Mr. Peter Crosby, President and CEO of Mainstay Medical, opens the European trading day in Paris

Mainstay Medical is an Irish medical device company that is developing an innovative implantable neurostimulation device, ReActiv8, for people with debilitating Chronic Low Back Pain.

Chronic Low Back Pain is generally defined as Low Back Pain where the pain persists for more than three months. Low Back Pain is a leading cause of activity limitation and work absence throughout much of the developed world, imposing a high economic burden on individuals, families, communities, industry, and governments. The Company estimates that in approximately 7% of all cases of Low Back Pain, the pain persists for more than three months.

ReActiv8 represents a new approach to the treatment of Chronic Low Back Pain. ReActiv8 is an implantable neurostimulation device which applies electrical stimulation to nerves that supply one of the key stabilising muscles in the back, the lumbar multifidus muscle. The hypothesis on which ReActiv8 is based is that electrical stimulation of the nerve that innervates the lumbar multifidus muscle to cause contraction of the muscle can help reactivate the muscle control system, thereby leading to improved spine stability and a reduction in the effects of CLBP.
