2115766 9401062 PCTABS00030 A method of creating a simulated aorta (10) patterned from a natural aorta and having a preselected amount of compliance (12-1, 12-2, 12-3) is disclosed. The dimensions of a simulated aortic root (10) patterned according to the dimensions of a natural aorta are first selected and a mold provided. The amount of circumferential compliance (12-1, 12-2, 12-3) desired in the simulated aorta (10) is then selected, based on natural circumferential compliances. A material such as silicone rubber formed of an elastomer and a filler is used to form the aorta (10), the durometer of the material being varied by varying the relative amount of the components, to provide the selected amount of circumferential compliance in a simulated aorta (10) having the selected dimensions. The aorta (10) is then formed curing the material in the mold for about 24 hours. Groups of simulated aortas (10) so produced, sometimes having different sizes and/or compliances are also disclosed. A method of testing non-stented valves (14) using the aortas (10) is included.
