Abstract: A unitary flexible sheet (612) is folded to define (i) a panel (608); (ii) a first tab (606a), having a first-tab outer layer and a first-tab inner layer, and protruding away from the panel; and (iii) a second tab (606b), having a second-tab outer layer and a second-tab inner layer, and protruding away from the panel. A commissural portion of a first prosthetic leaflet (58a), and a commissural portion of a second prosthetic leaflet (58b) are disposed between the first-tab inner layer and the second-tab inner layer. A first stitching (632) is stitched through the inner layer of each tab, and the commissural portion of each leaflet. A second stitching (634) is stitched through the outer and inner layers of each tab, and the commissural portion of each leaflet. The first-tab outer layer and the second-tab outer layer cover the first stitching. Other embodiments are also described.

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.

Abstract: A valve body circumscribes a longitudinal axis and defines a lumen along the axis. Upstream arms are coupled to the valve body, and extend radially outward from the valve body to respective arm-tips. Downstream legs are coupled to the valve body, and extend radially outward from the valve body and toward the plurality of arms. A flexible pouch extends radially outward from the valve body. The arms and the legs narrow the pouch therebetween to form a narrowed portion of the pouch, thereby defining, in an interior space of the pouch: (a) an inner portion, radially inward from the narrowed portion, and in fluid communication with the lumen, and (b) an outer portion, radially outward from the narrowed portion, and in fluid communication with the inner portion via the narrowed portion. Other embodiments are also described.

Abstract: An implant includes a support frame, having a compressed state, and an expanded state in which the support frame defines an opening therethrough, and is dimensioned to be placed against an upstream surface of a native heart valve. The implant includes a valve frame having a compressed state, and an expanded state in which the valve frame defines a lumen therethrough, and including a valve member disposed within the lumen. The valve frame is coupled to the support frame via a flexible sheet such that when the support and valve frames are in their expanded state, the valve frame is not in contact with the support frame. The implant is housed in the catheter for implanting transfemorally, with the valve frame closer to a distal end of the catheter than the support frame is to the distal end of the catheter. Other embodiments are also described.

Abstract: A unitary flexible sheet is folded to defines a panel, and first and second tabs. Each of the tabs has an inner layer and an outer layer. Commissural portions of prosthetic leaflets are sandwiched between inner layers of the first and second tabs. The tabs protrude from a first side of the panel, and are shaped such that progressively downstream parts of each tab protrude progressively further away from the panel portion. Other embodiments are also described.

Abstract: A prosthetic valve includes a tubular valve body, snares, and an upstream support. A native valve of a heart of a subject is disposed between an atrium and a ventricle of the heart, and has an annulus and leaflets. The prosthetic valve is advanced to the heart while in a compressed state. The prosthetic valve is positioned within the heart such that the snares are disposed upstream of the annulus and leaflets. The snares are expanded radially outwardly upstream of the leaflets. Subsequently, the prosthetic valve is moved in a downstream direction such that the snares become disposed downstream of the leaflets. While the snares remain downstream of the leaflets, the upstream support is expanded within the atrium, and the upstream support is placed against an upstream surface of the annulus. Other embodiments are also described.

Abstract: Prosthetic valves and methods of implanting prosthetic valves may be provided, including an expandable prosthetic valve for implantation within a native heart valve. The prosthetic valve may include an annular valve body and atrial anchoring arms configured to extend radially outward from the annular valve body. Each atrial anchoring arm may have a proximal arm end and a distal arm end. The flexibility of at least one atrial anchoring arm may vary substantially from the proximal arm end thereof to the distal arm end thereof. The prosthetic valve may also include a plurality of ventricular anchoring legs configured to extend radially outward from the annular valve body. Each ventricular anchoring leg may have a proximal leg end and a distal leg end. Each ventricular anchoring leg may have a substantially constant flexibility from the proximal leg end to the distal leg end.

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: 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.
