Abstract
In various embodiments, a drug-delivery device includes a skin patch with an integral delivery vehicle adherable to a patient'"'"'s skin. An exterior surface of the patch defines an envelope within which is disposed a programmable drug pump including a reservoir, a cannula for conducting liquid from the reservoir to the delivery vehicle, and a mechanism for forcing liquid from the reservoir through the cannula and into the delivery vehicle.
