Connecting the DBS Lead to the DBS Extension
DBS Extension
1. Check to ensure that the Setscrew is not restricting the entry port on the DBS
Extension connector by unscrewing the Setscrew one to two turns with the Torque
Wrench. Grip the DBS Lead next to the Retention Sleeve.
Note: The retention sleeve is easily distinguishable from the contacts by its extended
length.
2. Push the DBS Lead into the DBS Extension connector until the DBS Lead electrodes
line up with the DBS Extension contacts. Some resistance may be felt as each
electrode enters into the DBS Extension Connector. You should be able view the DBS
Lead electrodes as they pass through the DBS Extension Connector. Some additional
resistance may be felt as the last electrode aligns into place.
3. Visually check to ensure that the DBS Lead electrodes are aligned with the DBS
Extension contacts. If they are not aligned, continue to grip the DBS Lead next to the
Retention Sleeve and push to advance the electrodes into alignment with the DBS
Extension contacts. If necessary, back out the Lead slightly and then advance the
electrodes into alignment again, until proper alignment can be confirmed.
Note: Be sure to fully insert the DBS Lead into the connector so that the retention sleeve
is located under the Setscrew.
4. Do not tighten the Setscrew at this time.
5. Repeat steps 1 through 3 to connect the second DBS Lead to the second DBS
Extension.
