Method and system for identifying a location for nerve stimulation
First Claim
1. A system for placing a stimulation element, the system comprising:
- a neuromuscular response evaluation module including;
a stimulation engine to apply an electrical stimulation signal to at least one nerve within a patient head-and-neck portion via a stimulation element; and
a muscle response portion to determine, via at least sensing in association with at least one sensor probe, a response of at least one muscle in the patient head-and-neck portion to application of the stimulation signal;
a probe interface including an array of ports;
an array of sensor probes, including the at least one sensor probe with each sensor probe removably connectable to a respective one of the ports and removably couplable relative to at least one muscle in a patient head-and-neck portion, the sensor probe to at least partially implement the sensing of the response of the at least one muscle; and
a graphical user interface;
a controller including a processing unit; and
a non-transitory memory storing instructions, executable via the processing unit, to;
display, on the graphical user interface, at least one internal image of the patient head-and-neck portion; and
visually identify, superimposed on the at least one internal image on the graphical user interface, which muscles in the head-and-neck portion, including the at least one muscle, were activated for each respective application of the stimulation signal to at least one nerve in the head-and-neck portion.

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.

21. A surgical graphical user interface comprising:
-
a display portion; a controller, including a processing unit; and a non-transitory memory storing instructions, executable via the processing unit, to; display, on the display portion, at least one internal image of a patient head-and-neck portion; visually identify, superimposed on the at least one internal image on the display portion, muscles in the head-and-neck portion that are activated upon application of a stimulation signal to at least one nerve in the head-and-neck portion; display, via a nerve-muscle response index on the display portion, a first listing of potential target nerves, including the at least one nerve, 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 display on the display portion at least one image of at least one functional result associated with the patient head-and-neck portion, the at least one functional result produced via activation of a respective one of the muscles in the second listing. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28)
