Summary:In a medical lead having a sensor, an implantable device connectable to such a medical lead and a method for determining the concentration of a substance and/or molecule in blood or tissue of a patient, in particular for determining the concentration of substances and or molecules such as oxygen, carbon dioxide, molecules representative of a PH value, glucose, urea, ammonia, lactose, hormones and insulin, photoluminescent molecules embedded in a carrier, in which the substance and/or molecule to be analyzed diffuse, are excited to emit light by light emitted by a light source of the sensor. The determination of the concentration of the substance and/or molecule is based on the characteristics of the light emitted by the photoluminescent molecules.
