Abstract

Systems and methods to determine presence of an analyte using an implantable medical device are disclosed. In an embodiment, a medical system includes an implantable medical device, a light source, an optical sensor and a processor. The implantable medical device includes an indicator tag, which is responsive to an analyte. The light source is configured to emit light onto the indicator tag, where the emitted light comprises at least one wavelength of light, and where the indicator tag emanates light, in response to the emitted light, that corresponds to whether the indicator tag is exposed the analyte. The optical sensor is configured to receive at least a portion of the emanated light, which includes at least one wavelength of light. And, the processor is configured to determine whether the indicator tag is exposed to the analyte based on the received light.
