Craniectomy Placement
The recommended location of the neurostimulator is in the parietal skull. However, the
neurostimulator may be implanted anywhere in the skull in a position that achieves a good contoured
fit and allows the neurostimulator to sit flush with the cranial surface. The neurostimulator can be
inserted into the ferrule in only one orientation and the leads exit the connector cover from only one
direction. Review the neurostimulator orientation and lead exit point prior to creating the craniectomy.
The location and orientation of the incision line relative to the RNS
®
Neurostimulator device should be
planned to facilitate future neurostimulator replacement. Consider the following:
•
The portion of the incision that will need to be re-opened to replace the neurostimulator
should not traverse the lead(s).
•
The incision should be relatively close to the ferrule clamp and connector cover for ease of
access.
•
The incision should allow for good exposure of the neurostimulator and the connector cover
area if necessary.
