Abstract
Prosthetic valves and methods of use of prosthetic valves may be provided. In one implementation, a prosthetic valve may include an annular outer frame, an inner frame, and a plurality of ventricular anchoring legs extending from the outer frame. The outer frame may be formed at least partially of struts intersecting at junctions. At least one ventricular anchoring leg may include a first curved leg portion on a first surface of the leg, and a second curved leg portion on a second, opposite surface of the leg. The outer frame may also include a strut extending between a downstream end of the outer frame and the junction from which the at least one ventricular anchoring leg extends.
Claims20
An expandable prosthetic valve configured for implantation within a native heart valve, the prosthetic valve comprising:
- an annular outer frame formed at least partially of outer frame struts intersecting at outer frame junctions;
- an inner frame situated at least partially within the annular outer frame and formed at least partially of inner frame struts intersecting at inner frame junctions;
- and
- a plurality of ventricular anchoring legs extending from the annular outer frame, each ventricular anchoring leg comprising:
- a proximal leg end secured to an outer frame junction of the annular outer frame, and
- a terminal leg end opposite from the proximal leg end, wherein
- at least one ventricular anchoring leg includes:
- a first surface extending between the proximal leg end and terminal leg end of the at least one ventricular anchoring leg, the first surface having a first curved leg portion configured to have a convex arrangement with respect to a longitudinal axis of the prosthetic valve, and
- a second surface extending between the proximal leg end and terminal leg end of the at least one ventricular anchoring leg, the second surface being situated on an opposite side of the ventricular anchoring leg from the first surface and having a second curved leg portion situated between the first curved leg portion and the terminal leg end, wherein the second curved leg portion is configured to have a concave arrangement with respect to the longitudinal axis of the prosthetic valve,
- the annular outer frame includes a first outer frame strut extending between a downstream end of the annular outer frame and the outer frame junction from which the at least one ventricular anchoring leg extends, and
- the first outer frame strut and at least one of the first curved leg portion and the second curved leg portion of the at least one ventricular anchoring leg are situated at the same circumferential position about the prosthetic valve as the terminal leg end of the at least one ventricular anchoring leg.
An expandable prosthetic valve configured for implantation within a native heart valve, the prosthetic valve comprising:
- a valve body including an annular outer frame and an inner frame situated at least partially within the annular outer frame;
- a plurality of atrial anchoring arms configured to extend radially outward from the valve body, each atrial anchoring arm comprising:
- a proximal arm end secured to one of the annular outer frame or the inner frame, and
- a terminal arm end opposite from the proximal arm end;
- and
- a plurality of ventricular anchoring legs configured to extend radially outward from the valve body, each ventricular anchoring leg comprising:
- a proximal leg end secured to the other of the annular outer frame or the inner frame, and
- a terminal leg end opposite from the proximal leg end, wherein
- at least one ventricular anchoring leg includes:
- a first surface extending between the proximal leg end and terminal leg end of the at least one ventricular anchoring leg, the first surface having a first curved leg portion situated between the proximal leg end and the terminal leg end, wherein the first curved leg portion is configured to have a convex arrangement with respect to a longitudinal axis of the prosthetic valve, and
- a second surface extending between the proximal leg end and terminal leg end of the at least one ventricular anchoring leg, the second surface being situated on an opposite side of the ventricular anchoring leg from the first surface and having a second curved leg portion situated between the first curved leg portion and the terminal leg end, wherein the second curved leg portion is configured to have a concave arrangement with respect to the longitudinal axis of the prosthetic valve, and
- the prosthetic valve is configured to be symmetrical, with respect to the longitudinal axis of the prosthetic valve.
