  • Patent number: 12279956
    Abstract: Catheter apparatuses and methods are provided for repairing heart valves, particularly mitral valves. The method includes providing a catheter having an elongate, flexible body, with a proximal end and a distal end. The distal end can be transluminally advanced from the left atrium through the mitral valve. A distal anchor zone or portion coupled with the proximal end can extend and along the left ventricular outflow tract into the ascending aorta. A valve repair device is deployed to permanently connect leaflets at a mid-section of a mitral valve while permitting medial and lateral portions of the natural leaflets to open and close. The catheter apparatuses may be positionable using a steering device. The valve repair device detachably connects the distal and proximal ends of the catheter. The valve repair device can be detached using low profile devices actuatable from the proximal or distal ends, e.g., at a venous or arterial access site.

  • Publication number: 20240277468
    Abstract: A heart valve prosthesis including separable ventricular and members is provided. The ventricular member has a first hub that has a connection feature. Each of at least three arms are coupled at a first end to the first hub and have a second end opposite the first end. The arms are preloaded toward a location of heart valve leaflet when the ventricular member is implanted. The atrial member has a second hub coupled to a frame array and has a connection feature configured to couple to the connection feature of the first hub for securing the atrial and ventricular members together. The frame array is preloaded toward a location of the heart valve leaflets when the atrial member is implanted. Concavities are formed at the periphery of the frame array to receive the arms of the ventricular member in an engaged configuration. Valve tissue may be trapped between the arms and the concavities.
