A portable medical simulation system and method employs an artificial patient with a built-in haptic interface device, with up to four carriages for engaging different diameter catheters. A catheter stabilizer between each carriage expands and contracts in an accordion fashion as the carriages move in relation to each other, preventing the catheter from bending and bowing. A contrast display visual effect derived from a particle emitter software tool simulates the release of radiopaque dye within a simulated vasculature system for display on a monitor. A computer software based system is used for generating haptic effects on the catheter through control signals passed to each of the carriage motors controlling translation movement of the catheter and magnetic particle brakes controlling rotational movement of the catheter.
