Abstract
A catheter includes an electromechanical polymer (EMP) actuator disposed in a steerable tip at the distal end of the catheter. When activated, the EMP actuator deflects the steerable tip through an angle between 0 and 270 degrees, thus permitting the operator to steer the steerable tip through the vasculature. The steerable tip also has at least a first relatively stiff region and a second relatively flexible region, and the EMP actuator is provided next to the first relatively stiff region so that the steerable tip may toward the flexible region when activated. In one implementation, an external interface allows a user to select by name one of many sets of control signals, with each set of control signals being signals calibrated for configuring the catheter to mimic a known catheter.
