An electrosurgical instrument including an elongated shaft and a non-conductive handle. The shaft defines a proximal section, a distal section, and an internal lumen extending from the proximal section. The distal section forms an electrically conductive tip and defines at least one passage for distributing fluid. Further, the shaft is adapted to be transitionable from a straight state to a first bent state. The shaft is capable of independently maintaining the distinct shapes associated with the straight state and the first bent state. The handle is rigidly coupled to the proximal section of the shaft. With this in mind, an exterior surface of the shaft distal the handle and proximal the distal section is electrically non-conductive. In one preferred embodiment, the shaft is comprised of an elongated electrode body surrounded by an electrical insulator.
What is claimed is: 1. A medical device for use in a medical procedure comprising: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
What is claimed is: 1. A medical device for use in a medical procedure comprising: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; anda 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.
