Impedance Tabs
[Stim>Impedance]
The
Impedance Button (Ω)
initiates impedance
measurements between adjacent electrode couples
in all of the configured leads and displays on the Imp
screen.
Group Workspace
Press the “Group” tab to access Group Workspace.
The Group Workspace is divided into four tabs (Groups)
by default named “Awake”, “Sleeping”, Exercising” and
“Sitting”). Each tab summarizes Group specific settings
for each of the implanted leads. These Groups can be
easily programmed as needed by the patient using the
Patient Programmer.
Lead Tabs [Group>Group Name]
Each Group can be configured by selecting the desired
tab.
•
Name:
The Group can be renamed here (free-
form text entry)
•
For Patient Use:
The Group will be displayed
on the Patient Programmer only if this box is
checked. Note that the currently active Group
must be checked/enabled.
•
Lead 1 through Lead 4:
The Stimulus
Response for each Lead within a Group can be
changed here. Stimulus Responses that have
been previously saved for that Lead will be
shown in the drop-down menu.
Periodic Stimulation
Periodic Stimulation can be toggled On or Off (green button indicates On). When On, the clinician can
program Stimulation On and Off durations independently. Once programmed, therapy will turn on and off
according to the programmed durations when:
• out of session, or
• in session in the Group Workspace (this allows the clinician to evaluate and optimize On/Off durations)
When in session in the Stim Workspace, Periodic Stimulation will be inactive (stimulation will remain ON)
to allow the clinician to optimize pulse parameters.
Rework Tabs
[Utility>Rework]
This screen provides one-button automation of the
normal TNS rework procedure:
The following steps are performed:
1. Impedance Check: Electrode impedances are
measured on all leads and compared against expected
load fixture values.
NOTE: the user should connect the standard load
fixture prior to this test. If the fixture is not available,
this step can be ignored and the remaining two
steps will still occur.
2. Set Nominal values: all patient values are cleared in
the NS and therapy settings are set to nominal.
3. Perform NS self-check: a self-test is started on
the NS. Upon next connection, the Programmer Alert
screen will show any detected NS problems.
Additional: The ‘Exit Hibernate’ and ‘Battery Attach’ dates are provided to assist the user in determining
when the TNS battery should be replaced.
Hibernate Tabs
[Utility>Hibernate]
‘Hibernate’ is used to keep the NS in a low-power state
after manufacturing, while in storage, prior to initial
clinical use. When connecting a Clinical Programmer
to a device in Hibernation, the user will have the option
to exit Hibernation. ‘Hibernate’ is normally not needed
after initial clinical use.
