摘要:
The clips (18) of the present invention include two closure members (22, 24) joined by at least two spaced central connecting members (36, 38). The clips (18) are designed such that the at least two central connecting members (36, 38) extend through the inclined PFO tunnel and the two closure members (22, 24) compress the overlapping layers of septal tissue, i.e. septum primum and septum secundum, together to close the PFO tunnel. The clips (18) of the present invention take various forms depending, in part upon the distribution of force required to close a given PFO. Thus, embodiments of the closure members (22, 24) include arcuate peaks (26), loops (46, 48), and prongs (96, 98). In yet other embodiments, the closure members (22, 24) include centering elements (49) for centering the device in the desired delivery location and a tissue scaffold (108).
摘要(中):
本发明的夹子(18)包括由至少两个隔开的中央连接构件(36,38)连接的两个闭合构件(22,24)。 夹子(18)被设计成使得至少两个中央连接构件(36,38)延伸穿过倾斜的PFO通道并且两个闭合构件(22,24)压缩隔膜组织的重叠层,即隔膜和隔膜 继续共同关闭PFO隧道。 本发明的夹子(18)部分取决于关闭给定PFO所需的力的分布而采取各种形式。 因此,封闭构件(22,24)的实施例包括弧形峰(26),环(46,48)和叉(96,98)。 在又一些实施例中,闭合构件(22,24)包括用于将设备定心在期望的递送位置中的定心元件(49)和组织支架(108)。
