Abstract
A leg model, designed to teach endoscopic saphenous vein harvesting, is provided that accurately models the anatomy of the saphenous vein in the human thigh, and closely approximates the subcutaneous tissues in a human. The subcutaneous tissue is formulated and manufactured such that the saphenous vein adheres to the subcutaneous tissue to simulate the adhesion in a human leg. The model includes a reusable base and a replaceable single use insert. The base is size and configured to receive the insert. The tray can include a slit located at a point along its length that permits the ends of the tray to rotate about the slit so that the ends can be bent with respect to one another.
