Abstract: A stented prosthetic heart valve including a stent assembly, a leaflet assembly, and mounting members. The stent assembly includes a stent post frame, a stent post frame covering, and a base frame. The stent post frame includes a continuous rail forming a closed-curved shape defining a longitudinal axis, and a plurality of circumferentially-spaced posts projecting from cusp segments in a direction of the longitudinal axis. The cloth covering encompasses the rail. The base frame supports the cusp segments. The valve leaflet assembly is attached to the stent assembly, and includes a leaflet clamped between one of the cusp segments and the base frame. The mounting members each directly pass through the stent post frame cloth covering, the first leaflet and the base frame. The rail can have a constant cross-sectional shape with a major axis dimension that is greater than a minor axis dimension.

Abstract: Conditioned bioprosthetic tissues for forming prosthetic valves including a sheet of bioprosthetic tissue having a first major surface and a second major surface. The first major surface has a pattern including at least one depressed region and areas of relief adjacent to the at least one depressed region. The at least one depressed region has a first tissue density that is greater than a second tissue density of the areas of relief.

Abstract: Methods of preparing a sheet of bioprosthetic tissue for use as a prosthetic valve leaflet are disclosed. A method includes positioning a sheet of bioprosthetic tissue across an engagement face of a first patterned substrate. The engagement face defines a pattern having at least one raised region and areas of relief adjacent the at least one raised region. The tissue is compressed against the engagement face to deform the tissue to a deformed state corresponding with the pattern.

Abstract: Stented prosthetic heart valves including a stent frame having a plurality of stent frame support structures collectively defining an interior surface, an exterior surface and a plurality of cells. The stented prosthetic heart valve further including a valve structure including valve leaflets disposed within and secured to the stent frame and defining a margin of attachment. The stented prosthetic heart valve including one or both of an outer paravalvular leakage prevention wrap and an inner skirt for supporting the valve leaflets. In various embodiments, the outer wrap is positioned entirely on one side of the margin of attachment. In embodiments including an inner skirt, the outer wrap and the inner skirt are on opposite sides of the margin of attachment such that the inner skirt and the outer wrap do not overlap. In other embodiments, the outer wrap includes a plurality of zones having varying thickness.

Abstract: A method of reinforcing or repairing a bioprosthetic tissue for use as a prosthetic valve leaflet. The method includes evaluating a bioprosthetic tissue, identifying a defect in the bioprosthetic tissue, and selectively applying an adhesive to a surface of the bioprosthetic tissue at the defect prior to implantation in a patient.

Abstract: Prosthetic heart valve devices and associated methods for percutaneous heart valve replacement are disclosed herein. A transcatheter valve prosthesis configured in accordance herewith includes a frame having a valve support and one or more support arms coupled thereto. The one or more support arms are configured to extend from the second end of the valve support toward the first end when the valve prosthesis is in an expanded configuration. When deployed in the expanded configuration, the one or more support arms have a curvilinear shape, such as a substantially S-shape, that at least partially engages tissue at the native heart valve.
