Tandem Diabetes Care out of San Diego, CA will soon be marketing in the U.S. its t:slim insulin pump thanks to a newly issued FDA approval. 
The t:slim looks more like an iPhone 4 than a critical medical device, including a color touchscreen and USB connectivity for syncing with a computer and for recharging the internal battery.
This may not be a coincidence because the rep for Tandem, in an email to Medgadget, specifically mentioned Amy Tenderich’s open letter to Steve Jobs calling for Apple to design an insulin pump from four years ago. We think Amy should take at least a bit of credit for encouraging such a stunning design.
The slide-out insulin cartridge is easy to change and the device can connect to PC’s and Macs to upload pump data to a web-based application for further review.
