The Medtronic NURO™ system delivers electrical pulses through a needle to stimulate the afferent fibers of the tibial nerve that runs posterior to the medial malleolus and extends to the sacral nerve plexus. This treatment, called Percutaneous Tibial Neuromodulation (PTNM) or Percutaneous Tibial Neurostimulation (PTNS), can restore* bladder function and quality of life for your OAB patients — without the side effects of medications† or potential self-catheterization.1,2 ‡

PTNM involves placing the needle electrode into the lower, inner aspect of either leg, slightly cephalad to the medial malleolus. A ground pad is snapped to a fitting on the underside of the NURO device, and then adhered to a clean, smooth area of skin within reach of the needle insertion site. Typical areas of application include the instep of the foot or the medical aspect of the calcaneus on the same leg as the needle insertion.
The NURO device produces an adjustable electrical pulse that travels to the sacral nerve plexus via the tibial nerve. Among other functions, the sacral nerve plexus regulates bladder and pelvic floor function.
The patient is typically treated once per week for 30 minutes for a period of 12 weeks. No decision regarding therapy effectiveness should be made until the patient completes the 12 therapy sessions. Improvement tends to increase over time throughout the 12 weeks of therapy. Finishing all 12 weeks gives your patients the best opportunity to see the results they want.3
For patients responding to treatment, the time between therapy sessions may be slowly increased after the initial 12 therapy sessions, with the patient closely monitored for the return of symptoms. If symptoms reappear or increase in severity, the patient’s treatment schedule should revert to the last previously effective treatment schedule.
Before you begin, make sure the NURO device is charged. (Device will not deliver a session without sufficient battery power.) Ensure at least one therapy session kit is available.
Restored bladder function is defined as a measurable reduction in urinary frequency and/or urinary incontinence episodes following treatment.
The most common side effects are temporary and include mild pain or skin inflammation at or near the stimulation site.
While the NURO device was not used in the Peters study cited here, since it delivers equivalent stimulation therapy as the device used in the study, a user can expect similar performance.
