Abstract
An apparatus for the electrically assisted delivery of therapeutic agent is described. An apparatus of the invention has rigid zones or regions which are physically connected by flexible means such as a web. The flexible means permits the rigid zones 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 preferred embodiment, the skin side of the rigid zones has a radius of curvature which approximates that of the body site to which the device is to be attached.A method of increasing the body or surface conformability of a rigid electrotransport device is described. The method involves the step of intentionally placing rigid subcomponents of the device in physically separate zones within the device. The rigid zones are separate and are coupled by flexible connector means. In this manner, a conformable mosaic of rigid zones which comprises the device is created.
