NeuroMetrix says wearble technology for treatment of chronic pain cleared by FDA NeuroMetrix announced that its wearable technology for treatment of chronic pain received 510(k) clearance from the U.S. Food and Drug Administration for over-the-counter use. The company is in late stage development of a consumer oriented chronic pain treatment product. The device is based on wearable technology, presently deployed in the company’s SENSUS Pain Management System, that utilizes comfortable, non-invasive electrical stimulation of sensory nerves to induce safe and effective pain relief. It is lightweight and can be worn during the day while active, and at night while sleeping. This 510(k) clearance allows the company to market the over-the-counter device through retail distribution channels without a prescription requirement.
