Patent ID: 8000763

Claim:
An integrated medication delivery device and electrode structure, comprising: an electrode structure comprising a first conductive material, a second conductive material, and a dielectric material, wherein the first conductive material, the second conductive material, and the dielectric material are coextruded to provide an electrode structure having the first conductive material and the second conductive material electrically isolated by the dielectric material, wherein the first conductive material comprises a working electrode and the second conductive material comprises a reference/counter electrode, the working electrode comprising an analyte responsive enzyme disposed on, in or proximate thereto, wherein the electrode structure comprises a lumen, the lumen comprising a first opening, a second opening, and a lumen wall, wherein the dielectric material defines the lumen wall, and wherein the electrode structure includes a plurality of stand-offs along the lumen wall and extending inward into the lumen; and a medication delivery device coupled to the lumen and configured to deliver a medication through the lumen to the subject.
