Abstract
An in-vivo method and apparatus is disclosed that comprises at least one sensor for determining changes in a human'"'"'s an animal'"'"'s body and reporting said changes outside the body. The sensor may be embedded in a sheath. The apparatus may be used to monitor chemical or physical changes in the body fluids. Alternatively, the apparatus may be used to monitor and regulate chemical or physical levels in humans and animals.
