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 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.

摘要： A heart valve annulus sizer is provided for measuring a valve to be fitted with an annuloplasty ring. The sizer may include a body having a peripheral portion defining an opening, at least one rib disposed within the opening and dividing the opening into at least a first opening and a second opening, and an anchor disposed on and projecting from the body. The sizer may include a length of suture connected to the body. The anchor may include an aperture adapted to receive the length of suture. A method of using the sizer is provided that includes grasping the sizer with an instrument and positioning the sizer adjacent to a valve into a position suitable to allow for measurement of the valve.

摘要： A structure for use as a prosthetic heart valve leaflet includes a two-dimensional array that is made up of one or more fiber strands and that is covered by a web of polymer material to produce a sheet that is impervious to blood. This sheet is stretchable along two axes that lie in the plane of the sheet and that are at an angle to one another. The sheet may be more easily stretched along one of these axes than along the other axis. Along each axis the amount of force required to produce initial increments of stretch may be less than the amount of force required to produce subsequent increments of stretch (i.e., increments of stretch beyond the initial increments).
