  • Patent number: 11963870
    Abstract: A method of replacing a native heart valve utilizing a support structure comprising a first fastener, a second faster, a first leaflet brace, and a second leaflet brace. The first leaflet brace is configured to be advanced over a first guide wire to be adjacent to a portion of a first native leaflet. The second leaflet brace is configured to be advanced over a second guide wire to be adjacent to a portion of a second native leaflet. The first fastener and the second fastener are configured to be advanced over the first and second guide wires to respectively engage with first and second ends of the first leaflet brace and the second leaflet brace. A replacement heart valve is deployed within the native heart valve, thereby capturing the first and second leaflets between the support structure and the replacement heart valve.

  • Publication number: 20240057987
    Abstract: An implant comprises an elongate member, and anchors distributed along the elongate member. A gripper comprises a locking element that, in a locked state thereof, inhibits sliding of the elongate member through the gripper by clamping the elongate member. A tool is configured to, while (i) the elongate member extends proximally from a proximal-most of the anchors, and through the gripper, and (ii) an unlocker is positioned within the gripper in a manner that obstructs the locking element from assuming the locked state: (A) advance transluminally toward the proximal-most anchor, and (B) tension the elongate member by pulling the elongate member proximally through the gripper while the unlocker obstructs the locking element from assuming the locked state. The tool is also configured to subsequently facilitate the locking element clamping the elongate member via withdrawal of the unlocker from the gripper. Other embodiments are also described.

  • Patent number: 11832784
    Abstract: 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.

  • Patent number: 11576784
    Abstract: An active annuloplasty ring holder having a template that can be folded or pivoted to the side allowing the template to align longitudinally with the handle and enter the patient's chest through a small incision. The holder may include a mechanism to remotely detach sutures fastening the ring to the holder, thereby detaching the ring while avoiding the risk associated with introducing a scalpel into the operating field. A detachment mechanism may include a movable pin actuated by a pull wire that releases a plurality of holding sutures, or a hot wire, knives, or pull wire that severs the sutures. The holder may have a built-in light source for better visualization of the ring inside the heart. The holder may also have an optical means of visualizing the inside of the heart from the proximal end of the handle.

  • Patent number: 11478351
    Abstract: Embodiments of a heart shape preserving anchor are disclosed herein. The heart shape preserving anchor can include a frame having one or more wings extending from a lower end of the frame. The frame can be sized and shaped to distribute forces over a large surface area thereby reducing pressures applied on the heart. The anchor can include a tether for coupling to a prosthesis, such as a replacement heart valve prosthesis. In some embodiments, the anchor can include a tether adjustment mechanism which can be wirelessly operated to adjust a length of the tether relative to the frame.

  • Publication number: 20220211497
    Abstract: A two-stage or component-based valve prosthesis that can be quickly and easily implanted during a surgical procedure is provided. The prosthetic valve comprises a support structure that is deployed at a treatment site. The prosthetic valve further comprises a valve member configured to be quickly connected to the support structure. The support structure may take the form of a stent that is expanded at the site of a native valve. If desired, the native leaflets may remain and the stent may be used to hold the native valve open. In this case, the stent may be balloon expandable and configured to resist the powerful recoil force of the native leaflets. The support structure is provided with a coupling means for attachment to the valve member, thereby fixing the position of the valve member in the body. The valve member may be a non-expandable type, or may be expandable from a compressed state to an expanded state.

  • Publication number: 20220176076
    Abstract: A steerable catheter comprises a flexible tube having a proximal portion and a distal portion and comprising a circumferential wall that defines an elongate lumen between the proximal portion and the distal portion. A pull-wire can extend, in association with the wall, from the proximal portion to the distal portion. A pull-ring can be coupled to the wall at the distal portion such that the pull-ring circumscribes the lumen, and coupled to the pull-wire, such that pulling on the pull-wire bends the distal portion. The pull ring can have (i) a first state in which the pull-ring is elliptical and has a first eccentricity, and (ii) a second state in which the pull-ring is elliptical and has a second eccentricity that is smaller than the first eccentricity. The pull ring can be biased toward the first state, and deformable to the second state. Other embodiments are also described.

  • Patent number: 11224507
    Abstract: A heart valve prosthesis for replacing a native mitral valve includes a self-expanding frame with a plurality of anchoring members disposed along the lower region. A valve body is positioned within the self-expanding frame and includes a plurality of leaflets configured to allow blood flow through the self-expanding frame in only one direction. A skirt surrounds the self-expanding frame and is spaced apart therefrom for contacting surrounding tissue and impeding blood flow around the self-expanding frame. The skirt may be reinforced with wires to help maintain a desired shape. The leaflets in the valve body are preferably connected to the self-expanding frame through one or more intermediate components such that the valve body is spaced radially inwardly from an inner surface of the self-expanding frame.

  • Patent number: 11135062
    Abstract: Methods, systems, and apparatuses for treating a heart are provided. Methods can include obtaining and using an implant. One or more catheters can be used to properly position and attach the implant in a desired location in a chamber of the heart, for example, on a ventricular wall of the left ventricle between one or more papillary muscles of the left ventricle and the annulus. Then a distance along the implant or a region of the heart, for example, between the papillary muscle and the annulus, can be reduced by contracting the implant along its longitudinal axis by applying tension to a contraction member of the implant. Other embodiments are described.
