    • The present invention provides a sensor head for use in an implantable device that measures the concentration of an analyte in a biological fluid which includes: a non-conductive body; a working electrode, a reference electrode and a counter electrode, wherein the electrodes pass through the non-conductive body forming an electrochemically reactive surface at one location on the body and forming an electronic connection at another location on the body, further wherein the electrochemically reactive surface of the counter electrode is greater than the surface area of the working electrode; and a multi-region membrane affixed to the nonconductive body and covering the working electrode, reference electrode and counter electrode. In addition, the present invention provides an implantable device including at least one of the sensor heads of the invention and methods of monitoring glucose levels in a host utilizing the implantable device of the invention.
    • 本发明提供了一种用于可植入装置的传感器头,其用于测量生物流体中分析物的浓度,其包括:非导电体; 工作电极,参考电极和对电极,其中电极穿过非导电体,其在身体的一个位置处形成电化学反应性表面,并在身体的另一位置形成电子连接,其中电化学反应性 对电极的表面大于工作电极的表面积; 以及附着在非导体上并覆盖工作电极,参比电极和对电极的多区域膜。 此外,本发明提供一种可植入装置,其包括本发明的至少一个传感器头和利用本发明的可植入装置监测主机中的葡萄糖水平的方法。
