Abstract
The present invention relates to a drug delivery device incorporating current and electromagnetic field sources to provide a controlled drug delivery system. The system can include a membrane with an RF antenna, a plurality of electrodes and contacts to provide an interface to a controller housing.
Claims48
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.
2 more elements
A method of delivering a preparation to a patient comprising:
- attaching a membrane to a skin surface of a patient in a region of interest, the membrane comprising an antenna for transmitting an electromagnetic field and an of electrode that transmits a current;
- connecting the antenna and electrode to a control signal source;
- activating the control signal source;
- applying the electromagnetic field to the region of interest and applying the current to a preparation;
- and
- delivering the preparation to the region of interest.
3 more elements
