6 STOPPING STIMULATION
6.1 Magnet Mode
NOTE: Review this section with all patients.
NOTE: A commercial magnet with a pull force rated at 4.5 kg or greater is sufficient to stop
stimulation.
In the event that stimulation is too strong or becomes uncomfortable or there is some device
malfunction while the patient is at home, you or the patient may stop stimulation.
To stop stimulation, you or the patient must place the magnet over the patient’s chest where the
IPG is located and hold the magnet in place for at least 30 seconds. Stimulation is stopped for
as long as the magnet is placed over the IPG. If at home, the patient should contact their
physician (neurologist or physical medicine & rehabilitation [PM&R] doctor) or therapist for an
immediate appointment so that the device can be further tested.
CAUTION: In the event that stimulation continues once the magnet has been removed
from the patient’s chest, the magnet must be placed back over the patient’s chest where
the IPG is located to stop stimulation. The magnet should be held in place and the
patient’s physician contacted for further instruction. Stimulation will be stopped as long as
the magnet is held in place.
NOTE: During a patient’s first therapy session, verify that the patient can terminate stimulation.
Also verify that the patient is given an appropriate magnet to take home with them for this
use.
6.2 Therapist Trigger Mode
If you are using the VNS Pairing Therapy menu of the SAPS, stimulation may also be
terminated by selecting End Task (see Section 5.1.1: On-Demand Mode Therapy via the
VNS Pairing Therapy Menu and Figure 5.6).
Selecting End Task disables the Stimulate button.
6.3 Resetting the IPG / Safe Mode
In the event that the IPG reports a Safe Mode condition, the IPG must be reset to resume
programming or therapy. If the IPG reports a Safe Mode condition or needs to be reset for any
reason:
1. Contact MicroTransponder per Section 18: Information and Support.
2. After contacting MicroTransponder, select the Reset button to reset the IPG (see Figure
6.1).
