Abstract: In one embodiment, a method of assembling a prosthetic valve can comprise forming a radially expandable and compressible frame by pivotally joining together a plurality of struts without requiring individual rivets. In some embodiments, the frame is formed by interweaving the struts, which can be joined using integral hinges formed in the struts, such as by performing alternate cuts on the struts, bending the struts to form stopper tabs adjacent to joints and/or drilling holes in the struts to facilitate interconnecting struts at joints, or otherwise forming integral hinges and corresponding holes at junction points between the struts. In other embodiments, separate hinges are provided to interconnect the struts. In still other embodiments, separate flanged rivets are provided to connect the struts.

Abstract: A prosthetic heart valve and associated methods for assembling a prosthetic heart valve including a plurality of leaflets is disclosed. As one example, a prosthetic heart valve includes a frame; a plurality of commissure support elements, each connected the frame and including two axially-extending members spaced apart from one another to form a window; and a plurality of leaflets, each leaflet comprising a body and two opposing commissure tabs, each commissure tab arranged adjacent to another commissure tab to form a pair of commissure tabs that are disposed in a commissure support element to form a commissure. Each commissure tab includes a series of overlapping layers that include a first set of two overlapping layers that extends through the window and a second set of two overlapping layers that extends away from the first set of two overlapping layers and over an outer side of a corresponding axially-extending member.

Abstract: A prosthetic heart valve comprises an annular frame that is radially compressible and expandable between a radially compressed state and a radially expanded state, wherein the frame elongates in an axial direction when radially compressed from the radially expanded state to the radially compressed state. Leaflets are coupled to the frame such that when the frame is in the radially expanded state, the leaflets have slack in an axial direction, wherein when the frame is radially compressed to a partially radially compressed state between the radially expanded state and the radially compressed state, the leaflets are in a relaxed state, and wherein when the frame is in the radially compressed state, the leaflets are stretched in the axial direction.

Abstract: An implantable prosthetic valve can include a frame movable between a radially compressed and a radially expanded configuration. The frame can include a first strut having a first locking feature disposed on a radially facing inner surface of the strut and a second strut having a second locking feature disposed on a radially facing outer surface of the strut. The first and second locking features can engage each other so as to allow pivoting of the first and second struts relative to one another in a first direction upon radial expansion of the frame and resist pivoting of the first and second struts relative to one another in a second direction to resist radial compression of the frame.

Abstract: A method of implanting a prosthetic heart valve within a patient can comprise inserting a distal end portion of a delivery apparatus and a prosthetic heart valve into the patient and advancing the prosthetic heart valve to a deployment location within the heart of the patient and inflating one or more of a plurality of differently-sized balloons in a balloon-assembly on the distal end portion of the delivery apparatus. The prosthetic heart valve can be mounted on the balloon assembly in a crimped state and the inflating of the one or more of the plurality of differently-sized balloons can expand the prosthetic heart valve from the crimped state to a radially expanded state having a non-cylindrical shape.

Abstract: Disclosed are techniques for construction of prosthetic heart valves, particularly techniques for attachment of scalloped edges of valvular leaflets to struts of mechanical frames using sutures and/or other materials as intermediate coupling members. In some embodiments, the scalloped edges of the leaflets are coupled to the segments of the struts of the frame via suture loops that are oriented transverse to the scalloped edges of the leaflets. In some embodiments, central portions of scallop line segments are attached to the scalloped edges of the leaflets and are not attached to the frame. In some embodiments, strut segments are tapered to limit translation of suture loops. In some embodiments, a cloth strip couples the scalloped edges of the leaflets to frame struts. In some embodiments, the scalloped edge is attached to adjacent segments of intersecting struts via sliding suture loops, where the adjacent segments join at a common pivot joint.

Abstract: A prosthetic heart valve includes a frame, a valvular structure coupled to the frame, and a sealing member coupled to the frame. The frame has inflow and outflow ends and a lumen extending therebetween. The frame includes struts that form cells, and the cells are arranged in three rows. The frame is radially expandable from a collapsed state to an expanded state. The valvular structure includes a plurality of leaflets configured to allow blood flow through the lumen of the frame from the inflow end to the outflow end and to block blood flow through the lumen of the frame from the outflow end to the inflow end. The sealing skirt extends from an intermediate location of the frame disposed between the inflow and outflow ends to the inflow end of the frame. The sealing skirt covers two rows of cells to block blood flow through the cells.

Abstract: A prosthetic heart valve includes a collapsible and expandable annular frame. The frame includes a plurality of rows of hexagonal cells. Each of the hexagonal cells is defined by six struts, including: two opposing side struts extending parallel to each other, a first pair of angled struts extending from respective first ends of the side struts and converging to intersect with each other, and a second pair of angled struts extending from respective second ends of the side struts and converging to intersect with each other. The prosthetic heart valve can also include a valvular structure with a plurality of leaflets. The prosthetic heart valve can further include a sealing member.
