    摘要： A heart valve annulus sizer (10) is provided for measuring a valve to be fitted with an annuloplasty ring. The sizer (10) may include a body (17) having a peripheral portion (18) defining an opening (18a), at least one rib (15) disposed within the opening (18a) and dividing the opening (18a) into at least a first opening (16) and a second opening (16), and an anchor (11) disposed on and projecting from the body (17). The sizer (10) may include a length of suture (75) connected to the body (17). The anchor (11) may include an aperture (11a) adapted to receive the length of suture (75). A method of using the sizer (10) is provided that includes grasping the sizer (10) with an instrument and positioning the sizer (10) adjacent to a valve into a position suitable to allow for measurement of the valve.

    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 removing the polymer film created at the gap, preferably by applying suction or blowing thereto.
