    • A mechanical heart valve having one or more leaflets pivotally fitted in a substantially cylindrical shaped valve body formed from a resiliently deformable material. A stiffening member formed from substantially nonresilient material fit about the valve body exterior wall to provide structural integrity to the valve body. Stresses which are normally applied to the heart valve body during the opening and closing of the valve are absorbed or cushioned by the incorporation of a rubber-like body between the stiffening member and the retainer member. Further cushioning is provided by incorporating another rubber-like body in the sewing ring. This second body extends out from the exterior surface of the valve body. Finally, a length of fabric is positioned about the retainer and shock absorbing bodies. This design provides a precisely calibrated rotational torque which allows for optimum orientation of the leaflets by the implanting surgeon.

    • An improved holder, system and method for implanting a tissue-type prosthetic mitral heart valve that prevents suture looping and may also constrict the commissure posts of the valve. The holder may include two relatively movable plates, one of which attaches to the valve sewing on the inflow end of the valve ring and the other which attaches via sutures or similar expedient to the valve commissures on the outflow end. Separation of the plates places the sutures in tension and constricts the commissures. The sutures may be strands or filaments, or may be wider bands of flexible biocompatible material. If bands are used, they desirably cover the commissure post tips to further help prevent suture looping thereover. The flexible lengths of material extend directly between commissures of the valve, or may extending radially inward from each commissure to a central upstanding member. Desirably, a slide is created by the flexible lengths of material adjacent each commissure post, for example by crossing over suture filaments at or radially inward from the commissure posts. If an upstanding member is used, the lengths of suture extend axially beyond the commissure post tips to create a tent that wards off sutures that otherwise might loop around the tips during advancement of the valve along an array of pre-implanted sutures.
    • 改进的用于植入组织型假体二尖瓣心脏瓣膜的保持器,系统和方法,其防止缝合线环绕并且还可以约束瓣膜的连合柱。 保持器可以包括两个相对可移动的板,其中一个连接到阀环的流入端上的阀缝合,另一个通过缝合线或类似的方式附接到流出端上的阀连接。 板的分离使缝合线处于紧张状态并限制合缝。 缝合线可以是股线或长丝,或者可以是更宽的柔性生物相容性材料带。 如果使用条带,它们理想地覆盖连合后端,以进一步有助于防止缝合在其上。 柔性长度的材料在阀的连合之间直接延伸,或者可以从每个连接处径向向内延伸到中心直立构件。 期望地,通过邻近每个连合柱的柔性长度的材料产生滑块,例如通过在接合柱上或径向向内穿过缝合线。 如果使用直立的构件,则缝合线的长度轴向延伸超过连合后端,以产生防止缝合线的帐篷,否则,可以沿着预先植入的缝合线阵列推进阀门周围的尖端。

    • A holder for a flexible leaflet prosthetic aortic heart valve that is less bulky than earlier holders and minimizes obstructions to vision and working space around the valve to facilitate implantation thereof. The holder may have a central hub and three outwardly extending legs that connect directly and exclusively to tips of the commissures of the aortic heart valve for better tactile feedback when parachuting and seating the valve in the annulus. The legs are sized so that they do not overlap the commissure tips and therefore afford a better view of the sewing ring adjacent the commissures. The legs may be narrow in the midsection or split into two rails to increase visibility of the valve leaflets. The hub may be vaulted axially upward relative to the outer ends of the legs to further increase visibility of the valve. A more secure engagement between the central hub and a delivery handle is also provided to ensure the holder/handle connection does not become loose during suture placement through the sewing ring and fewer handle revolutions are required to screw in and unscrew the handle from the holder.
    • 用于柔性小叶假体主动脉瓣心脏的保持器,其比较早的保持器较不庞大,并且最小化围绕瓣膜的视觉和工作空间的障碍物以便于植入。 保持器可以具有中心毂和三个向外延伸的腿,其直接且专门地连接到主动脉心脏瓣膜的连合部的尖端,以在跳伞和将瓣膜安置在环中时获得更好的触觉反馈。 腿部的尺寸使得它们不与连合尖端重叠,因此可以更好地观察与连合缝相邻的缝合环。 腿可能在中部狭窄或分成两个轨道,以增加瓣膜单张的可视性。 轮毂可以相对于腿部的外端轴向向上凸出,以进一步增加阀的可视性。 还提供了中心毂和输送手柄之间更牢固的接合,以确保在通过缝合环的缝合线放置期间保持器/手柄连接不会松动,并且需要较少的手柄旋转以从保持器上拧下和松开手柄。

    • An improved holder and method for implanting a tissue-type prosthetic mitral heart valve that prevents suture looping and may also constrict the commissure posts of the valve. An upstanding or shaft member axially positioned on the holder causes the lengths of attachment sutures to extend axially beyond the commissure post tips to create a tent and prevent looping of any of an array of pre-implanted sutures around the tips during deployment of the valve. The shaft member may be axially movable such that it can be initially retracted and then actuated just prior to valve deployment. The shaft member may have notches on its distal tip for capturing the attachment sutures, which are crossed over along the valve axis to ensure engagement by the notches. The attachment sutures may be strands or filaments, or may be wider bands of flexible biocompatible material. If bands are used, they desirably cover the commissure post tips to further help prevent suture looping thereover. The flexible lengths of material extend directly between commissures of the valve, or may extending radially inward from each commissure to a central upstanding member.

    • Anatomical orifice sizers that are optimally proportional to an associated prosthetic device such as a heart valve, and methods of use are provided. The sizers are desirably slightly larger than the rigid mounting diameter of the corresponding heart valve.

    • An improved holder, system and method for implanting a tissue-type prosthetic heart mitral valve that constricts the commissure posts of the valve and allows the user to detach the handle of the holder prior to withdrawing the holder itself. The ability to remove the handle allows a surgeon greater access to suturing the prosthetic valve to the mitral annulus. The holder may include two relatively movable plates, one of which attaches to the valve sewing on the inflow end of the valve ring and the other which attaches via sutures to the valve commissures on the outflow end. Separation of the plates places the sutures in tension and constricts the commissures. An adjusting member or adapter is interposed between the handle and holder to enable separation of the two plates and removal of the handle. The adjusting member or adapter may be packaged with the valve and holder combination, or may be sold as a separate unit, possibly with the handle, so that prior art holders can be retrofit. Removable storage and handling clips secure the holder and heart valve assembly within a storage jar during transportation. A kit of a number of identical storage and handling clips and holders for different diameter tissue-type prosthetic heart valves may be provided.
