  • Apparatus and method for dispensing bone cement
    Patent number: 8845646
    Abstract: An apparatus and method for dispensing bone cement includes a cartridge for containing the bone cement. The apparatus also includes a plunger insertable into the cartridge. An impedance sensor is coupled to the plunger and configured to produce an output signal indicative of an impedance of bone cement contained in the cartridge. The apparatus may also include a processing circuit configured to determine an impedance value of bone cement contained within the cartridge based on the sensor signal. The processing circuit may activate a visual indicator based on the impedance value to indicate that the dough time, the end-of-work time, and/or setting-time of bone cement contained in the cartridge has been reached.
    Type: Grant

  • Method and apparatus for predicting the operating points of bone cement
    Patent number: 8574237
    Abstract: A method of predicting the operating state of a curable bone cement composition includes determining the impedance of the bone cement composition. The impedance is used to predict a number of operating states of the bone cement composition including end-of-work time and setting time.
