Once again, smartphones and tablets are becoming increasingly crucial to medical device development. This time, Johnson & Johnson's ($JNJ) LifeScan division won FDA clearance for its new OneTouch VerioSync blood glucose monitoring system. But here's the high-tech twist: J&J/LifeScan bills the product as the first glucose meter of its kind that automatically sends blood glucose data wirelessly, via Bluetooth, to an iPhone, iPad or iPod touch. This is possible, the company explains, through its OneTouch Reveal mobile app. The emergence of smartphones, tablets and apps as crucial components of medical devices comes as the FDA continues to develop guidance governing how it all will be regulated in the context of medical device use and approvals.
