1. A conformable, pliable and relatively thin transdermal drug applicator for electrophoresis or electroosmosis of at least one medicament through the skin and into the blood stream of a patient comprising:

  • (a) a plurality of juxtaposed flexible drug reservoir units formed with at least one medicament therein;

    (b) a conformable power source coupled to said plurality of juxtaposed flexible drug reservoir units, said power source having a battery and an electrical circuit formed to provide an electrical potential to said juxtaposed drug reservoir units;

    (c) a flexible, insulative and hydrophobic material surrounding said plurality of flexible drug reservoir units and said power source while leaving common sides of said plurality of flexible drug reservoir units adapted for contacting the skin, said flexible, insulative and hydrophobic material precluding shorting of said plurality of flexible reservoir units while aiding in providing flexibility to the applicator; and

    (d) a flexible cover surrounding said plurality of flexible reservoir units, said power source, and said flexible insulative and hydrophobic material while leaving common sides of said plurality of flexible reservoir units adapted for contacting the skin, said flexible cover being provided with a peripheral lip formed to releaseably cooperate with the patient'"'"'s tissue such that said flexible cover is capable of compensating for movement of the skin during transdermal drug delivery, said flexible cover in combination with said plurality of flexible reservoir units, and said flexible insulative and hydrophobic material allowing said transdermal drug applicator to conform to the surface of a patient'"'"'s tissue, the conformability of the transdermal drug applicator increasing with the number of said plurality of juxtaposed flexible reservoir units and amount of said insulative and hydrophobic material provided within the transdermal drug applicator.
