St. Jude Medical, a global medical device company, has announced the approval of its Protégé IPG from the US Food and Drug Administration (FDA).

Protégé is the first and only neurostimulation system that allows spinal cord stimulation (SCS) technology upgrades as they are approved to be made via software updates.

Chronic pain sufferers implanted with this new device can access innovative therapies, stimulation modes, diagnostics or other features once approved through future software upgrades — without the need to surgically replace their medical device.

Until now, one of the greatest challenges with neurostimulation has been giving patients access to the latest technologies without surgically replacing their medical device. Protégé changes the standard for SCS, allowing patients to access future innovations and therapies once approved without the cost and risks associated with surgical replacement.

Protégé is the world’s smallest neurostimulator to treat chronic pain of the trunk or limbs and pain from failed back surgery. It has an unmatched seven-year warranty and offers industry-leading ten-year projected battery life. It also has open-ended device longevity without an automatic shutoff.

Protégé is built on a solid platform of success: 88% percent of patients report satisfaction at two years post-implant with a St. Jude Medical neurostimulator, saying their quality of life has been greatly improved.

Similar in function and appearance to a cardiac pacemaker, the Protégé neurostimulator delivers mild electrical pulses to the spinal cord, which interrupt or mask the pain signals’ transmission to the brain.

St. Jude Medical group president Dr Eric S Fain noted that spinal cord stimulation therapy can transform the quality of life for patients who are otherwise unable to find relief from their chronic pain.

"Protégé allows patients the opportunity to benefit from future therapies and features even after they receive their implanted system. This draws upon St. Jude Medical’s promise to the quality and durability of its products and our commitment to continuously innovating in the neuromodulation space," Dr Fain added.

The Protégé neurostimulator and Prodigy Chronic Pain System with Burst Technology, which recently earned European approval, represent St. Jude Medical’s devotion to advancing new therapies in neuromodulation and providing options for chronic pain sufferers.

Additionally, two clinical trials sponsored by St. Jude Medical that started in December 2013 are investigating alternative stimulation methods in spinal cord stimulation.

Through an Investigational Device Exemption (IDE) from the FDA, St. Jude Medical is evaluating whether a new waveform called burst stimulation can be more effective in managing chronic pain than traditional tonic stimulation.

The purpose of the study, dubbed SUNBURST (Success Using Neuromodulation with BURST), is to evaluate the safety and efficacy of the Prodigy neurostimulator for the treatment of chronic intractable pain of the trunk and/or limbs. Prodigy is not approved for use in the U.S.

The SENSE Subcutaneous and Epidural Neuromodulation System Evaluation study is designed to evaluate the combination of peripheral nerve field stimulation (PNfS) and SCS to determine whether the two therapies together offer more effective management of chronic low back and leg pain than SCS alone.
