  • a manually graspable handle;

    an elongated shaft projecting from the handle, the shaft being sized and shaped to be positioned through a small incision in the chest of a patient and defining a proximal section comprising a rigid, elongated metal tube and a distal section comprising metal and a rounded distal tip portion adapted to be slid relative to tissue, the shaft including a joint comprising a pin that moveably couples the distal section to the proximal section thereby allowing the distal section to pivot relative to the proximal section;

    a non-conductive material surrounding at least a portion of the elongated shaft;

    a remote actuator proximal the distal section for selectively controlling the actuation of the joint;

    a power source comprising a battery;

    a light located on the distal section and electrically coupled to the power source; and

    a switch located on the medical device for activating the delivery of electrical power from the power source, wherein the light is visible when power is being delivered.
