QoS for Communications between the Vesta Charger and the OPTIMIZER
Smart Mini IPG
MedRadio in the MICS sub-band (402 to 405 MHz) wireless technology enables
communication between the OPTIMIZER Smart Mini IPG and the Vesta Charger.
The requirements for the Quality of Service (QoS) vary depending on the use
environment (operating room, recovery room, clinic, and home environment).
The Vesta Charger will begin by displaying the IPG Data Download and IPG
Data Download Success screens:
After the data download has been completed, the Charging IPG Status screen is
displayed by the Vesta Charger:
The Charging IPG Status screen’s Coupling Level icon ( ), whose number of
illuminated bars is proportional to the proximity of the charging wand to the
implanted OPTIMIZER Smart Mini IPG, is indicative of the Quality of Service
(QoS) for the transcutaneous energy transmission wireless link. The charging
wand should be repositioned until at least 2 bars of the Charging IPG Status
screen’s Coupling Level icon are illuminated, indicating sufficient QoS for
charging the OPTIMIZER Smart Mini IPG.
One illuminated bar indicates degraded QoS which may require a longer
charging time. Zero illuminated bars on the Charging IPG Status screen’s
Coupling Level icon accompanied by an audible beeping tone indicates poor
placement of the charging wand. If the charging wand is not repositioned onto
the implant site within 20 seconds, the Vesta Charger will emit 3 long beeping
tones, display the Charging IPG Coupling Error screen, and then shut off.
Besides charging the OPTIMIZER Smart Mini, the Vesta Charger also serves as
a way of messaging the patient about alerts and other conditions. The Vesta
Charger is configured to communicate with the OPTIMIZER Smart Mini IPG at
least once a day. This communication occurs whenever the IPG is at least 1.5 m
(5 ft) of the Vesta Charger for a few minutes.
