5 DELIVERING PAIRED VNS
™
After choosing and saving device settings, you can start a stimulation session. The On-Demand
Mode and Entire Session VNS Scheduler menus allow the user to configure the method by
which the Vivistim
®
System delivers stimulation.
• The On-Demand Mode menu allows stimulation trains to be individually triggered during a
session by the therapist (found in Section 5.1: On-Demand Mode Menu).
• The Entire Session VNS Scheduler menu allows the stimulation trains for an entire
therapy session to be programmed in advance (found in Section 5.2: Entire Session VNS
Scheduler).
5.1 On-Demand Mode Menu
To begin on-demand stimulation therapy without a magnet:
1. Ensure that the Therapist Trigger Mode is On, from either the Program Implant menu
(see Section 4.4.2: Therapist Trigger Mode) or from the On-Demand Mode menu as
shown in Figure 5.1. This must be enabled to utilize the On-Demand Mode menu
functions. If the button adjacent to Therapist Trigger Mode is Off, toggle it to On.
Enabling Therapist Trigger Mode here automatically disables the Therapy Trigger Mode
in the Entire Session VNS Scheduler menu, and vice versa.
CAUTION: Prior to all patient MRI procedures, program the Therapist Trigger Mode to
Off. This also disables On-Demand Magnet Trigger.
