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

    IPC: A61F2/24

    Abstract: A valve holder for delivering a prosthetic heart valve to an implant site is in various embodiments configured to reduce or eliminate the occurrence of suture looping or other damage to the prosthetic valve during implantation. The valve holder can be configured to deploy or actuate automatically when performing preparatory steps that are already familiar to practitioners, such as attaching a delivery handle to the valve holder, so that the valve holders will not require additional steps or training to use. Therefore, operation of the valve holders is kept simple, and occurrences of mistakes caused by user error can be minimized or reduced. Valve holders according to different embodiments can be designed to accommodate implantation of prosthetic heart valves from either the inflow end or the outflow end of the native valve annulus.

    Abstract: A dynamic, adjustable annuloplasty ring sizer can include an adjustable ring replica, which can be adjusted through a range of sizes corresponding to available prosthetic annuloplasty repair ring sizes. Actuation of an adjustment trigger on a handle portion of the ring sizer can displace tension wires that extend through a malleable shaft and through a plurality of articulating segments that form the ring replica. Displacement of the tension wires causes flexion of the joints between adjacent articulating segments, thereby reducing the overall size of the ring replica. Releasing the tension wires can allow an elastic extension wire to act on the ring replica, enlarging the ring replica to its maximum, at-rest size. In this manner, the appropriate size of annuloplasty ring prosthesis can be determined with a single device, without requiring a plurality of static ring sizers that require individual insertion and placement for the conventional trial-and-error sizing methods.
