Removing or Replacing the DBS IPG
1. Turn off the IPG.
2. Palpate the pectoral or abdominal area to locate the IPG.
3. Surgically open the pocket where the IPG is located. The incision should be large enough to
remove the IPG from the pocket. Be careful not to damage the implanted components to allow
for proper analysis following explant.
4. Remove the IPG from the IPG pocket.
5. Using the Torque Wrench, unscrew the IPG Header Setscrews to release the Lead Extensions.
Caution: Loosen the Setscrew only as much as is necessary to remove the Lead Extension.
Loosening the Setscrew too much will cause it to fall out.
Note: To tighten the Setscrew, rotate the Torque Wrench clockwise. To loosen the Setscrew,
rotate the Torque Wrench counterclockwise.
6. Remove the Lead Extensions from the IPG.
7. If the Lead Extension will remain implanted:

subsections (as applicable).

incision.
