Becton Dickinson & Co. (BD) is developing a wearable insulin patch pump, which would help the Franklin Lakes, N.J.-based company expand its $1 billion diabetes care division. The device would take BD's current diabetes offerings beyond insulin syringes, pen needles and lancets. Last week, the company revealed the product during analyst day. BD said it hopes to launch its insulin patch pump for patients with type 2 diabetes in its 2018 fiscal year.
