  • Patent number: 4548202
    Abstract: Various fasteners are provided to hold together portions of mammalian tissue. The fasteners include fastening members with spaced-apart legs adapted to be passed through the tissue portions. One embodiment of the fastener has a mesh-like receiver around each leg for engaging the legs of another identical fastening member inserted from an opposite side of the tissue portions. In other embodiments, the receiver is a separate element and is applied to a side of the tissue portions opposite the fastening member to engage the legs of the fastening member. The receiver may have a variety of forms. A number of structures are disclosed for effecting engagement of the fastening member legs with the receiver.

  • Patent number: 4440170
    Abstract: A pistol-type surgical instrument for applying ligating clips to blood vessels and other tubular ducts in remote locations which are substantially inaccessible to conventional forceps-type appliers. Tubular jaw assemblies of various lengths may be mounted on the pistol-grip handle of the instrument, and the mounted jaw assembly is fully rotatable to permit orientation of the clip applying jaws. The jaws are preferably at right angles to the axis of the tubular jaw assembly, but may be slanted forward or rearward up to about 20 degrees.
