How the St. Jude Medical™ Invisible Trial System Works
A temporary neurostimulation system allows you and your doctor to determine the effectiveness of neurostimulation for your pain before undergoing a permanent implant. You will be fitted with a temporary or trial device, including an external pulse generator (EPG) that works like an implanted system but can be easily removed.
The St. Jude Medical Invisible Trial System consists of three components:
Thin wires that deliver stimulation from an external generator to nerves along the spinal cord.
A small device that sends pulses to the lead.
A handheld device that lets you adjust your therapy wirelessly. The patient controller for the St. Jude Medical Invisible Trial System is an Apple‡ iPod touch‡ mobile digital device.
