System Programming Manual
Connector Plug.
The connector plugs are used to fill any ports on the connector head of the
neurostimulator that are not in use.
Cortical Strip Lead.
The NeuroPace
®
Cortical Strip Lead lies on the surface of the brain (cortex) and can
detect the electrical activity of the brain and deliver stimulation.
Cranial Prosthesis.
The cranial prosthesis is intended to occupy the vacant craniectomy after the
neurostimulator has been explanted.
Craniectomy
. Defect formed in the skull in order to implant the neurostimulator.
Craniectomy Template.
The craniectomy template is intended to be used as a pattern to mark and
delineate the shape of the ferrule on the skull prior to making the craniectomy.
Current.
The amplitude of current that will be delivered in each phase of a current pulse.
Delay.
A programmed delay in the delivery of the first pulse of a burst, measured from the time of
synchronizing to a signal peak.
Default Therapy Frequency.
The default therapy frequency is an advanced setting available for each
responsive therapy burst. For an adaptive therapy burst (Adaptation = ON), if the calculated stimulation
frequency does not fall between the programmed min and max frequencies, then the stimulation is
delivered at the default therapy frequency.
Delay.
A programmed delay in the delivery of the first pulse of a burst, measured from the time of
synchronizing to a signal peak.
Depth Lead.
The NeuroPace
®
Depth Lead is implanted into the brain and can detect the electrical activity
of the brain and deliver stimulation.
Detection Settings.
Settings that combine patterns and detection tool settings in order to detect activity.
Detection Tools.
There are three (3) types of detection tools selectable for Pattern A or Pattern B
detectors. The detection tools are: the bandpass tool, power change tool (also known as the line length
tool), and area tool.
ECoG.
Electrocorticogram. Electrical activity derived directly from the cerebral cortex. Also used to
describe the neurostimulator or programmer stored record of this activity (e.g. “ECoG record”).
ECoG Activity.
ECoG activity refers to activity which is detected by the neurostimulator using one of the
event detectors.
ECoG Trigger.
The type of neurostimulator activity selected by the user to result in the capture of an
ECoG record if the activity occurs.
Elective Replacement Indicator (ERI).
The ERI indicator is displayed on the programmer to notify the
user that the neurostimulator is approximately three months prior to end-of-service (EOS).
Neurostimulator elective replacement is suggested at a battery voltage equal to the ERI.
End-Of-Service (EOS).
End of service is the point in service at which the battery level is still sufficient to
allow operation, however some features may be lost.
Event.
Activity detected by the neurostimulator. Events are considered any of the following: long
episodes, pattern A, pattern B, responsive therapy, noise or saturation.
Ferrule.
The ferrule is intended to be installed in a craniectomy to secure and mechanically support the
neurostimulator in the cranium.
Ferrule Clamp.
The ferrule clamp is used to secure the neurostimulator to the ferrule.
