RNS
®
System User Manual
the Adaptive% = 50% and the sensed signal frequency = 20 Hz (50 ms
period), the stimulation frequency is delivered at 40 Hz (25 ms p-p interval)
If the neurostimulator cannot detect a stable frequency in the ECoG signal, or if the
calculated stimulation frequency is not between the user selected minimum and
maximum frequencies (M
IN FREQUENCY and MAX FREQUENCY), then the burst is delivered
at the selected default frequency (D
EFAULT FREQUENCY).
The following can be configured under the A
DVANCED SETTINGS button if a SYNC CHANNEL
has been selected on the R
ESPONSIVE THERAPY main tab.
Set S
YNCHRONIZATION to synchronous to deliver the first pulse of the burst in response to
the ECoG according to the F
IRST PULSE DELAY and the SYNCH SLOPE.
Note: Synchronization is only available to be delivered for B
URST 1 or PATTERN A in
T
HERAPY 1, and for BURST 1 in THERAPIES 2 – 5.
Note: If first pulse synchronization is selected as synchronous but the neurostimulator
is unable to synchronize to a waveform, the neurostimulator reverts to
asynchronous therapy delivery after 2 seconds.
4. Select R
ESPONSIVE THERAPY to be ENABLED.
5. Select the P
ROGRAM SETTINGS tab.
6. Select R
EVIEW CHANGES to view changes prior to programming.
7. Select the P
ROGRAM button.
REVIEWING REPORTS
Reports containing the RNS
®
Neurostimulator programmed settings, event history since last
interrogation, and ECoGs may be displayed for each programmer session. Reports are also stored on
the programmer for battery and impedance measurements, and saved detection sets.
Reviewing Reports and ECoGs
1. Go to the programmer MAIN MENU screen.
2. Select the R
EVIEW REPORTS button.
3. Choose patient/serial number.
4. Choose the report type to review.
Histograms are available when viewing interrogation reports. To view long term (up to 28 days of)
diagnostic information:
1. Select the H
ISTOGRAMS tab.
2. Select “Month by Day” or “Day by Hour”.
Note: Historic neurostimulator information, stored ECoGs, and real-time measurements are
available through the PDMS.
