Abstract: Embodiments of prosthetic valves for implantation within a native mitral valve are provided. A prosthetic valve may comprise a radially compressible main body and a one-way valve portion. The prosthetic valve may further comprise one or more ventricular anchors coupled to the main body and disposed outside of the main body. The ventricular anchors may be configured such that a reduced profile of the prosthetic valve is possible. A space may be provided between an outer surface of the main body and the ventricular anchors for receiving native mitral valve leaflets. The prosthetic valve may include an atrial sealing member adapted for placement above the annulus of the mitral valve. Methods and devices for receiving the native mitral valve leaflets between the ventricular anchors and the main body are described.

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.

Abstract: Valvular implants and blood vessel closure devices herein are configured to be positioned in the heart and to block regurgitant blood flow from the heart into blood vessels supplying blood to the heart. The valvular implants can have a cover, a membrane, a valve, a resilient frame, and/or other features. Some valvular implants can have anchors to be positioned in the blood vessels, such as in pulmonary veins, and can anchor the implant to the heart wall. Various embodiments of covers and/or membranes act as valves contracting and expanding, to alternately permit and block blood flow. The valvular implants can cover one or more blood vessels, such as one, two, three, or four pulmonary veins, and can also be configured and implanted to block an appendage to the heart, such as the left atrial appendage.

Abstract: In one embodiment, a prosthetic valve can comprise a radially expandable and compressible frame, which can include a plurality of struts which are pivotally joined together without requiring individual rivets. In some embodiments, the struts are interwoven, and can be joined using integral hinges formed in the struts, such as by performing alternate cuts on the struts, bending the struts to form stopper tabs adjacent to joints and/or drilling holes in the struts to facilitate interconnecting struts at joints, or otherwise forming integral hinges and corresponding holes at junction points between the struts. In another embodiment, the frame comprises a plurality of inner struts and outer struts which are connected by a plurality of chains of interconnected rivets, avoiding the need to provide individual rivets at each junction between struts. In still another embodiment, separate hinges or flanged rivets are provided to interconnect the struts.

Abstract: Systems and methods usable in delivering a docking device to a native valve of a patient's heart. A distal region of a delivery catheter can be positioned in an atrium of the heart and a distal tip can be positioned at or near a commissure of the native valve. The docking device can be located within the delivery catheter. A pusher, such as a pusher wire or tube, of a pusher tool can be advanced distally through the delivery catheter, wherein the pusher can push the docking device along within the delivery catheter. The docking device can be connected to the pusher tool by a line, such as a suture. A member of the pusher tool can be rotatable to change the amount of the suture extending from the pusher tool.

Abstract: A docking device for docking a prosthetic valve at a native valve of a heart can include a coil comprising a plurality of turns and having a proximal end and distal end. The docking device can further include a first covering disposed around and covering the coil from the distal end to the proximal end of the coil, and a second covering disposed over the first covering. A distal end and proximal end of the second covering are spaced away from a distal end and proximal end, respectively, of the first covering.

Abstract: Methods of implanting docking devices for prosthetic valves at a native heart valve include positioning a distal end of a delivery catheter into a first chamber of a heart, advancing a tubular body of a docking device from within the delivery catheter so that the distal end of the tubular body is advanced between native valve leaflets and positioned in a second chamber of the heart. The methods further include inserting a coil into a lumen of the docking device so that the tubular body adopts a configuration, releasing a proximal end of the docking device in the first chamber, inserting a replacement valve in an inner space of the docking device, and radially expanding the replacement valve until there is a retention force between the replacement valve and the docking device to hold the replacement valve in a stable position in the native valve.
