<p>An apparatus for supplying power to deliver a beneficial agent or drug through a body surface of a patient is provided. In a first embodiment, the invention includes a power supply (e.g., a battery 118, 119) and optionally other electrical components (126, 128), positioned in a pocket (114) formed in a supporting substrate (112). Electrically conducting traces (113, 116) positioned on the substrate (112, 113) form an electrical power network connecting the battery (118, 119) to the other electrical components (126, 128), for control and delivery of electrical power. The traces may be electrically conducting adhesive strips (206). In a second embodiment, a waterproof enclosure provides moisture isolation of electrical components in an electrical power network. The waterproof enclosure may be selectively formed around one or a group of electrical components (202, 204, 218) by sealing a sealant film (208, 210). External outputs (207, 209) are provided to make electrical contact with closely adjacent electrodes (D, C) at least one of which holds a liquid containing a therapeutic agent.</p> |
