Figure 9: Removal of the insertion cannula, stylet, and stylet retainer from the lead.
4. Leave approximately 10-15 mm of the lead inside the burr hole, allowing slack in the lead
before securing the lead to the skull.
5. If using a burr hole cap/cover (not provided), follow the manufacturer’s instructions for use for
securing the lead to the burr hole.
6. If implanting more than one lead, mark the lead near the proximal lead contacts with a marker
(such as non-absorbable sutures) in order to identify the lead.
Precaution: Suture Sleeves
Suture sleeves are provided for use if sutures are used to stabilize the lead.
Suturing directly on the lead may cause lead body damage and malfunction.
7. Place lead caps (provided) on the proximal end of unconnected leads and place the excess
lead in a sub-galeal pocket near the burr hole.
Precaution: Sub-galeal Lead Placement
Wrapping the lead(s) on / around the neurostimulator or placing excess lead
near the neurostimulator may result in lead damage during subsequent
surgical procedures.
