Fridley-based Medtronic announced it has received the FDA's blessing to market what it calls an "intelligent" insulin pump and glucose monitoring system. The new system combines a Medtronic MiniMed insulin pump with a glucose monitor from Becton Dickinson to check blood sugar, calculate the insulin needed and signal an implanted pump to send the right dose. Jeff McCaulley is Vice President and General Manager of Medtronic's Mini-Med division. He says the new device could transform the lives of the estimated four million diabetics who depend on insulin to regulate their blood sugar.
