ABSTRACT:
A blood vessel in a patient is severed by inserting a shaft through an incision in the patient, the shaft carrying first and second clamps. The first and second clamps are closed against the vessel in closely adjacent relationship to one another. Thereafter, the clamps are moved in generally opposing directions to sever the vessel at a location between the clamps. Each clamp carries a cauterizing pad for cauterizing the severed ends of the vessel.
