Glossary
Frequency. The frequency is the rate at which pulses are delivered which is expressed in Hz
(pulses/second).
Gain. ECoG signal amplification on one channel of the neurostimulator.
Impedance Measurement. The opposition of current flow between electrodes as determined by
measuring the voltage (Ohms) resulting from the delivery of a current pulse. A current pulse must be
applied to the patient in order to obtain this measurement.
Interrogate. The act of retrieving stored data and settings from the neurostimulator using the
programmer.
Lead Cap. The lead cap is intended to physically protect the proximal ends of implanted leads that are
not connected to the neurostimulator.
Lead ID. Numerical and/or alpha characters assigned to a lead to describe its anatomical location.
Lead Strain Relief. The lead strain relief is intended to mechanically support the proximal ends of the
lead at their exit point from the neurostimulator.
Line Length Detection Tool: See Power Change Detection Tool.
Live ECoG. ECoG data viewed in real-time through the programmer.
Long Episode. Initiate ECoG storage when a detected episode continues beyond a preset duration.
Magnet. The magnet suppresses RNS
magnet over the neurostimulator also triggers a diagnostic, and can also be programmed to trigger ECoG
storage.
Max Therapy Frequency. The max therapy frequency is an advanced setting available for each
responsive therapy burst. For an adaptive therapy burst (Adaptation = ON), the max therapy frequency
specifies the maximum stimulation frequency. 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.
Min Therapy Frequency. The min therapy frequency is an advanced setting available for each
responsive therapy burst. For an adaptive therapy burst (Adaptation = ON), the min therapy frequency
specifies the minimum stimulation frequency. 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.
Montage. Collective term used to describe the assignment of electrode labels and gain settings to the
amplifier channels.
Neurostim Info. Programmer display of measurements of the neurostimulator lead impedances and
battery voltage.
Neurostimulator. The RNS
controlled device that can amplify and analyze the patient's electrocorticographic activity, detect activity
from intracranial electrodes and deliver a short train of current pulses to the brain to attempt to interrupt
the detected activity.
Noise. 1. An event detector that identifies 60 Hz noise from selected detection channels. 2.
Environmental interference in the telemetry between the neurostimulator and wand/programmer.
