Abstract: A belt for an implantable prosthetic device can include an annular body including a plurality of alternating peaks and valleys and a plurality of frangible members extending between at least one of adjacent peaks and adjacent valleys. The annular body can be radially expandable from a radially compressed configuration to a first diameter upon application of a radially outwardly directed force via an expandable implantable prosthetic device. A first frangible member of the plurality of frangible members can be configured to break when the radially outwardly directed force exceeds a first predetermined threshold to allow radial expansion of the annular body to a second diameter.

Abstract: A prosthetic heart valve includes an expandable annular frame and a valvular structure. The annular frame has an inflow end and an outflow end separated from the inflow end along an axial direction of the frame. The annular frame can also comprise a plurality of commissure support posts. The valvular structure is supported within the annular frame and includes a plurality of leaflets. Each leaflet has a pair of tabs. The tabs of adjacent leaflets are paired together to form a commissure tab assembly. Each commissure tab assembly is coupled to a corresponding one of the commissure support posts. Each commissure support post has a first portion with one or more protrusions arranged along an axial direction of the frame so as to restrain axial motion of the respective commissure tab assembly.

Abstract: An implantable prosthetic valve that is radially collapsible to a collapsed configuration and radially expandable to an expanded configuration comprises an annular frame having an inflow end and an outflow end, a leaflet structure positioned within the frame and secured thereto, and a laminate sealing member comprising an encapsulating material. The laminate sealing member has a main portion that encapsulates at least a portion of the frame and an end portion extending from the inflow end of the frame, and the end portion of the laminate sealing member is folded to form a cuff adjacent the inflow end of the frame and secured to the main portion of the laminate sealing member.

Abstract: An implantable prosthetic valve assembly, according to one embodiment, comprises a frame assembly including a plurality of struts and a prosthetic valve secured inside the frame assembly by sutures. The sutures are inward of the outermost surface of an outer periphery of the frame assembly. In certain embodiments the struts contain recesses in which sutures can be disposed. In other embodiments, the struts can have holes through them which the sutures pass through. The implantable prosthetic valve assembly can also be collapsed within a catheter such that an outermost surface of a periphery of the frame assembly touches the catheter but the sutures are spaced apart from the catheter or are flush with the outer surface of the frame.

Abstract: A prosthetic heart valve includes an annular frame including a plurality of angled strut members that is radially collapsible to a collapsed configuration and radially expandable to an expanded configuration. The frame has an inflow end and an outflow end, and includes a leaflet structure positioned within the frame, the leaflet structure comprising a plurality of leaflets arranged to form a plurality of commissures. The frame includes a plurality of commissure support elements, each commissure support element being positioned at one of the commissures. Each of the commissure support elements has a coupling portion coupled to the frame and first and second members coupled to the coupling portion and extending in a direction toward the inflow end of the frame or toward the outflow end of the frame. The leaflets of each commissure are received between the first and second members of the respective commissure support element.

Abstract: A method for improving leaflet prolapse and/or valve regurgitation associated with a heart valve involves delivering a spacer device into a ventricle of a heart using a delivery system comprising a catheter, fixing the spacer device to a wall of the ventricle, expanding the spacer device to reposition a papillary muscle disposed in the ventricle away from the wall, the papillary muscle being connected to a leaflet of an atrioventricular heart valve via chordae tendineae, and releasing the spacer device from the catheter.

Abstract: Devices, systems and methods are described herein to provide improved steerability for delivering a prosthesis to a body location, for example, for delivering a replacement mitral valve to a native mitral valve location. The delivery system can include a number of advantageous steering and delivery features, in particular for the transseptal delivery approach.

Abstract: Disclosed herein are embodiments of delivery capsules for delivering prosthetic implants around the relatively tight bends of a catheter. In particular, disclosed herein are delivery capsules including a tubular layer for holding the heart valve, a frame enclosing the tubular layer and an elongate element coupled to the frame for allowing the tubular layer and frame to expand. For example, the frame may be biased to expand and withdrawal of the elongate element from openings in the frame can release the frame to expand into a larger diameter. Another embodiment includes a helical wire wrapped around the capsule for easy delivery through bends and a second helical wire that is advanced between windings of the first helical wire to selectively stiffen the capsule for withdrawal. Other embodiments include sock-like capsules that can be crumpled into shorter lengths by pulling a pull line attached to the capsule.

Abstract: Embodiments of a prosthetic heart valve are disclosed. An implantable prosthetic valve may be radially collapsible to a collapsed configuration and radially expandable to an expanded configuration. The prosthetic valve may comprise an annular frame, a leaflet structure positioned within the frame and a plurality of outer skirts positioned around an outer surface of the frame, each outer skirt comprising an inflow edge secured to the frame and an outflow edge secured at intervals to the frame. The plurality of outer skirts may include a first outer skirt and a second outer skirt, wherein in the expanded configuration the first and second outer skirts include openings unsecured to the frame between the intervals. The inflow edge of the first annular outer skirt may be secured to the frame with sutures including radiopaque material. The first annular outer skirt may include radiopaque dye.
