Relievant Medsystems, Inc., is a privately held medical device company based in Redwood City, California. Its Intracept System is a minimally invasive procedure that uses radiofrequency energy delivered into the vertebral body of the spine to ablate the basivertebral nerve. This nerve, thought to be a significant contributor in the transduction of pain associated with chronic low back pain, and its attendant disability, can no longer generate pain signals following ablation. Relievant’s primary investors include Canaan Partners, Emergent Ventures, Morgenthaler Ventures, New Enterprise Associates, and ONSET Ventures.
