  • Patent number: 11974914
    Abstract: Prosthetic heart valves and anchors for use with such valves are provided that allow for an improved implantation procedure. In various embodiments, an anchoring device is formed as a coiled or twisted anchor that includes one or more turns that twist or curve around a central axis. One or more arms attached to the frame of the valve guide the anchoring device into position at the native valve as it exits the delivery catheter, and the expandable prosthetic valve is held within the coil of the anchoring device. The anchoring device and the valve can be delivered together, simplifying the valve replacement procedure.

  • Patent number: 11951000
    Abstract: An implant and method for repairing and/or replacing functionality of a native mitral valve are in various embodiments configured to reduce or eliminate mitral regurgitation and residual mitral valve leakage. A coiled anchor can be used to implant a prosthetic valve in a native mitral valve of a heart. The coiled anchor can include a plurality of ventricular turns and one or more atrial turns. The coiled anchor is configured to be implanted at the native mitral valve with the plurality of ventricular turns positioned in a left ventricle of the heart and around valve leaflets of the native mitral valve. The plurality of ventricular turns are configured such that when a radially outward pressure is applied to at least one of the plurality of ventricular turns, the coiled anchor is biased such that a first diameter of a first turn of the plurality of ventricular turns is expanded and a second diameter of a second turn of the plurality of ventricular turns is reduced.

  • Publication number: 20230329866
    Abstract: Apparatus for treating blood flow regurgitation through a native heart valve includes a selective occlusion device sized and configured to be implanted in the native heart valve and selectively operating with at least one of the first or second native leaflets to allow blood flow through the native heart valve when the heart cycle is in diastole and reduce blood flow regurgitation through the native heart valve when the heart cycle is in systole. A clip structure is coupled with the selective occlusion device. The clip structure is configured to be affixed to a margin of at least one of the first or second native leaflets to secure the selective occlusion device to the native heart valve.

  • Patent number: 11779508
    Abstract: Systems and methods described herein include a pressure delivery component that has a pressure applicator configured to selectively apply therapeutic pressure to a treatment portion of a user body, and also includes a thermal delivery component that has a thermal applicator that is a configured to apply thermal treatment to the treatment portion. The thermal applicator may be removably disposable in operative relationship with the pressure delivery component in a use configuration of the treatment delivery component such that the thermal applicator is disposable between the treatment portion and the pressure applicator when the treatment delivery component is disposed on the treatment portion in the use configuration. Moreover, the pressure applicator is operable to apply pressure to the thermal applicator to enhance apposition of the thermal applicator to the treatment portion.

  • Publication number: 20230264017
    Abstract: Disclosed are various configurations of electrodes with accompanying extensions and wires configured to be attached at or near the left atrium of a heart to allow the device to be held snug against the endocardium and out of the blood flow for low energy defibrillation of the atria in response to atrial fibrillation or other atrial arrhythmias. The portion of the lead internal to the atrium (e.g., the left atrium) is restrained against the endocardium of the left atrium by way of a restraint mechanism. In one example, the electrode is configured to attach to the atrial septum, with wires containing memory-shaped metal to keep the wires against the heart wall. In yet another example, the electrode is configured to be part of a mitral valve device.
