ABSTRACT:
A cannula includes a tubular body having proximal closed end and distal blunt end, at least one lumen extending the length of the body, an endoscope having a lighted, viewing end disposed in the lumen near the distal end of the body, and a transparent, tissue separating member substantially covering the distal end of the body. The tissue separating member has a blunt tip disposed from and of the end distal to the body. A method of using such a cannula separates tissue to form an elongated cavity along the course of a small blood vessel and subsequently harvesting the blood vessel.
