Protege IPG Clinician’s Manual

 Product Description

The Protege™ IPG is a rechargeable, electronic device designed to be connected 
to one or more extensions or leads with up to 16 electrodes total. It is powered 
by a hermetically sealed battery within a titanium case and uses microelectronic 
circuitry to generate constant-current electrical stimulation. The IPG can deliver 
stimulation with a single program or with multiple programs (called MultiStim™ 
programs). New features can be introduced to the Protege system via software 
updates allowing for upgraded technology to be used. A St. Jude Medical external 
programmer may be needed for certain types of software updates to this product.

NOTE:

 For more information about the neurostimulation system, see the clinician’s programming 

and reference manual for this system.
