Embodiments of a prosthetic heart valve are disclosed. An implantable prosthetic valve can include an annular frame having an inflow end, an outflow end and a central longitudinal axis extending from the inflow end to the outflow end. The valve can include a valvular structure including two or more leaflets, each of the two or more leaflets having a leaflet inflow edge positioned at least partially outside of the frame and a leaflet outflow edge positioned within the frame, wherein at least a portion of each of the leaflet inflow edges is unsupported by the frame.

In a representative embodiment, a method comprises implanting first and second inflatable bodies within an annulus of a native heart valve by securing the inflatable bodies to tissue of the native heart valve with sutures, and implanting a prosthetic heart valve between the inflatable bodies such that the prosthetic heart valve is retained within the annulus by the inflatable bodies.

Various aspects of the present disclosure are directed toward apparatuses, systems, and methods for cardiac device anchoring and more specifically to accessing and anchoring in the pericardial space.

A mitral valve system comprising a first docking component and a second valvular component that are delivered via a single delivery catheter. The first component is located distal to the second component and provides a detachable rail to allow the second component to accurately position and lock with the first component. The first component has fixation members that are activated by either by a torus balloon or via fiber that does not restrict blood flow during delivery or during fixation member activation.

A repair assembly and a repair assembly implantation device are provided. The repair assembly comprises a first implant, a second implant, and a wire clamping device; the first implant and the second implant each comprises a first fastener, a second fastener, a transverse tube and a locking wire; the first fastener and the second fastener are connected to the transverse tube by means of connecting wires, and the locking wire is connected to the transverse tube; the wire clamping device is configured to clamp the locking wire.

An exemplary valve repair device for repairing a native valve of a patient includes a coaption element, a pair of paddles, and barb portions. The barb portions extend directly from at least one of the coaption element and the pair of paddles.

An artificial heart valve includes a frame, one or more struts attached to the frame, and a leaflet configured to open and close a fluid flow path through the frame by moving in response to heartbeats. Movement of the leaflet is restricted by the one or more struts. The leaflet includes an inner leaflet body having a negative Poisson's ratio, and an outer leaflet body at least partially surrounding the inner leaflet body, the outer leaflet body having a positive Poisson's ratio.

Embodiments of the present disclosure include a cardiac device comprising a band configured for deployment within a heart. The band may include a first end and a second end, an actuatable clasp associated with the first end of the band and configured to transition, upon actuation, from an open configuration to a closed configuration for forming the band into a fixed length loop after the second end is moved beyond the clasp. The clasp may be configured for actuation via a catheter. The cardiac device may include a clasp retainer associated with the clasp, the clasp retainer being configured to hold the clasp in the open configuration and the clasp being configured to be actuated upon movement of the clasp retainer, and a clasp actuator configured to move the clasp retainer thereby actuating the clasp.

A distal end of a guide catheter is transvascularly advanced into a left ventricle of a heart of a subject. While the distal end of the guide catheter remains disposed in the left ventricle, a first tissue anchor of an implant is deployed from the distal end of the guide catheter. Subsequently, the guide catheter is retracted while progressively exposing the implant. Subsequently, a second tissue anchor of the implant is anchored to a posterior annulus of a mitral valve of the heart by deploying at least part of the second anchor within a left atrium of the heart, such that the implant extends from the first tissue anchor, over an atrial side of a posterior leaflet of the mitral valve, and to the second tissue anchor. Other embodiments are also described.

A ringless web is configured to repair heart valve function in patients suffering from degenerative mitral valve regurgitation (DMR) or functional mitral valve regurgitation (FMR). In accordance with various embodiments, a ringless web can be anchored at one or more locations below the valve plane in the ventricle, such as at a papillary muscle, and one or more locations above the valve plane, such as in the valve annulus. A tensioning mechanism connecting the ringless web to one or more of the anchors can be used to adjust a tension of the web such that web restrains the leaflet to prevent prolapse by restricting leaflet motion to the coaptation zone and/or promotes natural coaptation of the valve leaflets.
