    摘要： A stent for use in a prosthetic heart valve has a plurality of expandable and collapsible closed cells, a portion of which form an annulus section adapted for placement within the annulus of the native heart valve. Anchor features of the stent residing within at least some closed cells are adapted to engage tissue of the heart, including native valve leaflets, the sinotubular junction, or another implanted device when the prosthetic valve is implanted in the heart. The anchor features may help to retain the prosthetic valve in position, without interfering with the opening and closing of the valve leaflets. Furthermore, the anchor features may be configured to allow the stent to be resheathed into a delivery device after the portion of the stent with the anchor feature has expanded out of the delivery device.

    摘要： A prosthetic heart valve is designed to be circumferentially collapsible for less invasive delivery into the patient. At the implant site the valve re-expands to a larger circumferential size, i.e., the size that it has for operation as a replacement for one of the patient's native heart valves. The valve includes structures that, at the implant site, extend radially outwardly to engage tissue structures above and below the native heart valve annulus. These radially outwardly extending structures clamp the native tissue between them and thereby help to anchor the prosthetic valve at the desired location in the patient.

    摘要： A prosthetic heart valve includes a balloon-expandable stent including a plurality of struts and a plurality of commissure posts, each commissure post containing an elongated slot. A plurality of leaflets is made from pericardial tissue and includes flaps. An intermediate polymer sheet is disposed between the stent and the plurality of leaflets. At least one reinforcing polymer core is attached to at least one leaflet and the intermediate polymer sheet using stitches that loop around an end of the at least one leaflet. A plurality of patches covers the elongated slots of the commissure posts, the flaps of the leaflets being attached to the patches. A cuff contacts an exterior of the stent, the cuff and the intermediate polymer sheet sutured to one another so as to cover an axial end of the stent.

    摘要： A delivery device for a collapsible prosthetic heart valve includes a support shaft around which a compartment for the valve is defined, a distal sheath adapted to selectively cover and uncover the compartment and the valve, and a marker cage having a collapsed condition when the distal sheath covers the compartment and an expanded condition when the compartment is uncovered. The marker cage includes at least one rib having a radiopaque marker for determining the positioning of the valve as it is deployed. The valve may be assembled around the marker cage so that the marker cage does not interfere with the radial expansion of the valve during deployment.

    摘要： Apparatus for use with a prosthetic heart valve includes a holder, to which the heart valve is releasably attached, and an elongated handle. The handle can be connected to the holder simply by pushing a distal end of the handle straight into a recess in the holder. After this has been done, the holder preferably releasable latches onto the handle, and the handle can also be rotated about its longitudinal axis to transmit torque to the holder (e.g., a rotatable portion of the holder). Rotation of such a rotatable portion of the holder can be used to deflect portions of the valve radially inward. This operation of a rotatable portion of the holder is preferably one-way-only. The handle can be released from the holder at any time, and it can similarly be reconnected to the holder at any time.

    摘要： An annuloplasty prosthesis for a heart valve has a sewing cuff added to the conventional structure. The sewing cuff is preferably an extension of the fabric cover that is provided around the core of the prosthesis. The sewing cuff preferably extends radially outwardly from cross sections of the remainder of the prosthesis. Methods of making such a sewing cuff are also disclosed.
