Abstract
A system for placement of biocompatible electrodes in an opening formed in a patient's body part, such as DBS electrodes inserted into a patient's skull during surgical procedures in the brain. The system includes a coupled catheter and annulus. The catheter includes a guide tube having at least three cooperating guide elements configured to releasably fit together and collectively form a continuous lumen through the catheter that is dimensioned to receive an electrode therein. The annulus is configured to be placed in the opening formed in the patient's body part, and to receive the catheter therethrough. A track mechanism is used to operably couple the catheter to the annulus.
