Abstract
A system and method for identifying a stimulation location on a nerve is disclosed. The system includes an image-based navigation interface used to facilitate advancing a stimulation element within a patient body toward a target nerve stimulation site. Using the system one determines, separately for each potential target nerve stimulation site, a neuromuscular response of muscles produced upon applying a stimulation signal at the respective separate potential target stimulation sites. The image-based navigation interface is configured to display a graphic identification of which muscles were activated for each respective potential target nerve stimulation site upon applying the stimulation signal.

92. A system for placing a stimulation element, the system comprising:
-
a neuromuscular response evaluation module including; a stimulation engine configured to apply an electrical stimulation signal to a patient body portion via a stimulation element; and a muscle response module configured to determine a response of a muscle to application of the stimulation signal; a probe interface including an array of ports; an array of sensor probes, each removably connectable to a respective one of the ports and removably attachable to a body portion corresponding to the muscle, the sensor probe configured to sense the muscle response; and a graphical user interface including; an image display module configured to display at least one image of the patient body portion; and a muscle identifier module configured to visually identify, superimposed on the at least one image, which muscles were activated for each respective application of the stimulation signal. - View Dependent Claims (93, 94, 95, 96, 97, 98, 99, 100, 101, 102, 103, 104, 105, 106, 107)

108. A surgical interface system comprising:
a graphical user interface including; an image display module configured to display at least one image of a patient body portion; a muscle identifier configured to visually identify, superimposed on the at least one image, muscles that are activated upon application of a stimulation signal to a nerve; a nerve-muscle response index configured to display a first listing of potential target nerves and a second listing of muscles, wherein each listed muscle is correlated to a respective one of the potential target nerves that innervate the respective listed muscle, wherein upon detecting activation of one of the listed muscles, the corresponding target nerve in the first listing responsible for activation of the nerve is highlighted; and a functional result module configured to display at least one image of at least one functional result associated with the patient body portion, the at least one functional result produced via activation of a respective one of the muscles in the second listing. - View Dependent Claims (109, 110, 111, 112, 113)
