System for permanent electrode placement utilizing microelectrode recording methods
First Claim
1. A system for recording and stimulating excitable neural tissue, the system comprising:
- a microelectrode, configured and dimensioned to be completely passable through a lumen along the axial length of a stimulating lead, commencing from either a first opening or a second opening of the stimulating lead; and
a removable connector for attaching and detaching the microelectrode from the stimulating lead, the removable connector including a locking mechanism.

Abstract
A lead stimulation/recording system is provided, which is a combination of a permanent DBS stimulating lead and a recording microelectrode. The DBS lead has a lumen extending from the proximal to the distal end of the lead, the lumen having an opening on each end of the lead. The microelectrode is configured and dimensioned to be insertable into the DBS lead from either the distal or proximal opening of the DBS lead, thereby permitting the microelectrode to be placed before, concurrently with, or after placement of the DBS lead. In addition, the system may be used with known microelectrode recording systems and methods of inserting the electrodes, such as the five-at-a-time method, the dual-microdrive method, or the single microdrive method.
