A frame for a prosthetic valve includes pivoting struts and outer bow struts. A first end of each pivoting strut is pivotably coupled to a first pivoting strut, a second end of each pivoting strut is pivotably coupled to a second pivoting strut, and an intermediate portion of each pivoting strut, which is disposed between the first end and the second end, is pivotably coupled to a third pivoting strut. The outer bow struts are disposed outwardly from the pivoting struts. An inflow end of each outer bow strut is connected to the first end of a respective pivoting strut, and an outflow end of each outer bow strut is connected to the second end of a respective pivoting strut. The outer bow struts deflect outwardly relative to the intermediate portions of the pivoting struts when the frame is moved from a radially compressed configuration to a radially expanded configuration.

Articulated commissure valve stents and methods

A prosthetic heart includes a support structure, an actuator member, a plurality of leaflets, and a sealing material. The support structure includes a plurality of struts movably coupled together such that the support structure moves incrementally between a radially compressed state and a radially expanded state. The struts include a plurality of commissure struts. The actuator member is coupled to the struts of the support structure and is configured to incrementally move the support structure between the radially compressed state and the radially expanded state and to automatically lock the support structure in a particular state. The leaflets are coupled to the commissure struts of the support structure and configured to allow unidirectional blood flow through the prosthetic heart valve. The sealing material is coupled to the support structure and includes a plurality of commissure extensions that wrap around and are coupled to the commissure struts of the support structure.

Systems and methods for manufacturing a stent frame

A prosthetic heart valve includes a frame, a valve component, and an actuation mechanism. The frame has a plurality of struts interconnected by a plurality of joints and is movable between expanded and compressed configurations. The valve component is inside the frame and has a plurality of leaflets. The actuation mechanism has a first expansion element coupled to the frame at a first location and a second expansion element coupled to the frame at a second location. The actuation mechanism is configured such that moving the first expansion element and the second expansion element toward each other in a first direction results in the frame moving from the compressed configuration to the expanded configuration, and such that moving the first expansion element and the second expansion element away from each other in a second direction results in the frame moving from the expanded configuration to the compressed configuration.

Repositionable endoluminal support structure and its applications

A prosthetic heart valve can include a support structure, an actuator member, and a plurality of leaflets. The support structure can have a plurality of struts and a plurality of rivets. The struts can have openings formed therein. The rivets can have first portions and second portions. The first portions can extend through the openings of the struts, and the second portions are larger than the first portion and the openings of the struts. The struts are pivotable about the rivets to radially expand and compress the support structure. The actuator member can be coupled to the struts of the support structure and configured to selectively actuate expansion and compression of the support structure. The leaflets can be coupled to the support structure and configured to allow unidirectional blood flow through the prosthetic heart valve.

A prosthetic heart valve can include an inner support structure, a valve member, and an outer support structure. The inner support structure can have a plurality of first struts coupled together by first pivot joints and forming a first lumen. The valve member can be disposed within the first lumen and coupled to the inner support structure. The valve member can include a plurality of leaflets configured for permitting blood flow through the valve member in one direction. The outer support structure can have a plurality of second struts coupled together by second pivot joints and can form an annulus portion, an outflow portion, and a second lumen. The outflow portion can extend radially outwardly relative to the annulus portion, and the inner support structure and the valve member can be disposed within the second lumen and be coupled to the outer support structure.

A prosthetic heart valve includes a frame, a valve component, and a skirt. The frame has first and second end portions, a central longitudinal axis extending between the first and second end portions, and a plurality of struts interconnected by a plurality of joints. The joints comprise a rotational axis perpendicular to the longitudinal axis. The frame is movable between an expanded configuration and a compressed configuration. The struts comprise diagonal struts relative to the longitudinal axis when the frame is in the expanded configuration. The valve component has a plurality of leaflets. Adjacent leaflets are attached together and to the frame at commissures of the frame. The leaflets extend from the commissures in a triangular configuration and are attached to adjacent diagonal struts of the frame. The skirt is configured for reducing paravalvular leakage and attached to the diagonal struts of the frame to which the leaflets are attached.

An endoluminal support structure includes strut members interconnected by swivel joints to form a series of linked scissor mechanisms. The structure can be remotely actuated to compress or expand its shape by adjusting the scissor joints within a range of motion. In particular, the support structure can be repositioned within the body lumen or retrieved from the lumen. The support structure can be employed to introduce and support a prosthetic valve within a body lumen.
