Abstract
System (20) and related methods for performing surgical procedures and assessments, including the use of neurophysiology-based monitoring to determine nerve proximity and nerve direction to surgical instruments (30) employed in accessing a surgical target site.
Claims40
A system comprising:
- a surgical accessory having at least one stimulation electrode;
- and
- a control unit capable of electrically stimulating said at least one stimulation electrode on said surgical accessory, sensing a response of a nerve depolarized by said stimulation, determining a direction from the surgical accessory to the nerve based upon the sensed response, and communicating said direction to a user.
Dependencies are inferred from the claim text.
