Adapt Channel.
The adapt channel is an advanced responsive therapy setting. The neurostimulator will
monitor this channel from which to calculate the adaptive stimulation frequency. This channel is used for
all adaptive bursts.
Adapt Min Amplitude.
The percentage of the detected signal amplitude to be used as the minimum
therapy amplitude.
Adaptation.
The neurostimulator may be programmed to deliver the pulse interval for a responsive
therapy burst by adapting to the electrographic signal by a selected percentage.
Anode.
The positive pole of an electrode selected for stimulation.
Area Detection Tool.
The area detection tool measures the area under the curve of an ECoG signal.
Asynchronous Pulse.
Delivery of the first pulse in a burst independent of the ECoG activity.
Bandpass Detection Tool.
The bandpass detection tool measures the approximate frequency of the
signal based on the duration and amplitude of waveform segments.
Battery Measurement.
The neurostimulator battery voltage may be measured interactively through the
programmer.
Burr Hole.
Hole made in the skull used for the insertion and securing of implanted cortical and/or depth
leads.
Burr Hole Cap.
The burr hole cap is intended to secure the leads in relation to the cranium.
Burr Hole Cover.
The burr hole cover is intended to secure the leads to the burr hole cap.
Burst.
An individually programmed group of one to many pulse(s) of current delivered by the
neurostimulator.
Burst Duration.
The amount of time during which a burst will be delivered by the neurostimulator.
Burst 1.
The first burst of stimulation delivered within an individual responsive therapy. This burst may be
delivered asynchronously or synchronously.
Burst 2.
The second burst of stimulation delivered within an individual responsive therapy. This burst may
be programmed ON or OFF for each therapy and will always be delivered asynchronously following Burst
1 of the therapy if programmed ON.
Calculated Charge Density.
The charge density of a selected and/or programmed stimulation is
calculated by the programmer. Charge densities greater than 25
µ
C/cm
2
/phase are not allowed to be
selected or programmed into the neurostimulator.
Can.
“Can” is used to describe the neurostimulator titanium body. The can may be used as either an
anode (+) or cathode (–) in a stimulation pathway.
Cathode.
The negative pole of an electrode selected for stimulation.
Channel.
The amplifier channel of electrodes selected to detect ECoG activity.
Connector Cover.
The connector cover is intended to secure the proximal lead contacts and lead strain
relief to the body of the neurostimulator.
Connector Cover Port.
The connector cover ports contain the point of contact between the proximal end
of the lead(s) and the neurostimulator. The connector cover contains two (2) ports, one for each lead.
