Description
Your Vesta Charger is designed to charge the battery of your
OPTIMIZER Smart Mini IPG with minimal intervention while
ensuring your safety during the charging process.
In addition, your Vesta Charger is programmed to display alerts
and other messages that may require action on your part (e.g.,
Call Doctor Alert Codes that require you to contact your doctor,
reminders to charge your implanted device, etc…).
Caution:
The operation of other electrical devices in the vicinity of
your Vesta Charger may potentially cause electromagnetic or
other interference with the charger. Portable and mobile Radio
Frequency (RF) equipment are especially prone to impair the
normal function of the charger.
Caution:
When in operation, your Vesta Charger System may be
a potential source of electromagnetic interference for other
electronic equipment in close proximity to the charger system.

Charging Method
The charging method utilized by your Vesta Charger to charge the
battery of your OPTIMIZER Smart Mini IPG is called inductive
energy transfer. Since magnetic fields can easily pass through the
skin with little to no resistance, the charging method used by your
Vesta Charger is a proven and effective way to transfer energy to
your implanted device. Charging may be performed over clothing.
The manner in which inductive energy transfer is used to charge
the battery of your OPTIMIZER Smart Mini IPG is as follows:
1. Electrical energy from the battery of your Vesta Charger
passes through a primary coil connected to the electronic
circuitry of the charger that converts it into an oscillating
electromagnetic field.
2. When a primary coil is placed in close proximity to a
secondary coil, the oscillating electromagnetic field
generated by a primary coil is picked up by a secondary
coil.
3. The secondary coil that picks up the oscillating
electromagnetic field is connected to the electronic
circuitry of the implant that converts it back into electrical
