    摘要: 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.

    摘要: Valve holders and introducers for delivering a prosthetic heart valve to an implant site are in various embodiments configured to facilitate insertion of prosthetic valves through small incisions or access sites on a patient's body. The valve holders can also be configured to reduce or eliminate the occurrence of suture looping or other damage to the prosthetic valve during implantation. A valve holder according to embodiments of the invention includes features that reduce or eliminate mistakes during implantation of the prosthetic valves, such as a removable activator dial and a removable handle that prevent implantation of the valve prior to proper deployment or adjustment of the holder. An introducer is provided which can facilitate passing of a prosthetic valve between adjacent ribs of a patient. Valve holders and introducers according to the various embodiments can be used in minimally invasive procedures, such as thoracotomy procedures.

    摘要: A mitral repair annuloplasty ring that will accommodate implantation of a transcatheter valve therein for a valve-in-ring reoperation. The ring has a semi-rigid core with features that allow the ring to better conform to the cylindrical geometry of a transcatheter valve when implanted. The inner core defines a continuous peripheral D-shape with a substantially straight anterior side diametrically across from a more rounded posterior side with arcuate lateral sides therebetween. Segments of the ring core are subject to differing rates of bending due to variable radial thicknesses or radial slits opening to both inner and outer edges around the core periphery. One or more expansion joints may also be used to create the more circular final expanded shape. A plastically expandable sealing sleeve may surround the transcatheter valve for sealing gaps between the valve and annuloplasty ring.

    摘要: 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.
