Newly developed patch pumps are starting to occupy a noticeable fraction of the insulin delivery market. New entrants, using novel technologies, promise accurate, flexible insulin delivery at lower costs. In the section, we review the currently available devices, discuss some of the devices on the horizon, and speculate about some fascinating new approaches. In this first article, we provide an overview of the simplified devices-V-Go, PAQ, and One Touch Via-and of the more complex devices-Omnipod, Cellnovo, JewelPump, Solo, SFC Fluidics pump, Libertas, Medtronic pump, and EOPatch. We also discuss controllers, smartphones, and cybersecurity.
