ABSTRACT:
The present invention provides a multiple cannula assembly which includes an inner cannula having a first balloon for making an elongated cavity by progressive dissection, an endoscope for visually monitoring the dissection, and an outer cannula having a second balloon for enlarging the elongated cavity. The inner cannula is independently movable from the outer cannula and is reversibly extendible beyond the distal end of the outer cannula. The present invention also includes a method of using such a cannula assembly for dissecting an elongated cavity along the course of a small blood vessel and subsequently harvesting the blood vessel.
