  • Publication number: 20220234306
    Abstract: A prosthetic heart valve has a radially expandable and collapsible annular frame, the frame having an inflow end and an outflow end and defining a longitudinal axis along a lumen of the prosthetic heart valve when it is in the expanded configuration. A leaflet structure is positioned within the frame and secured thereto. The prosthetic heart valve also has a laminate sealing member including a plurality of layers heat-bonded together to encapsulate at least a portion of the frame. The laminate sealing member extends along the longitudinal axis in an upstream direction and doubles back toward the outflow end of the frame at a fold line to form a cuff, and an edge portion of the laminate sealing member is secured to a main portion of the laminate sealing member downstream of the fold line such that the cuff forms an inflow end of the laminate sealing member.

  • Publication number: 20220211495
    Abstract: An implantable prosthetic valve includes a radially collapsible and expandable annular frame having three commissure attachment posts and four rows of circumferential struts. The rows include a first row, a second row downstream of the first row, a third row downstream of the second row, and a fourth row downstream of the third row and defining an outflow end of the frame. Each row of circumferential struts includes angled struts arranged in a zig-zag pattern. A leaflet structure includes three leaflets forming three commissures, each commissure being connected to one of the commissure attachment posts only at locations along the commissure attachment posts between a first plane that is perpendicular to a longitudinal axis of the frame and intersects crowns of the third row of struts and a second plane that is perpendicular to the longitudinal axis and intersects crowns of the fourth row of struts.

  • Patent number: 11278400
    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.

  • Patent number: 11213388
    Abstract: A method of crimping an implantable prosthetic valve can include placing protective material over at least a portion of the implantable prosthetic valve. The protective material can be configured to occupy space between open cells of a frame of the implantable prosthetic valve to prevent damage to a leaflet structure of the implantable prosthetic valve. The method can also include crimping the implantable prosthetic valve with the protective material on the implantable prosthetic valve, and removing the protective material from between the frame and the leaflet structure of the implantable prosthetic valve.

  • Publication number: 20200405482
    Abstract: A prosthetic heart valve comprises a radially collapsible and expandable annular frame and a leaflet structure comprising three leaflets. Each leaflet has an upper edge portion, a curved lower edge portion and two side flaps, wherein each side flap is connected to an adjacent side flap of another leaflet to form commissures of the leaflet structure, with each commissure being attached to the frame. An annular inner sleeve comprises three U-shaped portions positioned along the curved lower edge portions of the leaflets. An annular outer sleeve extends around are outer surface of the frame, wherein the outer sleeve is made of pericardium. The frame is made of Nitinol and the prosthetic valve can be radially crimped to a radially collapsed configuration inside a sheath for delivery into a patient's body and self-expand to a radially expanded configuration when released from the sheath inside the patient's body.

  • Patent number: 10799344
    Abstract: A prosthetic heart valve includes a frame, a valve member, and a sealing member. The frame is expandable from a collapsed state to an expanded state. The frame has inflow and outflow ends, a lumen extending between the ends, and a plurality of struts defining a plurality of cells. The valve member is disposed within the lumen of the frame and is movable between open and closed configurations. The sealing member is mounted inside of the frame. When the frame is in the expanded state and the valve member is in the closed configuration, portions of the sealing member can protrude outwardly through the cells of the frame and extend beyond an exterior surface of the struts of the frame.
