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.
