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.

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. Interlocking members or flexible loops are included to limit expansion of the valve to one or two valve sizes, for example, with a 2-mm gap between each valve size. The valve may include an internal structural band with overlapped free ends having structure for limiting expansion, or external loops of suture may be added to the fabric covering which limits expansion.

Abstract: Sensor-integrated prosthetic valves that can comprise a variety of features, including a plurality of valve leaflets, a frame assembly configured to support the plurality of valve leaflets and define a plurality of commissure supports terminating at an outflow end of the prosthetic valve, a sensor device associated with the frame assembly and configured to generate a sensor signal, for example, a sensor signal indicating deflection of one or more of the plurality of commissure supports, and a transmitter assembly configured to receive the sensor signal from the sensor device and wirelessly transmit a transmission signal that is based at least in part on the sensor signal.

Abstract: A heart valve sizer and sizer cover are provided for determining the size of a heart valve annulus. The valve sizer can include a handle, a shaft extending distally from the handle, a sizing element coupled to the distal end of the shaft, the sizing element being movable between a first retracted position and a second expanded position, and a sizer cover. The sizer cover can be formed from a continuous sheet of material configured to surround at least a portion of the sizing element of the heart valve sizer so as to guard against entanglement of the sizing element with structures of a human heart.

IPC: A61F2/24

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.
