Magnetic Resonance Imaging (MRI)

The Enterra® Therapy System is MR Unsafe — Patients with an implanted Enterra or Enterra II Therapy System should not be exposed to the electromagnetic fields produced by Magnetic Resonance Imaging (MRI). The interaction of the MRI with the neurostimulation system may lead to serious injury or death. Use of MRI may also result in system failure, dislodgement, heating, or induced voltages in the neurostimulator and/or lead. An induced voltage through the neurostimulator or lead may cause uncomfortable, “jolting,” or “shocking” levels of stimulation.
