    • The present invention relates to a method of making clips which can be used to engage body tissue for the purpose of closing wounds. Such clips are generally annular in shape and have radially inwardly extending tines. The present invention first forms a precursor which, in one embodiment, has the tines extending radially outwardly from the annular body and then forms the clip by inverting the precursor such that the tines extend radially inwardly. In an alternate embodiment, the precursor is formed with an over-sized lateral dimension and then compressed inwardly to bring the tines closer together and to reduce the lateral dimension of the precursor. It is preferred to manufacture such clips from a superelastic alloy such as nickel-titanium, in which case the inverted or compressed precursor must be heated and quenched to heat set the clip in its final shape.
    • 本发明涉及一种制造夹子的方法,该夹具可用于接合身体组织以便关闭伤口。 这种夹子通常是环形的并且具有径向向内延伸的尖齿。 本发明首先形成前体,在一个实施方案中,前体具有从环形体径向向外延伸的齿,然后通过倒转前体形成夹子,使得尖齿径向向内延伸。 在替代实施例中,前体形成为具有超大尺寸的侧向尺寸,然后被向内压缩以使尖齿更靠近在一起并减小前体的横向尺寸。 优选从诸如镍钛的超弹性合金制造这种夹子,在这种情况下,必须加热和淬火反转或压缩的前体以将夹子热定型成其最终形状。
