Abstract: A surgery demonstration kit for comparing different surgical fastening tools and techniques includes a tube for simulating a vascular segment or other such body tissue, the vascular simulation tube being mounted to supports on a frame. The tube is cut to form at least one, and preferably two, side by side slits which are then repaired with the alternative tissue fastening instruments and techniques to be compared. A fluid conduit conducts fluid to the vascular simulation tube and the fluid is pressurized until one or both of the repaired slits begins to leak fluid. The kit is portable and the frame folds into a convenient carrying container.
