    Abstract: A prosthetic heart valve for implant in a human. The valve includes a wireform with undulating inflow cusps and outflow commissure posts to which flexible leaflets attach and coapt in a flow area. Each leaflet may drape over the top of the wireform in the cusp area, but have tabs that each extend underneath the wireform at the commissure posts to be secured along with a tab of an adjacent leaflet. The prosthetic heart valve may also be a dual-wire wireform, with the leaflets sandwiched therebetween. One wireform may be larger than the other, with the leaflets extending over the smaller wireform. The smaller wireform may have commissures that bend radially outward from the larger wireform to provide structure to which the leaflet tabs attach.

    Abstract: A prosthetic heart valve configured to replace a native heart valve and having a support frame configured to be reshaped into an expanded form in order to receive and/or support an expandable prosthetic heart valve therein is disclosed, together with methods of using same. The prosthetic heart valve may be configured to have a generally rigid and/or expansion-resistant configuration when initially implanted to replace a native valve (or other prosthetic heart valve), but to assume a generally expanded form when subjected to an outward force such as that provided by a dilation balloon or other mechanical expander. An inflow stent frame is expandable for anchoring the valve in place, and may have an outflow end that is collapsible to a limited degree for delivery and expandable post-implant to facilitate a valve-in-valve (ViV) procedure. The hybrid heart valves eliminate earlier structural bands, which both reduces manufacturing time and facilitates a ViV procedure.

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

    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.

    Abstract: The invention is a prosthetic device for improving function of a mitral valve. The device includes a sealing member configured for positioning between mitral valve leaflets. The device also includes an expandable anchor frame configured to be positioned within one or more heart chambers, for maintaining the sealing member at a desired position between valve leaflets. The sealing member reduces mitral regurgitation be filling the gap that can occur between opposing leaflets of a damaged mitral valve, thus restoring proper mitral valve closure.
