VNS Therapy® Modes
The VNS Therapy® System can function in three different modes:
NORMAL MODE
In Normal Mode, the generator initiates intervals of stimulation at preset ON
and OFF times throughout the day. Specific stimulation parameters are set by
the healthcare provider.
MAGNET MODE
Magnet Mode is an on-demand stimulation that attempts to abort or
de-intensify an oncoming seizure or a seizure in progress. The patient or
caregiver initiates Magnet Mode by passing a VNS magnet over the
implanted generator.
AUTOSTIM MODE
Automatic stimulation, or AutoStim, is an optional feature in some generator
models. AutoStim delivers stimulation when the generator detects a rapid
relative heart rate increase (≥20%) that may be associated with a seizure.
This feature works in conjunction with Normal Mode and can be inhibited
using the VNS magnet.
