Cortical Strip Lead Insertion
Note:
The cortical strip lead may be implanted in a manner similar to standard strip lead implants.
1. Make an incision in the scalp at or near the craniectomy location.
2. Perform a craniectomy to insert the strip lead.
3. Separate and dissect the dura around the area of desired cortical strip lead implant.
Precaution:
4. Retract or remove the stylet by pinching the stylet retainer, gently pulling the stylet away from
the lead body, and then withdrawing the stylet from the lead body the desired distance.
5. Carefully advance the cortical strip lead to the desired location.
6. Verify that the lead is in the desired anatomical position.
Cortical Strip Lead Stabilization
1. Fully remove the stylet.
Note:
DO NOT reinsert the stylet into the lead after it has been removed.
2. Leave approximately 10 mm of the lead inside the craniectomy to allow slack before securing
the lead to the skull. Cortical strip leads can be stabilized using the suture sleeves provided in
the lead kit. Place the suture sleeve on the lead body at the point where stabilization is
desired. Then use non-absorbable sutures to ligate the suture sleeve to the adjacent tissue to
stabilize the lead.
Precaution:
3. Place lead caps (provided) on the proximal end of unconnected leads.
Note: If implanting two leads that will not be connected, apply a non-absorbable suture tie to
one lead cap to distinguish the unconnected leads. Record the anatomical position of
the unconnected leads noting which lead has the non-absorbable suture marker.

Epidural Lead Placement
Leads placed epidurally may cause pain during electrical stimulation.
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.
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.
