Abstract: A valve sizer for determining an appropriate replacement valve size when performing a heart valve replacement procedure is provided. In one version the valve sizer has a hollow shaft with proximal and distal ends. A movable sizing element couples to the distal end of the shaft and is radially expandable between first, contracted and second, expanded positions. An actuator assembly on a handle includes an actuator coupled to a clutch member via a ball-spring-detent clutch. A rod extends through the shaft and maintains a fixed distance between the handle and a distal hub in the sizing element. Movement of the actuator causes axial movement of the shaft, thereby causing radial expansion of sizing petals relative to the hub. The clutch slips when a predetermined reaction force from the surrounding valve annulus is met by the petals.

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.

Abstract: Methods of deploying knotless suture locking clamps for securing prostheses such as heart valves or annuloplasty rings to facilitate implantation. The clamps have opposed clamp halves separated by a slot opening to one side and surrounded by a biasing member such as one or more C-clip springs. Sutures pass laterally into the slot which is held open by a retention member positioned between the clamp halves. The locking clamp slides along the sutures into position, the tension of the sutures is adjusted, and the retention member removed to allow the biasing member to clamp the sutures between the clamp halves. A delivery tool used to deliver and deploy the locking clamps contains a number of clamps within a delivery tube in a stack and bonded together for safety and a common retention member. The tool has a longitudinal channel on one side for entry of sutures.

Abstract: Disclosed herein is a prosthetic heart valve, and associated methods therefore, 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. The prosthetic heart valve is configured to have an 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. 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.

Abstract: A method comprises inserting a needle into a ventricle of a heart. The needle is configured to deliver a first anchoring element, a second anchoring element, and a tethering suture to the ventricle. The tethering suture is tethered between the first anchoring element and the second anchoring element. The method further comprises penetrating a first leaflet of a heart valve with the needle, penetrating a second leaflet of the heart valve with the needle, deploying the first anchoring element at a distal side of the second leaflet, retracting the needle from the first leaflet and the second leaflet, deploying the second anchoring element at a proximal side of the first leaflet, cinching the tethering suture to cause a desired amount of valve coaptation, and locking the tethering suture.

Abstract: A minimally-invasive annuloplasty ring for implant at a mitral annulus. The annuloplasty ring has an inner core member with a C-shaped plan view that generally defines an oval with a major axis and a minor axis, and is symmetric about the minor axis. A posterior portion of the core member bisected by the minor axis has a thicker radial dimension than a pair of free end regions terminating on an anterior side of the core member. The radial thickness smoothly transitions between the posterior portion and the end regions. The inner core member may be covered with a fabric, and is a superelastic metal so that it can be straightened out and delivered through an access tube. The curvatures and thicknesses around the core member are selected so that the strain experienced when straightened does not exceed 7-8%.

Abstract: An annuloplasty band having a differentiation in area moment of inertia, where the area moment of inertia in the out of plane direction is much less than the area moment of inertia in the plane of the annulus. This makes the band stiff enough to hold the annulus in the correct shape while being flexible enough out of plane to minimize the risk of suture dehiscence or breakage. One example is a C-shaped band with a core formed of nitinol and having a constant cross-section with a wider radial dimension than an axial dimension. The cross-section may be rectangular. The band is asymmetric across a minor axis with one end extending around the anterior side farther than the other. The free ends rise up from adjacent lateral sides, and a continuous posterior mid-section also rises upward.

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: Valve holders and introducers for delivering a prosthetic heart valve to an implant site are 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 handle that prevents implantation of the valve prior to proper deployment or adjustment of the holder. An introducer is provided which can facilitate temporary deformation of a nitinol prosthetic valve to pass between adjacent ribs of a patient without rib spreading. Valves are provided having a wireform and stiffener band made of materials that exhibit superelastic properties. Valve holders, introducers, and valves according to the various embodiments can be used in minimally invasive procedures, such as thoracotomy procedures.
