    Abstract: A prosthetic device includes a main body, a first anchor, a second anchor, a first anchor spreader, and a second anchor spreader. The first anchor is coupled to the main body such that a spring force of the first anchor biases the first anchor toward the main body. The second anchor is coupled to the main body such that a spring force of the second anchor biases the second anchor against the main body. The first anchor spreader is coupled to the first anchor such that applying a force to the first anchor spreader moves the first anchor away from the main body against the spring force of the first anchor. The second anchor spreader is coupled to the second anchor such that applying a force to the second anchor spreader moves the second anchor away from the main body against the spring force of the second anchor.

    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 apparatus configured for implantation in the native mitral valve region of the heart includes a main body that is self-expandable from a compressed state to a radially expanded state. The prosthetic apparatus comprises at least one ventricular anchor coupled to the main body and disposed outside of the main body for capturing a native valve leaflet between the anchor and an outer surface of the main body. In one preferred method of implantation, the prosthetic apparatus is rotated within the native mitral valve region such that a portion of the anchor moves horizontally behind adjacent chordae for anchoring the prosthetic apparatus in the native mitral valve.

    Abstract: This disclosure pertains generally to prosthetic devices and related methods for helping to seal native heart valves and prevent or reduce regurgitation therethrough, as well as devices and related methods for implanting such prosthetic devices. In some cases, a spacer having a single anchor can be implanted within a native heart valve. In some cases, a spacer having dual anchors can be implanted within a native heart valve. In some cases, devices can be used to extend the effective length of a native heart valve leaflet.

    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.
