ABSTRACT:
Apparatus for particular use in approximating the respective ends of two vas segments that are to be sutured together in a vasectomy reversal, the apparatus including two special clamp assemblies, each for gripping a separate vas segment, and a rotatable lead screw, to which the clamps are coupled, for controllably moving the clamps together. Each clamp includes two concave jaws that are movable toward each other to form a substantially cylindrical seat for conformably receiving and gripping the corresponding vas segment with a controllable pressure, whereby the segments are held in precise axial alignment, without any significant deformation. The two clamps are coupled to the lead screw via separate lead nuts disposed on oppositely threaded portions of the screw, whereby controlled rotation of the lead screw causes the clamps, and thus the vas segments being gripped, to be controllably approximated.
