    Abstract: A quick-connect heart valve prosthesis that can be quickly and easily implanted is provided. The heart valve includes a substantially non-expandable, non-compressible prosthetic valve and a plastically-expandable coupling stent, thereby enabling attachment to the annulus without sutures. A small number of guide sutures may be provided for aortic valve orientation. The prosthetic valve may be a commercially available valve with a sewing ring with the coupling stent attached thereto. The coupling stent may expand from a conical deployment shape to a conical expanded shape, and may include web-like struts connected between axially-extending posts. A system and method for deployment includes a hollow two-piece handle through which a balloon catheter passes. A valve holder is stored with the heart valve and the handle easily attaches thereto to improve valve preparation steps.

    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 valve-in-valve (ViV) procedures. The hybrid heart valves eliminate earlier structural bands, which both reduces manufacturing time and facilitates ViV procedures.

    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 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.
