DexCom Inc., a San Diego-based medical device company, announced that it has received U.S. Food and Drug Administration approval for a continuous glucose-monitoring system with data-sharing capabilities.

The Dexcom G4 Platinum Continuous Glucose Monitoring System with Share uses a secure wireless connection via Bluetooth Low Energy between a patient’s receiver and an app on the patient’s smartphone to transmit glucose information to apps on the mobile devices of up to five designated recipients, or “followers,” without the need for a dedicated docking cradle.

These followers, such as doctors and caregivers, can remotely monitor a patient’s glucose information and receive alert notifications from almost anywhere, initially via their Apple iPhone or iPod Touch and in the future on Android devices. The “Share” and “Follower” apps will be available on the Apple App Store at no charge.
