Neurostimulator Interrogation
The sterile, packaged neurostimulator should be interrogated using the programmer prior to

2. Place the wand over the neurostimulator, which is visible from the bottom (clear side) of
the neurostimulator sterile packaging tray.
3. Select the

on the summary screen. If interrogation fails or the
battery voltage is < 2.85 V, return the neurostimulator to NeuroPace, and continue the
procedure with another sterile, packaged neurostimulator.
To manually measure battery voltage after interrogating:
1. Go to the

Opening the Sterile Product Package
Prior to opening the sterile packaging, inspect for any damage or breach in package seal
integrity. If the packaging appears to be wet, punctured, or damaged, the contents may no longer
be sterile. Product(s) with damaged packaging should be returned to NeuroPace for replacement.
Packages containing sterile product(s) should be opened into a sterile surgical field. Products
should not leave the sterile surgical field once the package is opened.

Bone screws
It is recommended that 1.5 mm diameter, 4 mm long bone screws (not provided) be used to
secure the ferrule to the skull. If necessary, 5 mm or 7 mm long bone screws may be used. If the
1.5 mm diameter screws do not securely anchor the ferrule in the skull, 1.8 mm diameter screws
should be used.
