MRI Safety Guidelines
InterStim® Model 3023
InterStim II Model 3058
Non-clinical testing has demonstrated that InterStim systems have been found to be MR conditional. If a patient is implanted with an InterStim II model 3058 neurostimulator or an eligible serial number of an InterStim model 3023 neurostimulator (when implanted as a system including a neurostimulator, lead, and extension as applicable), MRI examinations of the head only may be safely performed under specific conditions.
Model 3023 serial numbers ineligible for MRI scans: Due to increased risk of neurostimulator damage, patients implanted with InterStim model 3023 neurostimulators with the following serial numbers should not have MRI scans:
- Less than NBV132955H
- Between NBV133037H and NBV133063H
- Between NBV628045S and NBV628263S
Medtronic recommends that you do not conduct an MRI examination of any part of the body on a patient using a radio-frequency (RF) transmit body coil or a receive-only head coil. Serious patient injury could result. Do not conduct an MRI examination for patients undergoing test stimulation or who have any neurostimulation system components that are not fully implanted. MRI has not been evaluated with test stimulation components. If all of the instructions stated in the MRI Guidelines for InterStim Therapy Neurostimulation Systems are followed, MRI examinations of the head only using an RF transmit/receive head coil may be safely performed.
