摘要： A cardiac implant system including a cardiac implant such as an annuloplasty ring, a prosthetic heart valve, or a valved conduit pre-assembled at the time of manufacture with devices for securing the implant to a heart valve annulus using knotless suture fasteners. The knotless suture fasteners may be embedded within a pliant sealing edge of the cardiac implant, or they may be positioned adjacent to the sealing edge. The knotless suture fasteners are spring-biased so as to grip onto annulus anchoring sutures pass to therethrough upon removal of a restraining device, such as a hypotube inserted within the suture fasteners. Guide tubes are assembled in line with the suture fasteners to permit introduction of suture snares that pass through the suture fasteners and through the sealing edge to facilitate capture of the pre-installed annulus anchoring sutures.

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.

摘要： A prosthetic heart valve has a plurality of valve leaflets that control directional flow of blood through a heart and a stent structure having a plurality of commissure posts supporting the valve leaflets. The stent structure has a covering over the plurality of commissure posts and has a sewing ring at an inflow end of the stent structure. Each of the plurality of commissure posts has a tip and a suture loop is attached to the covering at a location adjacent to or on the tip of the commissure post. Each suture loop provides a passage for a suture to pass through between the covering and the suture loop.

摘要： A prosthetic heart valve holder system includes a prosthetic heart valve having a base at an inflow end, a plurality of commissure posts extending from the base toward an outflow end, and valve leaflets secured to the commissure posts to permit flow through the heart valve. A deflector is provided at the outflow end having a central hub and a plurality of arms extending from the central hub secured to and covering the tips of respective commissure posts. A valve support body is secured to the base and a post connects the valve support body to the hub of the deflector. The plurality of arms are sufficiently collapsible such that, in a first position, free ends of the arms are located axially between the hub and the valve support body to prevent suture looping during an implant procedure, and in a second position, the hub is located axially between the free ends of the arms and the valve support body to permit removal of the deflector from the outflow side of the valve, through the valve leaflets, to the inflow side of the valve.

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.

摘要： Systems, apparatuses, and methods disclosed herein are provided for medical treatment, including treatment of dilated hearts (e.g., dilated left ventricle) or functional mitral valve regurgitation within a human heart. In instances, transcatheter medical treatments may be utilized. The portion of the patient's heart may be dilated due to a myocardial infarction or other cardiomyopathy. The treatment may comprise beating-heart repair of left ventricles with ischemic or non-ischemic dilated cardiomyopathy. The treatments may include approximating papillary muscles of the heart.

摘要： An annuloplasty ring for repair of mitral and tricuspid valves that can be shape adjusted once installed to fine-tune the shape and correct for small errors in the inherently imprecise sizing process. The ring has an adjustable 3D ring core of malleable metal that can be reshaped in real-time during the procedure before or after the patient is weaned off-pump by applying simple displacements to a cable and housing arrangement. The shape of the annuloplasty ring is adjusted incrementally in steps until an optimum level of regurgitation reduction is attained. Once the surgeon is satisfied with the result, the delivery system can be can easily detached from the implant and removed. The thickness of the core could be continuously variable to control how and where deformation occurs. The ring may also incorporate an expansion joint to enable a subsequent valve-in-ring procedure.
