1. A drug delivery device comprising:
- a membrane;
an antenna mounted to the membrane that emits an electromagnetic field onto a treatment site, the electromagnetic field having a frequency and intensity that alters a condition at the treatment site;
an electrode mounted to the membrane that provides a current through the membrane; and
a circuit that connects a control signal source to the antenna and the electrode, the signal source activating emission of the electromagnetic field and the electrode current.
