  • Publication number: 20230023897
    Abstract: A system that provides the ability to integrate both diagnostic tissue detection and therapeutic tissue treatment functionality in an implantable medical device (IMD), such as a graft or stent. The system comprises: an IMD having a pair of electrodes configured to contact biological tissue at an implant location; an impedance sensor configured to detect data indicative of a complex impedance of the biological tissue at the electrodes for a plurality of frequencies; and an analysis device configured to determine one or more cell types in the biological tissue using information indicative of variation in phase and magnitude of the complex impedance across the plurality of frequencies. The system may include a signal generator for applying a treatment signal to the same electrodes.

  • Patent number: 10624547
    Abstract: Devices and systems described herein relate to a sensing device that includes an output area and an electrode area. The output area includes an output circuit comprising an integrator adapted to integrate a received current so as to generate an output voltage corresponding to the received current. The electrode area includes an electrode comprising an exposed, electrically conductive, surface area and electrode circuitry connected to the exposed surface area. The electrode circuitry comprises a voltage-to-current transducer adapted to produce a wire current corresponding to a voltage present at the exposed surface area. The sensing device also includes a connecting wire electrically connecting the electrode circuitry to the output circuit, wherein the current received by the output circuit is the wire current.

  • Patent number: 10376175
    Abstract: The disclosure relates to a sensor, a system, and a holder arrangement for biosignal activity measurement. One example embodiment includes a sensor module for brain activity measurement. The sensor module includes a main electrode base. The sensor module also includes a plurality of pins protruding from the main electrode base. The plurality of pins is arranged such that, when applied on a subject, the pins make contact with skin of the subject or are in close proximity with the skin of the subject. The main electrode base comprises electronic circuitry for near infrared spectroscopy (NIRS) measurements and electronic circuitry for electroencephalography (EEG) measurements, both connected to the plurality of pins. The plurality of pins includes electrically conductive pins. The plurality of pins also includes at least one source waveguide pin configured for light emitting purposes or at least one detector waveguide pin configured for light detection purposes.

  • Patent number: 10044325
    Abstract: An amplifier circuit, a voltage sensing apparatus, and an amplification method are disclosed. The amplifier circuit comprises (1) an input stage comprising a first set of transistors to which an input signal to be amplified is applied, the transistors of the first set comprising a semiconductor body, and (2) a processing stage comprising a second set of transistors for processing the signal from the input stage and generating an output signal. The transistors of the first set have a thicker gate oxide than the transistors of the second set, and are therefore suitable for higher voltage operation. The first and second sets of transistors are supplied by the same voltage supply of the amplifier circuit. The semiconductor body of the first set of transistors is connected to a reference potential to lower the threshold voltage.
