    摘要: A prosthetic heart valve has an annular valve-perimeter-shape-defining structure having a radially outer surface. A clip structure is provided on the outer surface. This clip structure is used to attach flexible valve leaflets to the shape-defining structure. One or more retainer members may be used to help hold the leaflets in the clip structure.

    摘要: A prosthetic heart valve of the type that includes a hollow annular stent and a plurality of flexible leaflets that are attached to the stent. One or more fixture structures are used to attach the leaflets to the stent so that sutures do not have to be used for that purpose. The fixture structures preferably extend annularly at least substantially all the way around the valve. Surfaces of the fixture structures that can come into contact with portions of the leaflets that move during use of the valve can be shaped to help beneficially shape those leaflet portions during their movements.

    摘要: A prosthetic heart valve includes an annular stent structure having a plurality of annularly spaced stent post regions, a plurality of leaflets that extend radially inward from the stent structure and that include radially outer portions that lie against a radially outer surface of the stent structure, and a clamping structure that is radially outside the other components and that clamps the radially outer portions of the leaflets against the radially outer surface of the stent structures to secure the leaflets to the stent structure. The above-described structural arrangement applies to the stent post regions as well as to other portions of the stent structure.

    摘要: A prosthetic heart valve includes a stent having a collapsed condition and an expanded condition. The stent includes a plurality of cells, each cell being formed by a plurality of struts, and a plurality of commissure features. The heart valve further includes a valve assembly secured to the stent and including a cuff and a plurality of leaflets, each leaflet being attached to adjacent commissure features and to the stent struts and/or the cuff.

    摘要: A mandrel (5) for molding polymer valve leaflets for heart valve prostheses is disclosed, including a body portion (52) including an outer surface with ridges (60) and contoured surfaces (64) corresponding to the leaflets, the upper edge of the contoured surfaces corresponding to the free upper edge of the leaflets, and the mandrel including a mandrel extension (54) above the body portion, and a gap (68) extending around the mandrel between the upper edge of the contoured surface and the mandrel extension. A process for producing these polymer valve leaflets is also disclosed by dip coating with this mandrel and re-moving the polymer film created at the gap, preferably by applying suction or blowing thereto.
