摘要:
A durable device is disclosed. This device allows concurrent measurement of an analyte such as glucose, and delivery of a glucose-active drug such as insulin. In order to carry out both functions, only one tubular structure is necessary. In one embodiment of the invention, wires or rings of platinum, gold, or carbon which serve as indicating electrodes are circumferentially disposed around a tubular reference electrode. In an embodiment, the reference electrode is made up of a hollow silver or silver-coated tube. The hollow characteristic is necessary in order to allow concurrent delivery of insulin or other drug through the lumen. In order to optimize sensor accuracy, there are multiple individually-addressable indicating electrodes circumferentially disposed around the shaft.
