Abstract: A heart valve assembly includes an inner frame comprising a graft covering housing a prosthetic heart valve, wherein the graft covering extends around the prosthetic heart valve for providing sealing to the heart valve, an outer frame formed from a metallic material and defining a gridded configuration, and being secured to the graft covering by a plurality of stitches, and a sealing material positioned externally to the outer frame for providing sealing between the outer frame and a patient's anatomical wall to prevent paravalvular leaks. The sealing material includes a plurality of radially extending fibers that extend outwardly of the outer frame. The graft covering is made of polyester, polytetrafluoroethylene, expanded polytetrafluoroethylene, or a polymer.

Abstract: A multi-spiral, self-expanding stent is constructed from superposed individual spiral strands. Each spiral strand comprises a terminal bend that separates the strand into a first portion and a second portion. Particularly, the first portion of each strand bends in a first spiral direction to the terminal bend, and the second portion bends in the opposite direction after the terminal bend. Advantageously, the disclosed stent is able to change its shape, diameter, and length to accommodate the corresponding shape, diameter, and length of patient's diseased vessel.

Abstract: A transcatheter valve includes an outer seal made of outwardly extending fibers and is configured for transfemoral delivery within a patient.

Abstract: A device and method for repair of a patient's aorta is disclosed. The device includes a first component including an outer diameter equal to a first diameter, a second component attached to a distal end of the first component, and a plurality of third components positioned in a chamber defined in the second component. The second component includes a proximal surface extending outwardly from the distal end of the first component, and a plurality of openings defined in the proximal surface. Each third component includes a passageway extending inwardly from an opening of the plurality of openings defined in the proximal surface. Each passageway is sized to receive a tubular conduit, and the proximal surface has an outer edge that defines a second diameter greater than the first diameter.

Abstract: A transcatheter valve assembly replacement device includes an improved paravalvular seal.

Abstract: A transcatheter valve assembly replacement device includes a paravalvular seal that includes outwardly extending fibers that create a seal with the annulus when the valve assembly is deployed. An inwardly extending seal is attached to an outer frame. The inwardly extending seal is engaged with prosthetic valve leaflets.

Abstract: The abstract has been amended to the following: “A heart valve replacement device for endovascular repair is provided. The heart valve replacement device includes a plurality of fibers for creating a seal with an anatomy of the patient. A heart valve carried by an inner graft covering. The plurality of fibers form an outer seal for preventing paravalvular leaks between the replacement heart valve and the native valve of a patient.

Abstract: An endovascular heart valve assembly includes an inner frame comprising a graft covering housing a prosthetic heart valve, an outer frame formed from a metallic material and defining a gridded configuration. A sealing material includes a plurality of radially extending fibers that extend outwardly of the outer frame. The plurality of radially extending fibers include first fibers extending from a first position relative to the outer frame and second fibers extending from a second position relative to the outer frame that is distally spaced-apart from the first position. The gridded configuration includes an uncovered open cell between the first position and the second position. The first fibers and the second fibers are configured to cooperatively form a seal when compressed within the aortic annulus. A length of the first fibers is greater than a height of the uncovered open cell.

Abstract: An endovascularly deployed prosthetic includes a portion for being positioned within an ascending aorta. The prosthesis includes a replacement aortic valve on a proximal end thereof. The prosthesis includes an increased diameter portion that seals against the aorta at a more distal portion, and a pair of conduits extend from the increased diameter portion to the coronaries for fluidly coupling the coronaries to the prosthesis.
