Xavant Technology, a company based in Pretoria, South Africa, won FDA clearance for its NMS 460 peripheral nerve stimulation system. The device is used to address chronic intractable pain, post-surgical pain, post-traumatic acute pain, and for pain control arising from rehab routines.
The device delivers a hybrid pulsed radio frequency (PRF) waveform, developed by Xavant, through the skin via an accompanying stylus. The company claims that the resulting electromagnetic effects are similar to the ones that implanted neurostimulators generate, delivering some of the benefits of such devices without their invasive nature.
The device also has a nerve mapping probe that helps to spot damaged nerves, and to assess their state and how they’re responding to treatment.
