Glossary
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
2
calculated by the programmer. Charge densities greater than 25 µC/cm /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.
Configure detection. Analysis of detection settings using the programmer detection tools and retrieved
neurostimulator ECoG records.
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.
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 cortical strip lead is intended for subdural implant to provide an interface
through which electrical activity of the brain can be monitored and electrical stimulation may be delivered.
Craniectomy. Defect formed in the skull in order to implant the neurostimulator.
Cranial Prosthesis. The cranial prosthesis is intended to occupy the vacant craniectomy after the
neurostimulator has been explanted.
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.
Depth Lead. The depth lead is intended for implant into deep brain structures to provide an interface
through which electrical activity of the brain can be monitored and electrical stimulation may be delivered.
Detector channel. The amplifier channel of electrodes selected to detect ECoG activity.
Detection settings. Settings that combine patterns and detection tool settings in order to detect activity.
Detection status. A detection setting that controls the current state of the neurostimulator detection
function. Detection may be DISABLED, meaning detection is not active or ENABLED, meaning the
neurostimulator detection function is active and will monitor the sensed ECoG signal for events.
Detection tools. There are three (3) types of detection tools selectable for Pattern A or Pattern B event
detectors. The detection tools are: the bandpass tool, 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 Length. The amount of time stored for a programmer commanded ECoG record.
ECoG retrieval. Recovery of ECoG records from the neurostimulator memory. Retrieving ECoGs clears
the records from neurostimulator memory and stores them in programmer memory.
