St. Jude to test chronic pain control without the tingling

article by: JAMES WALSH , Star Tribune, December 4, 2013

For people with chronic pain, the growth of neurostimulation — use of an electric current to block pain messages from reaching the brain — has been a welcome relief. But the technology loses its effectiveness over time and comes with a pesky tingling sensation.

St. Jude Medical Inc. is hoping to end those problems with its Prodigy neurostimulator. The Little Canada-based company said Tuesday it is beginning to enroll U.S. patients in a clinical study of its new spinal cord stimulation system, which delivers what it calls burst stimulation. Burst stimulation delivers closely spaced pulses of electrical energy to a patient’s spinal cord, followed by stretches of quiet — no pulses at all.

The technology “represents an important advancement in neurostimulation therapy,” said Dr. Mark D. Carlson, chief medical officer and vice president of global clinical affairs for St. Jude. “We are excited to be leading the effort ... to bring this novel stimulation mode to market.”
