NeuroMetrix Inc. announced that it received a 510(k) clearance (K152954) from the U.S. Food and Drug Administration (FDA) for an upgraded version of Quell, the company's over-the-counter, 100% drug free chronic pain relief wearable. Under this 510(k), the Quell device can be controlled directly via the Quell Relief smartphone app. This provides an unprecedented level of convenience and comfort when using Quell to treat chronic pain.

Quell is designed for people with a wide range of chronic pain conditions. The latest version of Quell gives users the option to control their therapy via a mobile app and includes several additional enhancements including extended battery life and advanced sleep tracking. It will be available in March 2016.

NeuroMetrix will have a free upgrade program for existing Quell users who send in their previous generation devices when the new version is available in March.
