anani Amefia

Publication number: 20190059876Abstract: Devices and methods for securing a tissue anchor in tissue of a patient, in particular to ensure proper deployment of a cardiac tissue anchor by regulating the force or pressure of a deployment tool against the tissue. One way to ensure proper deployment force is to visualize the distal end of the tissue anchoring catheter from outside the body using a display for an imaging sensor, where the distal end of the catheter changes configuration when it is pressed against the tissue. Another method involves automatically regulating the pressure applied to the tissue prior to deployment of the tissue anchor, which may also be used in conjunction with visualization. Several safety locks to prevent deployment of the tissue anchor prior to establishment of the proper pressure are disclosed, which again may be used with visualization and/or an automated pressure regulator.Type: ApplicationFiled: August 21, 2018Publication date: February 28, 2019Inventors: Steven Eric Decker, Matthew Michael Becerra, Nancy Hoang Khuu, Timothy Allen Dalton, Sue-Lynn Wu, Mark Chau, Omar Fawzi Azanki, Robert C.
