Securing The Dbs Lead - Boston Scientific DBS Vercise Mode D'emploi

Securing the DBS Lead

Once the DBS Directional Lead has been placed, it should be secured.
CAUTION: While securing the Lead, use care not to move it.
1. Remove the Lead Stop by unscrewing the screw and detaching the Lead Stop from the Lead.
2. Slowly retract the cannula to just above the burr hole by sliding it over the proximal portion of the Lead.
Be careful not to move the 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 Vercise
System. (An appropriate commercially available filler may also be used.
4. Remove the stylet.
CAUTION: Do not reinsert the stylet into the Lead while the Lead is in the brain, as this may cause patient harm.
5. Remove the stereotactic frame and microdrive system.
6. If the Stimulator will be implanted during a separate surgery, prepare the Lead for the Stimulator
implantation procedure.
a. Insert proximal end of the Lead into the Lead Boot until it stops (Figure 7).
b. Place a Suture Sleeve on the left Lead to differentiate the Leads.
Note: Be sure to fully insert the proximal tip of the Lead into the Lead Boot (see below) so that the retention sleeve
is located under the Setscrew.
Note: The retention sleeve is easily distinguishable from the contacts by its length (Figure 8).
c. Pass the Torque Wrench through the slit in the septum located on the top of the Lead Boot.
d. Tighten the Setscrew until the Torque Wrench clicks, indicating the Setscrew is fully secured.
