A device (10) for the electrically assisted delivery of a therapeutic agent is described. The device (10) has rigid zones or regions (12, 14) which are physically connected by a flexible means (16) such as a web. The flexible means (16) permits the rigid zones (12, 14) to move independently with respect to each other while remaining physically connected or coupled. In a preferred embodiment, the rigid zones are physically and electronically coupled by the flexible means. In another embodiment, the device (500) comprises one or more rigid zones, the skin side of the rigid zone having a radius of curvature (520) which approximates that of the body site to which the device (500) is to be attached. A method of increasing the body surface conformability of an electrotransport device (50, 150, 170) is described. The method involves the step of intentionally placing rigid subcomponents (58, 36, 37) of the device in physically separate zones (52, 54; 152, 154, 156, 158; 172, 174, 176, 178) within the device. The rigid zones (52, 54; 152, 154, 156, 158; 172, 174, 176, 178) are separate and are coupled by flexible connector means (56, 62; 160, 162). In this manner, a conformable mosaic of rigid zones which comprises the device is created.

[ We claim:] [1.] A device for delivering an agent by electrotransport through a body surface, the device having a source of electrical power electrically connected to a pair of electrode assemblies, one of the pair of electrode assemblies having a reservoir for containing the agent to be delivered, the device comprising at least two regions which are placed against the body surface at spaced apart locations and which are held in intimate contact with said body surface, at least one of the two regions being rigid and comprising the power source and an electrode assembly, the regions being physically connected to one another by a connector, the connector having a folded non-extended configuration and an unfolded extended configuration, whereby the regions may be placed on the body surface at: (i) a first set of locations when the connector is in the folded non-extended configuration, or (ii) a second set of locations less proximate that the first set of locations when the connector is in the extended unfolded configuration.
