  • Neuromuscular monitoring using phonomyography
    Patent number: 7236832
    Abstract: A neuromuscular monitoring system comprises at least one neurostimulator to apply muscle-activating stimulation signals to a patient's body via at least one electrode, and at least one pressure waveform sensor to detect pressure waveform signals produced by a patient's muscle in response to the applied stimulation signals. The detected pressure waveform signals are processed and data related to these detected pressure waveform signals are displayed. A method for neuromuscular monitoring using pressure waveform sensors is also described.
    Type: Grant

  • Medical apparatus for the diagnosis of cartilage degeneration via spatial mapping of compression-induced electrical potentials
    Patent number: 5779651
    Abstract: The present invention relates to a medical apparatus for the early detection and the diagnosis of cartilage degeneration and a method for using such apparatus. The apparatus comprises at least two point electrodes, a signal processor located in proximity of the electrodes, a defined abutment in recess of the electrodes for allowing compression of the cartilage against the electrodes until the cartilage abuts against the abutment surface and a computer program for analyzing and interpreting the data received from the electrodes. The medical apparatus may be used in research to identify effects of new compounds or drugs on the cartilage or may be used in clinics to monitor the degradation of cartilage of a patient over an extended period of time.
