  • Patent number: 8736212
    Abstract: A robotic catheter control system includes a plurality of electric motors. Diagnostic logic automatically detects motor runaway fault conditions based on the current motor position, the target motor position and a predetermined tolerance parameter. Fault conditions include overshoot, movement in the a non-prescribed direction, exceeding a prescribed maximum motor speed and exceeding a prescribed maximum motor acceleration. The diagnostic logic terminates operating power to the electric motor when a fault condition is detected for any one of the motor. An error message is generated to notify the operator of the fault.

  • Publication number: 20130165946
    Abstract: An apparatus for a robotically controlled medical device guidance system comprises a manipulator assembly and a medical device cartridge. The manipulator assembly includes a housing, an electrical port having a first end configured for mating with a complementary electrical connector of a cable, and a manipulation base disposed within the housing and including an electrical interface. The electrical interface is electrically connected to a second end of the electrical port. The cartridge is configured to be removably attached to the manipulation base. The cartridge includes an electrical interface configured to electrically contact the electrical interface of the manipulation base when the cartridge is attached to the base, and a medical device associated therewith. The medical device includes a sensor and a corresponding lead wire. The lead wire is electrically connected to and between the sensor and the electrical interface of the cartridge.
