  • Patent number: 10195026
    Abstract: Disclosed herein are prosthetic devices and related methods for implantation at the native mitral valve of the heart by drawing an atrial portion and a ventricular portion toward each other from opposite sides of the native mitral valve, clamping the native mitral valve therebetween. One or more retention members passing through the mitral valve orifice or through a puncture in the native valve anatomy can couple the atrial and ventricular members together and keep them anchored onto the native mitral valve anatomy. The atrial portion can seat against the atrial side of the mitral annulus while the ventricular portion can include hooks and/or a sub-annular ring that engage and capture the native mitral valve apparatus to provide anchorage. The described technology can avoid the need to use sutures to anchor a prosthetic device at the mitral valve region.

  • Patent number: 10076413
    Abstract: Systems and methods treat a heart valve using a magnetically adjustable annuloplasty ring attached to or near a cardiac valve annulus. A changing magnetic field may be used to selectively increase or decrease a circumference of, or otherwise modify the shape of, the implanted annuloplasty ring. The adjustable annuloplasty ring includes a tubular body member, one or more adjustable members, and an internal magnet within the tubular body member. The tubular body member and the one or more adjustable members form a ring shape. The internal magnet is configured to rotate in response to a rotating external magnetic field. The internal magnet is coupled to the one or more adjustable members to change a dimension of the ring shape as the internal magnet rotates. A system for treating a heart valve may include an external adjustment device having one or more external magnets to generate the rotating external magnetic field.

    Abstract: The present teachings provide devices and methods of treating a tricuspid valve regurgitation. Specifically, one aspect of the present teachings provides devices and methods of identifying a suitable location on the tricuspid annulus, placing a wire across the tricuspid annulus at such an identified location, deploying a tissue anchor across such an identified location, deploying two or more tissue anchors and coupling the tissue anchors with a flexible tensioning member, and applying tension to a flexible tensioning member that is coupled with the two or more tissue anchors, plicating tissues between each pair of the two or more tissue anchors, and reducing the circumference of the tricuspid annuls. As a result, a regurgitation jet is reduced or eliminated.

  • Patent number: 9993339
    Abstract: Devices and methods are described for treating a mitral valve defect. The device described includes features that allow the device to conform to the actual pathology of the valve, rather than attempting to replicate a healthy valve (which the patient does not have). In this way, the device allows the patient's actual value to work as well as possible, given the valve's diseased condition. The actual pathology of the valve is accommodated by providing for multiple dimensions of adjustability of the device, including adjustability of the size (e.g., diameter) of the device as well as adjustability of the elevation or inclination of one portion of the device (e.g., the portion supporting the posterior leaflet) with respect to another portion of the device.
