    Abstract: A packaged bioprosthetic heart valve comprising a bioprosthetic heart valve, an adaptive seal and a package. The bioprosthetic heart valve comprises an at least partially dehydrated biological tissue leaflet structure coupled to a supporting frame. The bioprosthetic heart valve has a periphery, an inflow portion, and an outflow portion. The adaptive seal is coupled to the bioprosthetic heart valve around at least a portion of the periphery. The adaptive seal comprises an expandable material that expands after exposure to an initiating condition. The bioprosthetic heart valve and the adaptive seal is stored and contained within the package, which does not contain a liquid storage solution in contact with the bioprosthetic heart valve and the adaptive seal.

    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 prosthetic device for treating a native valve of a heart includes a sealing element and an anchoring element. The sealing element comprises a braided mesh material. The sealing element is dimensioned to be deployed at the native valve. The sealing element is configured to both be radially expanded and radially reduced while at a position between the native valve leaflets. The anchoring element is coupled to the sealing element and is configured to support the sealing element between the native valve leaflets.

    Abstract: A prosthetic heart valve configured to replace a native heart valve and for post-implant expansion and having a valve-type indicator thereon visible from outside the body post-implant. The indicator communicates information about the valve, such as the size or orifice diameter of the valve, and/or that the valve has the capacity for post-implant expansion. The indicator can be an alphanumeric symbol or other symbol or combination of symbols that represent information about the characteristics of the valve such as the valve size. The capacity for post-implant expansion facilitates a valve-in-valve procedure, where the valve-type indicator conveys information to the surgeon about whether the implanted valve is suitable for the procedure and informs the choice of the secondary valve.

    Abstract: A hybrid prosthetic heart valve configured to replace a native heart valve and having a support frame configured to be expanded post implant in order to receive and/or support an expandable prosthetic heart valve therein (a valve-in-valve procedure). 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 for delivery and expandable post-implant to facilitate a valve-in-valve procedure.

    Abstract: The invention is a prosthetic device for improving function of a mitral valve. The device includes an adjustable and axisymmetrical-or-elongated 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 and size/shape 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.

    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.
