Electrochemical sensor for the determination of an analyte concentration
First Claim
1. An electrochemical sensor for the determination of a concentration of at least one analyte in a body tissue or a body fluid, the electrochemical sensor having an isolation element and at least two electrodes, the at least two electrodes extending from an insertion end for insertion in the body tissue to an opposite second end, the at least two electrodes comprising a working electrode and at least one of a counter electrode and a reference electrode, wherein the at least two electrodes are at least partially formed as wire-shaped electrodes, the isolation element comprising a profiled shape and at least two holding compartments for the at least two electrodes, wherein the at least two electrodes extend along the isolation element in respective ones of the at least two holding compartments, and run substantially parallel to one another and have peripheral electrode surfaces along the at least two holding compartments that extend substantially from the insertion end to the opposite second end.

Abstract
The invention relates to an electrochemical sensor for the determination of a concentration of at least one analyte in a medium, in particular a body tissue and/or a body fluid, to an apparatus that includes the electrochemical sensor, and to a use of the electrochemical sensor, and finally to a method for producing it. The electrochemical sensor has an isolation element and at least two electrodes. The at least two electrodes comprise at least one working electrode and at least one further electrode, in particular at least one counter electrode and/or at least one reference electrode. The at least two electrodes run parallel to one another and form an electrochemical measuring cell of the electrochemical sensor.
