Abstract: A method and system for treating tissue with a surgical device includes the steps of displaying an image created by collecting imaging data from an imaging device, selecting at least one tissue target from the image, collecting image data and tracking the tissue target during at least one respiration cycle, determining the dwell position of the tissue target, and displaying an image created from image data collected with the tissue target at the dwell position. The method may further include determining the position and orientation of the surgical device with respect to the dwell position and indicating the trajectory of the surgical device on the display screen. The method may further include the steps of monitoring the respiration cycle, indicating when the tissue target is approaching the dwell position, positioning the surgical device in the patient based upon the dwell position and trajectory and treating the tissue target.

Abstract: The present invention provides a connector assembly including a connector for use in electrically connecting a surgical instrument to a power source, such as a generator. The connector generally includes an outer shell with a plurality of first and second electrical conductors disposed within the outer shell for providing the electrical connection between the surgical instrument and a cable leading to the power source. In one aspect of the present invention, the connector includes an isolation barrier disposed within the outer shell so as to separate each of the first electrical conductors from each of the second electrical conductors. In another aspect, the connector includes a keying feature in which the outer surface of the outer shell is modified so as to ensure that the connector may only be plugged into the generator a single way. This reduces the risk that the electrical conductors may be bent due to improper orientation during the insertion action.
