  • Catheter with multiple microfabricated temperature sensors
    Patent number: 8475448
    Abstract: A catheter with temperature sensing has a catheter body and a tip section with integrated thermoresistive temperature sensors on its outer surface. The temperature sensor includes a microfabricated thin film assembly of which one layer is a sensor layer of thermoresistive material. In one embodiment, the tip section has a flexible tubing on whose outer surface circumferential temperature sensors are integrated. In another embodiment, the tip section has a tip electrode on whose outer surface a tip temperature sensor is integrated. In yet another embodiment, the tip section has a tip temperature sensor integrated on its tip electrode and multiple circumferential temperature sensors distal of the tip temperature sensor.

  • Method of making a cutting instrument having integrated sensors
    Patent number: 6972199
    Abstract: A cutting instrument including a metal blade has a recess formed therein and a semiconductor substrate affixed to the blade in the recess. The semiconductor substrate includes at least one sensor formed thereon. The sensor formed on the semiconductor substrate may comprise at least one or an array of a strain sensors, pressure sensors, nerve sensors, temperature sensors, density sensors, accelerometers, and gyroscopes. The cutting instrument may also further include a handle wherein the blade is affixed to the handle and the semiconductor substrate is electrically coupled to the handle. The handle may then be coupled, either physically or by wireless transmission, to a computer that is adapted to display information to a person using the cutting instrument based on signals generated by one or more of the sensors formed on the semiconductor substrate. The computer or handle may also be adapted to store data based on the signals generated by one or more of the sensors.
