Mainstay Medical Holdings plc has won U.S. FDA approval for its Reactiv8 implantable neurostimulation device. The company is eyeing a commercial launch of the system in early 2021. The FDA approved Reactiv8 as an aid in managing intractable chronic low back pain associated with multifidus muscle dysfunction in adults who have failed therapy and are not candidates for spine surgery.

The U.S. FDA granted Gtx Medical BV a breakthrough device designation for its implantable Go-2 Targeted Epidural Spinal Stimulation (TESS) system. The device enabled patients who had sustained traumatic spinal cord injuries to regain voluntary control over previously paralyzed muscles and walk again four or more years after paralysis, according to a study previously published in Nature.

Researchers at New York-based Feinstein Institutes for Medical Research, the research arm of Northwell Health, showed that anodal block can be used for directional vagus nerve stimulation (VNS) in a new paper in Scientific Reports.
