information for Patients
• The most common surgical procedural risks are temporary pain at the implant site and infection.
However, since the leads are placed in the epidural space, there is a small risk that spinal
fluid may leak from the lead insertion site following surgery. Very rarely, you may develop an
internal blood clot (hematoma) or blister (seroma); or you may experience epidural hemorrhage
or paralysis. Your spinal cord may become compressed.
• External sources of electromagnetic disturbance may cause the device to malfunction and affect
stimulation.
• Exposure to magnetic resonance imaging (MRI) can result in discomfort or injury due to
heat near the Stimulator or the leads, tugging or vibration of the implanted system, induced
stimulation, damage to the device requiring its replacement and may distort the image needed for
diagnosis.
• Undesirable stimulation may occur over time due to cellular changes in tissue around the
electrodes, changes in electrode position, loose electrical connections and/or lead failure.
• You may experience painful electrical stimulation of your chest wall as a result of stimulation of
certain nerve roots several weeks after surgery.
• Over time, your implant may move from its original position.
