<p>An electrotransport agent delivery device (10) having a simplified structure and ease of manufacture is provided. The device (10) utilizes an electrical circuit (40) disposed upon one of two opposing sides (43, 45) of a flexible, non-conductive substrate (42). The electrical circuit (40) comprises a source of electrical energy (46), one or more electrically conductive circuit pathways (44) and a circuit output means (48). The circuit output means (48) are connected directly or indirectly, e.g., by means of an electrically conductive adhesive (34), to the remaining components of the device such as current distribution members, lead wires, or electrodes (60, 62). In this arrangement, the circuit (40) is inverted from that of conventional electrotransport devices such that the surface (45) of the flexible substrate (42) having the electrical circuit (40) disposed thereon faces the body surface through which the drug or other agent is delivered by electrotransport. Economical, reel-to-reel methods of manufacturing a one-sided electrotransport circuit (40) are disclosed.</p> |
