  • Patent number: 11678980
    Abstract: An apical pad for securing a prosthetic heart valve within a native valve annulus. The apical pad includes a first collar, a second collar and plurality of struts extending between the first collar and the second collar. The plurality of struts has a delivery condition in which the plurality of struts collectively form a first cross-section and a deployed condition in which the plurality of struts collectively form a second cross-section greater than the first cross-section. The apical pad may be coupled to a tether extending from a prosthetic heart valve and may transition from the delivery condition to the deployed condition by tensioning the tether.

  • Patent number: 11678972
    Abstract: An adjustable implant is disclosed herein. The adjustable implant may comprise a shell including membrane and a base and having a first diameter in a plane parallel to the base. A band may be disposed within the shell. The band may have a first end and a second end connected to a spool. The band may be in a round (e.g., elliptical) configuration having a second diameter in the plane that is less than the first diameter. By wrapping the band onto the spool, the diameter of the band may be decreased and the height of the implant may be increased. By unwrapping the band from the spool, the diameter of the band may be increased and the height of the implant may be decreased.

  • Patent number: 11660187
    Abstract: A prosthetic heart valve is designed to be circumferentially collapsible for less invasive delivery into the patient. At the implant site the valve re-expands to a larger circumferential size, i.e., the size that it has for operation as a replacement for one of the patient's native heart valves. The valve includes structures that, at the implant site, extend radially outwardly to engage tissue structures above and below the native heart valve annulus. These radially outwardly extending structures clamp the native tissue between them and thereby help to anchor the prosthetic valve at the desired location in the patient.
