Vercise™ DBS System Revisions &
Explantation
If the entire Vercise DBS System (Stimulator, DBS Extensions, and DBS Leads) is to
be removed, then the DBS Leads should be removed first (as described below) followed
by the DBS Extensions, and lastly the Stimulator. This order should reduce the potential
spread of infection toward the skull opening.
Explanting the DBS Lead
WARNING: When explanting the Vercise 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 skull opening.
1. Turn off the Stimulator.
2. Palpate the scalp to locate the mini plate.
3. Make an incision near the mini plate to expose the mini plate and DBS Lead.
Be careful not to damage or cut the DBS Lead or suture sleeve.
4. Cut the DBS Lead at a distance about 2‑3 cm from the mini plate, leaving enough
length to grasp the Lead.
5. Unscrew the screws anchoring the mini plate and gently remove the mini plate.
6. Use appropriate methods to remove the DBS Lead from the adhesive.
7. Slowly and gently retract the DBS Lead from the neural tissue, pulling as close to
perpendicular to the skull as possible. The DBS Lead should experience minimal
resistance when retracted.
8. Palpate the region under the scalp to locate the DBS Extension connector.
9. Create an incision to expose the DBS Lead and DBS Extension connector. Be careful
not to damage the implanted components to allow for proper analysis following
explant.
10. Loosen the connector Setscrew on the DBS Extension using the Torque Wrench
provided.
Note: Be sure to fully insert the Torque Wrench before loosening the Setscrew.
Note: To tighten the Setscrew, rotate the Torque Wrench clockwise. To loosen the
Setscrew, rotate the Torque Wrench counterclockwise.
11. Remove the DBS Lead from the DBS Extension.
12. Gently pull the remainder of the DBS Lead through the incision behind the ear.
WARNING: The DBS Lead should be pulled from the site behind the ear and not the
site near the burr hole to avoid a potential spread of infection toward the
skull opening.
