摘要：
An implantable medical device includes a hermetically sealed housing and a first light emitting diode (LED) enclosed within the housing configured to detect light corresponding to a selected light wavelength. A conductive element extends from the LED for carrying a current signal corresponding to the light detected by the LED, the intensity of the detected light being correlated to a change in a physiological condition in a body fluid volume or a tissue volume proximate the LED.
