    Abstract: A system for expanding a device in a conduit or orifice of a human body includes a balloon member that is movable from a first configuration to a second configuration. External surfaces of the balloon member can collectively have a non-cylindrical cross-section relative to a main axis of the balloon member, such that the external surfaces of the balloon member generally conform to the anatomical shape of the conduit or orifice when the balloon member is in the second configuration.

    Abstract: Systems, and methods for treating valvular regurgitation, prolapse, and other valve problems are described. Some embodiments include occluding and/or obstructing devices that traverse an annulus, some implementations anchor an occluding device via a coil. Some implementations provide systems and methods to bring native leaflets in closer proximity to each other to prevent valvular problems. Some embodiments provide outflow-side solutions that encircle chordae tendineae, while some implementations provide inflow-side solutions via joined tissue anchors that can be cinched together.

    Abstract: A prosthetic apparatus for implantation in a native mitral valve includes a main body for placement within the native mitral annulus. The main body is compressible to a radially compressed state for delivery into the heart and is self-expandable from the compressed state to a radially expanded state for implantation. A valve structure is mounted within a lumen of the main body and preferably forms three leaflets made of pericardium. An atrial sealing member is disposed along an atrial portion of the main body and ventricular anchors are coupled to a ventricular portion of the main body. The atrial sealing member impedes the flow of blood between the main body and the native annulus. The ventricular anchors are positioned outside the main body for capturing native mitral valve leaflets between the main body and the ventricular anchors.

    Abstract: A method of implanting a prosthetic mitral valve assembly using a transapical procedure is disclosed. An incision is formed in the chest in the apex of the patient's heart. A delivery catheter containing the prosthetic mitral valve assembly is advanced over a guidewire into the patient's heart. The prosthetic mitral valve assembly is deployed from the delivery catheter into the native mitral valve. The prosthetic mitral valve assembly comprises a stent having a lower portion for placement between the leaflets of a native mitral valve and an upper portion having a flared end for placement above the annulus. The prosthetic mitral valve includes a valve portion having leaflets formed of pericardial tissue. A plurality of upwardly bent prongs are provided along an outer surface of the stent for preventing upward migration of the prosthetic mitral valve assembly after deployment.

    Abstract: A heart valve prosthesis that can be quickly and easily implanted during a surgical procedure is provided. The prosthetic valve has a base stent that is deployed at a treatment site, and a valve component configured to quickly connect to the base stent. The base stent may take the form of a self- or balloon-expandable stent that expands outward against the native valve with or without leaflet excision. The valve component has a non-expandable prosthetic valve and a self- or balloon-expandable coupling stent for attachment to the base stent, thereby fixing the position of the valve component relative to the base stent. The prosthetic valve may be a commercially available to valve with a sewing ring and the coupling stent attaches to the sewing ring. The system is particularly suited for rapid deployment of heart valves in a conventional open-heart surgical environment. A catheter-based system and method for deployment is provided.
