1. A system for monitoring the concentration of a chemical in a patient'"'"'s blood, body or tissues, said system comprising:
- implantable living animal cells that are sensitive to said chemical, said animal cells being capable of producing an electrical, optical, or chemical signal in response to the chemical concentration in the medium surrounding said cells in the patient; and
means for detecting said electrical, optical, or chemical signal.

Abstract
Systems are disclosed which utilize implanted chemo-sensitive living cells to monitor tissue or blood concentration levels of chemicals. The implanted cells produce a detectable electrical, optical or chemical signal in response to changes in concentration in surrounding medium. The signal is then detected and interpreted to give a reading indicative of blood concentration levels. Capsules containing chemo-sensitive cells and electrodes for detecting electrical activity are also disclosed. Methods of monitoring the concentration are also described utilizing the systems and capsules disclosed.
