Tandem Diabetes Care, Inc. is a medical device company. The Company is engaged in designing, developing and commercializing products for people with insulin-dependent diabetes. The Company manufactures and sells three insulin pump products, which include t:slim Insulin Delivery System (t:slim), t:flex Insulin Delivery System (t:flex) and t:slim G4 Insulin Delivery System (t:slim G4). Its technology platform features Micro-Delivery Technology, a miniaturized pumping mechanism, which draws insulin from a flexible bag within the pump's cartridge rather than relying on a syringe and plunger mechanism. It also features a software, which is a vivid color touch screen and a micro- universal serial bus (USB) connection that supports both a rechargeable battery and uploads to t:connect Diabetes Management Application (t:connect), its custom cloud-based data management application that provides display therapy management data from the pump and supported blood glucose meters.
