Abstract
Apparatuses, systems, and methods for prosthetic valves. Examples of prosthetic valves may be configured to anchor to an interior surface of a heart valve. Such prosthetic valves, in examples, may include a single frame that supports a plurality of prosthetic valve leaflets. In examples, multiple frames may be utilized to anchor to a heart valve and one or more of the frames may support a plurality of prosthetic valve leaflets.
Claims20
A system comprising:
- a prosthetic valve including:
- a plurality of prosthetic valve leaflets;
- an inner frame for supporting the plurality of prosthetic valve leaflets, the inner frame having a proximal end and a distal end;
- and
- an anchoring body positioned radially outwardly of the inner frame for anchoring to a native heart valve, the anchoring body including a proximal frame portion and a distal frame portion, wherein an annular recess is provided between the proximal frame portion and the distal frame portion for receiving an annulus of a native heart valve;
- wherein a proximal end of the proximal frame portion is positioned proximal to the proximal end of the inner frame, and
- wherein a distal end of the distal frame portion is positioned distal to the distal end of the inner frame.
A prosthetic valve for implantation within a native heart valve, the prosthetic valve comprising:
- a plurality of prosthetic valve leaflets;
- an inner valve body supporting the plurality of prosthetic valve leaflets and configured to be expanded with an inflatable body;
- and
- a self-expanding outer valve body configured to extend radially outward from the inner valve body.
A prosthetic valve, comprising:
- a plurality of prosthetic valve leaflets;
- an inner frame for supporting the plurality of prosthetic valve leaflets;
- and
- an anchoring body positioned radially outward of the inner frame and shaped for anchoring to a native heart valve, the anchoring body including:
- a proximal frame portion and a distal frame portion, wherein an annular recess is provided between the proximal frame portion and the distal frame portion for receiving tissue of a native heart valve, the proximal frame portion forming a first shoulder positioned proximal of the annular recess, and the distal frame portion forming a second shoulder positioned distal of the annular recess, and wherein the proximal frame portion includes a proximal end spaced from the inner frame, and the distal frame portion includes a distal end spaced from the inner frame.
