    摘要: Systems, apparatuses, and methods disclosed herein are provided for medical treatment, including transcatheter medical treatments and/or for treatment of dilated hearts (e.g., dilated left ventricle) or functional mitral valve regurgitation within a human heart. The systems, apparatuses, and methods disclosed herein may include applying one or more heart splints to the patient's heart to apply pressure to the heart to reshape the heart. Anchors disclosed herein may be utilized in plugs for treating openings in a septum between two chambers of a heart, e.g., ventricular septal defects (VSD), atrial septal defects (ASD), and patent foramen ovale (PFO). In addition, the anchors disclosed herein may be utilized to reshape an annulus of a patient's heart valve, including a tricuspid valve of a patient's heart. The anchors disclosed herein may also be utilized to reposition a heart valve leaflet to reduce heart valve leaflet prolapse.

    摘要: 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.

    摘要: A prosthetic heart valve can include a valve frame having a wireform portion and a stent portion. The wireform and stent portions can be undetachably coupled together via a plurality of upright struts so as to form a one-piece prosthetic heart valve frame. Alternatively, a self-expanding wireform portion and a balloon-expandable stent portion can be coupled together via one or more leaflets and a subassembly having a flexible leaflet support stent and a sealing ring. The wireform portion can include cusps and commissures configured to support a plurality of leaflets. The prosthetic valve can be radially collapsible for minimally invasive and/or transcatheter delivery techniques. Disclosed embodiments can also provide flexion of the wireform portion (e.g., of the commissures) in response to physiologic pulsatile loading when the valve is implanted in a patient's native valve annulus. Methods of making and using prosthetic heart valves are also disclosed.

    摘要: A hybrid prosthetic heart valve configured to replace a native heart valve and having a support frame configured to be expanded post implant in order to receive and/or support an expandable prosthetic heart valve therein (a valve-in-valve procedure). 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 for delivery and expandable post-implant to facilitate a valve-in-valve procedure.

    摘要: 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.

    摘要: 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.
