    • 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.
    • 一种假体心脏瓣膜,其类型包括中空环形支架和附接到支架的多个柔性小叶。 使用一个或多个夹具结构将传单附接到支架上,使得缝合线不必用于该目的。 固定结构优选地至少基本上围绕阀全部地环向延伸。 能够与使用阀门期间移动的小叶的部分接触的夹具结构的表面可以被成形为有助于在移动过程中有利地塑造这些叶片部分。

    • 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.
    • 公开了一种用于模制用于心脏瓣膜假体的聚合物瓣膜小叶的心轴(5),包括主体部分(52),其包括具有脊(60)的外表面和对应于小叶的轮廓表面(64),轮廓的 表面对应于小叶的自由上边缘,并且心轴包括在主体部分上方的心轴延伸部(54),以及在成形表面的上边缘和心轴延伸部之间围绕心轴延伸的间隙(68)。 通过用该心轴进行浸渍涂覆也可以公开制造这些聚合物瓣叶的方法,并且重新移动在间隙处产生的聚合物膜,优选通过施加吸力或吹送。

    • 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.
    • 提供心脏瓣膜环形分选器用于测量与瓣环成形术环配合的瓣膜。 分级机可以包括具有限定开口的周边部分的主体,设置在开口内的至少一个肋条,并将开口分成至少第一开口和第二开口,以及锚定件,其设置在主体上并从主体突出。 定径机可以包括连接到身体的一段缝线。 锚定器可以包括适于接收缝合长度的孔。 提供了一种使用分级器的方法,其包括用仪器抓住分级器并将分级器邻近阀定位到适于允许测量阀的位置。
