    • A frame system for heart valve prosthesis. A first frame has at least three generally parallel legs each comprising a pair of rod portions connected at one end and diverging at the other end as lobes respectively connecting with rod portions of others of said legs. The lobes form an aperture therebetween and the legs are adapted to receive the margin of a valve leaflet between the rod portions thereof. Thus, the leaflet may be secured to two adjacent legs and the interconnecting lobe so as to have a free edge extending between said adjacent legs. A second frame is adapted to nest with the first frame and comprises a rod formed to be substantially congruent with the interconnecting lobes, whereby the leaflets may be secured to and between the frames.
    • 心脏瓣膜假体的框架系统。 第一框架具有至少三个大致平行的腿,每个腿包括一对杆部分,该杆部分在一端连接并且在另一端处以分别与所述腿部中的其他杆的杆部分连接的凸起分开。 叶片在它们之间形成孔,并且腿部适于在其杆部之间容纳瓣膜小叶的边缘。 因此,小叶可以固定到两个相邻的腿和互连瓣,以便具有在所述相邻腿之间延伸的自由边缘。 第二框架适于与第一框架嵌套并且包括形成为与互连凸角基本一致的杆,由此传单可以固定到框架之间并且在框架之间。
