Abstract

The present invention includes a device and method for vasculature simulation device comprising: a self-contained torso model comprising an aortic conduit; a first and second femoral conduit corresponding to a human femoral artery, wherein the inner bore of the human femoral artery seamlessly transitions into the inner bore of the aortic artery; a return conduit in fluid communication with the second end of the aortic conduit; a fluid pump in fluid communication with the return conduit of the aorta and a fluid reservoir, wherein the fluid reservoir and the pump are within the torso; a return conduit connected to the fluid reservoir for returning fluid to conduits; and a replaceable penetrable material in fluid communication with the first or the second femoral conduit, wherein the replaceable penetrable material is connected to the first or the second femoral conduits seamlessly.
