Patent ID: 7945320

Claim:
An iontophoretic drug delivery system for driving charged drug molecules into a tissue, comprising: a flexible body configured to conform to a portion of a patient's body that includes the tissue, the flexible body including a top surface, a bottom surface, and at least one through hole; a drug reservoir holding the charged drug molecules; an iontophoretic electrode configured to iontophoretically deliver the charged drug molecules from the drug reservoir into the tissue, the electrode being formed of an electroconductive material printed on the bottom surface of the flexible body, wherein the drug reservoir is located adjacent to the iontophoretic electrode such that the iontophoretic electrode is between the drug reservoir and the flexible body; a microprocessor controller configured to control iontophoretic delivery of the charged drug molecules from the drug reservoir into the tissue by the iontophoretic electrode, the microprocessor located adjacent to the top surface of the flexible body; circuitry that couples the microprocessor to the iontophoretic electrode, the circuitry being formed of flexible electroconductive material printed on the top surface of the flexible body; an electroconductive material in the at least one through hole that couples the circuitry to the iontophoretic electrode, wherein the electroconductive material fills the through hole such that moisture is prevented from passing from the bottom surface to the top surface via the through hole when at least a portion of the bottom surface is located adjacent to the tissue; an antenna coupled to the microprocessor controller, whereby the microprocessor controller is programmed by signals sent through the antenna; and a battery coupled to the microprocessor controller located adjacent to the top surface of the flexible body.
