    Abstract: An expandable prosthetic valve for implantation within a native mitral valve may be provided. The prosthetic valve may include an expandable valve body having an atrial end, a ventricular end opposite the atrial end, and an intermediate portion extending between the atrial end and the ventricular end. The valve body may include a plurality of struts intersecting at junctions. The prosthetic valve may also include a plurality of tissue anchoring legs extending from junctions within the intermediate portion of the valve body. At least one of the tissue anchoring legs may have a cross-sectional area which is larger by at least 20% than a cross-sectional area of a strut extending between the at least one tissue anchoring leg and an adjacent tissue anchoring leg.

    Abstract: A prosthetic valve is provided that includes a tubular valve body and a plurality of prosthetic leaflets disposed within a lumen of the valve body. The valve body includes struts, has an upstream end and a downstream end, and defines a lumen. The valve body is shaped so as to define a circumferential row of four-sided closed cells. Each of the four-sided closed cells is defined by some of the struts, which are shaped so as to collectively define the following four sides: a left upstream side, a right upstream side, a left downstream side, and a right downstream side. Exactly two of the four sides of each of the four-sided closed cells are double-strutted. Other embodiments are also described.

    Abstract: A prosthetic valve includes a tubular portion coupled to an upstream support portion, and ventricular legs. The prosthetic valve is transitionable from a compressed state into a partially-expanded state in which (1) a downstream surface of the support portion defines (i) an annular concave region extending radially between a concave-region inner radius and a concave-region outer radius, and (ii) an annular convex region, radially outward from the annular concave region, extending radially between a convex-region inner radius and a convex-region outer radius, and (2) the tip of each leg is disposed radially between the concave-region inner radius and the concave-region outer radius. In a fully-expanded state each leg's tip is disposed radially between the convex-region inner radius and the convex-region outer radius. Other embodiments are also described.

    Abstract: Embodiments of the present disclosure include a method for use at a native valve of a heart of a subject. At a distal portion of a delivery tool, a balloon is coupled to a shaft. The distal portion is advanced to the heart with an implant and the balloon disposed within a capsule. The implant includes a tubular frame and one or more shape-memory flanges. The tubular frame is compressed around the balloon, and the flanges are constrained within a downstream capsule-portion of the capsule. The flanges are exposed from the downstream capsule-portion such that the flanges automatically deflect radially outward. Subsequently, the flanges are pressed against a downstream surface of the native valve by moving the implant in an upstream direction. While the flanges are in contact with the downstream surface, the tubular frame is plastically expanded radially by inflating the balloon. Other embodiments are also described.

    Abstract: Embodiments of the present disclosure include apparatus including a percutaneous delivery capsule and prosthetic valve. The prosthetic valve includes a frame assembly that includes a tubular portion, and a plurality of atrial arms that extend away from the tubular portion. A plurality of prosthetic leaflets are attached to the tubular portion, and are disposed within a lumen defined by the tubular portion. When the prosthetic valve is in a compressed state and is housed by the capsule, each of the atrial arms extends, in a serpentine shape, along the capsule and away from the tubular portion. Other embodiments are also described.

    Abstract: A prosthetic valve for implantation within a native heart valve may be provided. The prosthetic valve may include an annular valve body, as well as a plurality of ventricular anchoring legs and a plurality of atrial anchoring arms configured to extend radially outward from the annular valve body. The ventricular anchoring legs and grasping segments of the atrial anchoring arms may be configured to substantially restrict axial movement of the annular valve body within the native heart valve. In addition, anchoring segments of the atrial anchoring arms may be configured for lateral deformation relative to the native heart valve.

    Abstract: A prosthetic valve delivery system may be provided. The prosthetic valve delivery system may include a first catheter and a first steering mechanism configured to bend the first catheter within a first steering plane. The prosthetic valve delivery system may also include a second catheter coaxially arranged within the first catheter and a second steering mechanism configured to bend the second catheter within a second steering plane, different from the first steering plane. Moreover, the prosthetic valve delivery system may include a capsule positioned distal to both the first catheter and the second catheter. The capsule may be configured to retain a prosthetic valve therein during transvascular advancement of the capsule.
