Abstract
An implantable device which comprises two measurement chambers each of which comprises an internal measurement chamber insulated from its surroundings by a glucose-hemipermeable membrane for the first measurement chamber, and by a glucose-permeable membrane which is impermeable to molecules larger than glucose for the second measurement chamber, connected to a pressure sensor for each of the measurement chambers, and linked to an electronic system provided for informing the environment outside the organism of the value of the pressure measured in each of the two measurement chambers and, therefore, of the glucose level.
