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.

A method of severing a blood vessel in a patient comprising the steps of:
- A. inserting a shaft through an incision in the patient, the shaft carrying first and second clamps;
- B. applying the first and second clamps to the vessel in closely adjacent relationship;
- and then
- C. moving the first and second clamps in generally opposing directions to sever the vessel at a location between the clamps.
Apparatus for severing a blood vessel, comprising:
- a shaft adapted to be inserted into a patient;
- first and second clamps carried by the shaft;
- and
- a displacement mechanism carried by the shaft and arranged to close the first and second clamps against the blood vessel at respective locations disposed adjacent on another, and for moving the first and second clamps in generally opposite directions to sever the vessel.
