<p>It is not uncommon for patients to be subjected to multiple blood tests in order to monitor a particular medical condition. An implantable sensor (2) is disclosed for use with an external transmitter/receiver (8) to monitor the value of a parameter within a living mammal. The sensor comprises a light source (12) and an indicator system (26) which is responsive on exposure to said light source to the level of said parameter in a body fluid within said mammal. Detector means (16, 18) detects the response of the indicator means to the value of said parameter. The light source and detector are contained by a capsule (22, 24) which is impermeable to body fluid, but having at least a window allowing transmission of light to and from the tissue or indicator system.</p> |
