Electrotransport system with remote telemetry link
First Claim
1. In an electrotransport system for delivering a therapeutic agent through a body surface of a patient, the system including a delivery unit having a pair of electrodes, at least one of the electrodes containing the therapeutic agent to be delivered, a source of electrical power electrically connectable to the electrodes, and a control unit for communicating with the delivery unit, the improvement comprising:
- the delivery unit being physically remote from the control unit; and
a telemetry communication link between the delivery and control units whereby the units communicate through a radiated energy signal transmitter and a receiver.

Abstract
An electrotransport system (20) for delivering a therapeutic agent (36) through a body surface (40) (eg, skin) of a patient includes a pair of electrodes (34, 38) for contacting the body surface, at least one of which contains the therapeutic agent (36). The system (20) is physically separated into a control unit (22) and a delivery unit (24) connected by a radiated energy signal-based telemetry link. The telemetry link may be radio frequency, ultrasonic, optical, infrared or inductively coupled. Signals from the control unit may be transmitted to the delivery unit by the telemetry link, or vice versa. The delivery unit may control electrotransport current on the signal transmitted. The radiated energy signal may be encoded to improve immunity to extrinsic interference. The delivery unit (24) may be configured with sensor means for detecting a condition such as a body or system parameter reaching some predetermined limit. The delivery unit (24) may also have an additional telemetry link connecting to the control unit (22) for transmitting the system or body status condition to the control unit. Visual or audio indicators may be provided on the control unit (22) for indication of system or body status conditions detected and transmitted by the delivery unit (24).
