Abstract
A device for the transcutaneous, in vivo measurement of the concentration of at least one analyte in a living organism includes a catheter which can be introduced into the organism, and a luminescence indicator, which is immobilized on the catheter and which reacts to a change in the concentration of the at least one analyte to be measured with a change in at least one optical property. The luminescence indicator is transcutaneously connected to a source for providing an excitation radiation and a detector for detecting the measuring radiation. The luminescence indicator is immobilized on the outer circumference of the catheter, which is used to dispense a fluid medium, for example a medication, into the organism or to drain a body fluid.
