DRG Stimulation Therapy

Chronic Pain Relief with DRG Stimulation Therapy

St. Jude Medical, Inc., a global medical device company, is partnering with Coastal Spine and Pain Center to launch the St. Jude Medical AxiumTM Neurostimulator System for dorsal root ganglion (DRG) stimulation to treat patients with chronic pain that has been hard to control with traditional spinal cord stimulation (SCS).


  • For patients with Complex Regional Pain Syndrome (CRPS)
  • For patients who are underserved by traditional Spinal Cord Stimulation (SCS), many patients are symptom-free after DRG procedure

What is Chronic Pain?

Chronic pain is a largely under-treated and misunderstood disease that affects millions of people world- wide. It is de ned as moderate to severe pain that persists for one or more months longer than would generally be expected for recovery to a specific disease, injury or surgery. According to the National Institutes of Health, 90 million people in the U.S. su er from chronic pain. The American Pain Foundation estimates that chronic pain costs approximately $100 billion per year in lost work time and health care expenses.

What is CRPS?

Complex Regional Pain Syndrome (CRPS) is a chronic pain condition that affects a part of the body following an injury or trauma. CRPS is felt to be caused in part by damaged or malfunctioning nerves. CRPS affects the way the central nervous system and the peripheral nervous system send pain signals from the brain and spinal cord to the rest of the body. Often characterized by prolonged or excessive pain, CRPS can cause mild or dramatic changes in skin color, temperature, and/or swelling in the affected area.

What is the St. Jude Medical AxiumTM Neurostimulator System?

The AxiumTM Neurostimulator System is the first and only neurostimulation device designed for dorsal root ganglion (DRG) stimulation. By stimulating the DRG, a spinal structure densely populated with sensory nerves that transmit information to the brain via the spinal cord, the St. Jude Medical Axium system delivers a form of spinal stimulation that gives physicians the ability to treat the specific areas of the body where pain occurs. For patients with neuropathic chronic intractable pain associated with CRPS – conditions underserved by traditional SCS – stimulation of the DRG can provide pain relief when previous treatment options have not provided adequate pain relief.
