Vercise™ DBS Leads Directions for Use
10. Evaluate DBS Lead placement:
(a). Evaluate whether stimulation is appropriate to reduce symptoms.
(b). Adjust the DBS Lead location or stimulation parameters if necessary.
Note: The stylet should remain in place throughout DBS Lead insertion and adjustments.
WARNING: High charge density can cause permanent tissue damage. The Clinician
Programmer will limit the stimulation parameters to safe values.
WARNING: Increasing the number of DBS Lead penetrations increases the probability
of hemorrhage. The necessity for an acute DBS Lead revision should be
minimized using techniques of target localization, such as microelectrode
recordings and imaging, to correctly place the DBS Leads on the first attempt.
11. Turn off the External Trial Stimulator 2.
WARNING: A sudden increase in stimulation may occur if External Trial Stimulator 2 is ON
while disconnecting the OR Cables.
12. Disconnect the OR Cable and Extension from the proximal end of the DBS Lead.
13. Verify that the DBS Lead has not moved from the desired location.
Securing the DBS Lead
Once a DBS Lead has been placed, it should be secured.
CAUTION: While securing the DBS Lead, use care not to move it.
1. Remove the Lead Stop by unscrewing the screw and detaching the Lead Stop from the DBS
Lead.
2. Slowly retract the cannula to just above the burr hole by sliding it over the proximal portion of
the DBS Lead. Be careful not to move the DBS Lead.
Note: The descriptors "proximal" and "distal" use the Stimulator as the reference throughout this
manual.
3. Fix the Lead in place. The SureTek™ Burr Hole Cover Kit is recommended for use with the
Boston Scientific DBS System. (An appropriate commercially available filler may also be used.
4. Remove the stylet.
CAUTION: Do not reinsert the stylet into the DBS Lead while the DBS Lead is in the brain,
as this may damage the DBS Lead and/or cause patient harm.
5. Remove the stereotactic frame and microdrive system.
1 DBS Lead secured and tested utilizing Biomet Mimix QS bone filler; a Stryker 12 mm titanium mini plate, Stryker titanium
screws, and a Boston Scientific 1 cm split suture sleeve. Data on file.
