The invention provides a system and method for harvesting a vessel section. The system comprises an endoscope, a harvesting tool, and an elongated instrument including a transparent distal nose portion, an intermediate portion having a recessed working area, and a proximal portion having at least one passageway to allow the harvesting tool access to and the endoscope visualization of the working area. The method includes making an incision at a point corresponding to the proximal end of the vessel section being harvested. The endoscope is positioned in the nose portion of the instrument, and instrument is inserted through the incision and partially into the body. Tissue is bluntly dissected away from the vessel using the nose portion. The endoscope is repositioned adjacent to the recessed working area, and a harvesting tool is inserted into the working area through the passageway and visually monitored with the endoscope.
