  • Medical device equipped with sensors
    Patent number: 11172885
    Abstract: 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.

  • Method for determining at least one type and/or condition of cells and system
    Patent number: 10912482
    Abstract: The invention relates to a method for discriminating cells of a cellular structure, notably of a cellular tissue, comprising the steps consisting in determining (12) a frequency spectrum of the impedance of the cellular structure; defining (22) at least one model of the impedance of the cellular structure including a constant phase element (30); determining (44) the impedance of the constant phase element (30) which optimizes the correlation of each model of the impedance of the cellular structure with the spectrum; and deducing (66), from the impedance of the constant phase element (30) or from the impedances of the constant phase elements (30), 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.

  • Method for producing insulated electrodes for applying electric fields into conductive material
    Patent number: 8705223
    Abstract: The present disclosure relates to a method for producing an insulated electrode comprising a conductive material coated with an electrically insulating material. The method includes at least the following steps of: forming a mold in an electrically insulating material, the mold including at least one channel, the mold being adapted to confine a conductive material, introducing the conductive material in a liquid state into the channel of the mold, the conductive material having a melting point that is lower than the melting point of the electrically insulating material.
