Eon™ Rechargeable IPG System

This device is approved for use in the United States and select international markets.

Eon Rechargeable IPG System

The Eon Neurostimulation System offers a broad range of options to maximize the opportunity for successful pain management. Along with an extensive array of configuration, programming, and IPG placement options, this versatile system offers market-leading battery capacity and the longest time between recharges.1-4 The Eon IPG is FDA-approved to last at least 10 years at high stimulation settings, which means patients may need fewer replacement surgeries, and it is designed to provide consistent pain therapy for virtually any pain profile.

The Eon rechargeable system is compatible with an extensive array of available leads. The Eon system offers both MultiStim™ and PC-Stim™ (patient-controlled stimulation) capabilities, giving medical professionals and their patients extensive control of the stimulation therapy and a wide range of options to accommodate individual pain patterns.

  • 16-contact rechargeable IPG systems
  • Highest battery capacity
  • Safe and comfortable recharging
  • Constant electrical current delivery

Greater Implant Depth Provides Flexibility

As a result of our radiofrequency experience, St. Jude Medical is a world leader in transcutaneous energy transfer. We've used this expertise to design a system that can be implanted deeper without compromising recharge efficiency.

This provides more flexibility in device placement and minimizes the potential for tissue erosion. The Eon rechargeable IPG can be implanted up to 2.5 cm deep, improving patient comfort.

High-Capacity Battery

The Eon rechargeable IPG system features a high-capacity battery that will last at least ten years at high power stimulation outputs.1-4 If lower parameters are used, a significantly longer device life is possible.
