Explanting or Replacing the DBS System

Explanting the DBS System

If the entire DBS System (Stimulator, Extensions, and DBS Leads) will be explanted, then the
DBS Leads should be removed first (as described below) followed by the Lead Extensions, then
the IPG. This order will reduce the potential spread of infection toward the incision on the skull.
However, if only a single component will be replaced, follow the instructions below for that specific
component.
Removing the DBS Leads
Warning: When explanting the Boston Scientific DBS System, the DBS Lead should be pulled
from the site above the ear and not the site near the burr hole, to avoid a potential
spread of infection toward the incision on the skull.
1. Turn off the IPG.
2. Palpate the scalp to locate the Burr Hole Cover.
3. Make an incision near the Burr Hole Cover to expose it and the DBS Lead. While making the
incision, be careful not to damage or cut the DBS Lead or Suture Sleeve.
4. Cut the DBS Lead approximately 2 to 3 cm from the Burr Hole Cover, leaving enough length to
grasp the DBS Lead.
5. If applicable, see the "Removing the Burr Hole Cover" section of this manual to remove the Burr
Hole Cover.
6. Slowly and gently retract the distal portion of the DBS Lead from the neural tissue, pulling as
perpendicular to the skull as possible. Resistance should be minimal when retracting the DBS
Lead.
7. Palpate the region under the scalp to locate the Lead Extension Connector.
8. Create an incision to expose the DBS Lead and Lead Extension Connector. Be careful not to
damage the implanted components to allow for proper analysis after explant.
9. Loosen the Setscrew on the Lead Extension Connector using the Torque Wrench provided.
Note: Ensure that the Torque Wrench is fully inserted before loosening the Setscrew. To
tighten the Setscrew, rotate the Torque Wrench clockwise. To loosen the Setscrew,
rotate the Torque Wrench counterclockwise.
10. Remove the DBS Lead from the Lead Extension.
11. Gently pull the remainder of the DBS Lead through the incision behind the ear.
The DBS Lead should be pulled from the site behind the ear and not the site
Warning:
near the burr hole to avoid a potential spread of infection toward the incision on
the skull.
12. To replace the DBS Lead, see the "Implanting the DBS System" section of this manual and
repeat all subsections (as applicable).
