4. Clear tissue and bone debris away from the area surrounding the neurostimulator and lead
strain relief area.
5. Remove the lead strain relief from the neurostimulator and dispose.
6. Use the torque driver to loosen and remove the connector cover.
7. Remove the proximal lead end(s) from the neurostimulator port(s) and dispose of the old
connector cover.
8. Place a lead cap over the proximal contacts of the abandoned lead(s). The lead cap(s)
should be secured with a suture.
9. Flush the neurostimulator connector area (if necessary) to remove debris and dry area before
attaching the connector cover.
10. Hold the connector cover with the windows visible.
11. Place the lead proximal end into each port in the connector cover until the leads stop.
12. Confirm that the lead marker band is flush with the edge of the connector cover. If there is a
gap between the band and the edge of the connector cover seal, gently push the lead into the
connector cover port again until the lead stops.
13. Confirm that the lead contacts are fully visible in each window of the connector cover (Figure
14).
14. Place the connector cover on the neurostimulator and then loosely attach it to the
neurostimulator using the torque driver. Ensure that the leads remain completely inserted in
the connector cover.
Note: DO NOT use any tools other than the torque driver provided to secure the connector
cover in place.
15. Fully attach the connector cover to the neurostimulator by tightening the screw until the
torque driver clicks.
16. Place the lead strain relief over the proximal ends of the leads extending from the connector
cover and attach it to the post.
17. If using only one lead, be sure to place a connector plug in the vacant connector cover port.
Precaution: Connector Plug
A vacant port in the connector cover must be filled with a connector plug
(provided in the connector cover kit). There is an increased risk of
neurostimulator failure if a connector cover port is vacant.
18. Situate all capped, unconnected leads adjacent to the neurostimulator to facilitate easy
connection to the neurostimulator in the future.
19. Place any excess lead length in a sub-galeal pocket near the craniectomy, away from the
incision line.
Note: Leave sufficient slack in the lead adjacent to skull fixation points to relieve stress on
the lead.
20. Cover the wand with a sterile bag and position it over the neurostimulator.
21. Record the lead information, serial number(s), and corresponding neurostimulator port
number(s) on the P
ATIENT/PRODUCT tab of the programmer.
