A medical device including an electric measurement circuit, in which are connected at least two sensors the impedance of which varies as a function of a sensed physical parameter, a source of electrical power for powering the electric measurement circuit, an antenna for emitting an electromagnetic field as a function of the impedance of the electric measurement circuit, each of the sensors being associated with a switch for short circuiting the sensor in the measurement circuit, the medical device further including a system for controlling the switches in order successively to command the opening or closing of the switches in determined configurations. The medical device may notably be able to be applied to the human body or implanted in the human body.

Medical device equipped with sensors

The invention relates to a method for discriminating cells of a cellular structure, notably of a cellular tissue, comprising the steps consisting in determining () a frequency spectrum of the impedance of the cellular structure; defining () at least one model of the impedance of the cellular structure including a constant phase element (); determining () the impedance of the constant phase element () which optimizes the correlation of each model of the impedance of the cellular structure with the spectrum; and deducing (), from the impedance of the constant phase element () or from the impedances of the constant phase elements (), an item of information on the cells of the cellular structure. The invention also relates to a system for implementing the method for discriminating cells of a cellular structure.
