    Abstract: A crimping device for a prosthetic heart valve can comprise an annular outer frame and an inner frame extending through the outer frame, the inner frame comprising first and second axial end portions and a plurality of jaw guides extending therebetween, where the inner frame defines a central opening extending therethrough. The crimping device can comprise a plurality of jaws operatively coupled to the inner and outer frames, each jaw having an inner portion positioned within the central opening of the inner frame and an engagement portion configured to slide along a respective jaw guide, each jaw guide comprising an inclined guiderail extending between the first and second axial end portions. Relative axial motion between the outer and inner frames causes radial motion of the jaws for crimping a prosthetic device positioned within the central opening.

    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: A replacement mitral valve prosthesis includes a support structure and a valve body having three flexible leaflets. The support structure preferably includes an internal valve frame and an external sealing frame. The valve frame supports the flexible leaflets. The sealing frame is adapted to conform to the shape of the native mitral valve annulus. The sealing frame may be coupled to an inlet end of the valve frame, an outlet end of the valve frame, or both. A plurality of anchors is coupled to the outlet end of the valve frame. The anchors extend radially outwardly for placement behind native leaflets. The prosthesis preferably includes a skirt disposed along an exterior of the external sealing frame. The prosthesis is collapsible for delivery into the heart via a delivery catheter. The prosthesis is configured to self-expand for deployment in the heart when released from the delivery catheter.

    Abstract: A coil device for treating a heart valve includes a wire with a distal end and a proximal end with a cloth configured to promote ingrowth of tissue into the cloth covering at least a portion of the wire. The wire is formed at least partially from a memory metal that is pre-shaped to assume a helical coil shape with a diameter designed to provide a constricting force on a ventricle wall of a heart when the coil device is woven behind tissue features of trabeculae carneae associated with the ventricle wall.

    Abstract: An orifice-expanding device for measuring an expanded heart valve. The device includes a proximal handle having a shaft and an orifice-expanding device with a hub mounted to a distal end of the shaft and a plurality of arms evenly spaced around the axis and connected to the hub and extending therefrom in a distal direction to distal ends of the arms. The distal end of each arm has an expanding portion with an outer surface, the expanding portions being configured to move radially outward with respect to each other, wherein expansion of the expanding portions causes the distal ends of the arms to flex outward. A pressure-measuring device measures a pressure applied to the aortic valve annulus, and a size-measuring device measures a dimension of the aortic valve annulus after the annulus has been expanded.

    Abstract: A crimping system for a prosthetic heart valve comprises an elongate rigid body and a radially flexible, tubular sock. The body has an inner lumen extending along a central longitudinal axis between an insertion end and an outlet end. The inner lumen has a greater diameter at the insertion end than at the outlet end. The sock is configured to receive a radially compressible prosthetic heart valve in a radially expanded state within the sock and to pull the valve through the inner lumen of the rigid body from the insertion end to the outlet end with the sock being positioned between an outer surface of the valve and an inner surface of the rigid body. The valve is radially compressed by the inner surface of the rigid body as the sock pulls the valve along the longitudinal axis toward the outlet end of the lumen.
