Abstract: A new use of an elastomeric material to which a stitchable covering is laminated. More specifically a thin knitted fabric may be laminated to an elastomeric material, optionally a foamed or porous material. Other materials are contemplated. In addition, the invention is directed to forms over which the simulated skin may be placed to reproduce the curvature of the human anatomy. One form has a varying curvature but is essentially square. The various curved portions simulated various curved portions of the skin that would be found on the abdomen, thigh, arm, chest or scalp. Another form is a mannequin simulating the face of a patient and which optionally has means for securing the simulated skin to the mannequin in a life-like configuration which include a simulated mouth and simulated eyes. These in turn assist in anchoring the simulated skin to the mannequin and also provide realistic guidelines for surgical practice.
