Pattern detection settings are used by the RNS
®
Neurostimulator to recognize epileptiform activity as
defined by the physician. To configure pattern detection means to select specific ECoG patterns to be
detected, and then to program the system to detect these patterns. Configuring pattern detection is a
prerequisite for electrical stimulation therapy, but it does not require you to enable therapy.
Note: A pattern defines the type of ECoG activity to be detected.
Note: When defining or modifying a detection set, the programmer and the PDMS are able to
automatically simulate detection on all ECoGs stored for a patient. Simulation is displayed for
groups of six ECoGs at a time, with the user able to navigate through all ECoGs for that patient.
Note: Although detection sets can be created and modified using the PDMS either in a web
browser or on the programmer, only the programmer can be used to program the new settings
into the neurostimulator. When you select a new detection set that was created on the PDMS, it is
not necessary to re-run simulation on the programmer.
Configuring pattern detection has three phases:
•
Phase 1: Select a Default Detection Set upon First Use
, you select one of the
three default detection sets to gather an initial collection of ECoGs. This is usually configured and
programmed in the operating room immediately after implantation.
•
Phase 2: Define a Pattern Detection Set
, after initial ECoGs have been stored, you
review the stored ECoGs and identify the specific ECoG patterns to be detected. Using the
SimpleStart Feature, the system provides a starting point for this process. It is a tool to assist
you
as you exercise clinical judgment to define detection settings. It suggests a starting point
only. It
does not preempt nor replace your clinical judgment. This is usually programmed at the
first visit
post-implantation.
•
Phase 3: Customize Pattern Detection
on page
, you repeat the process of reviewing stored
ECoGs and adjusting the parameters of each pattern to optimize detection of ECoG activity for
this patient. This is programmed at any visit after phase 2.
Note: For all settings, changed settings are indicated by blue buttons. Gray buttons indicate
settings have not changed.
To put these three phases in context:
Immediately after implantation of the neurostimulator, you select a default detection set in
Phase 1,
in
order to collect ECoGs with activity of interest specific to the patient, and ECoGs with baseline activity.
After collecting sufficient ECoGs, you identify the specific electrocorticographic patterns to be detected
and then, in
Phase 2,
the system provides a starting point for establishing a patient-specific detection set.
You may then modify the parameters of the suggested starting detection set to make detection more or
less sensitive, or to detect earlier or later.
