  • Patent number: 4684245
    Abstract: An optical module couples a fiberoptic catheter to a catheter oximeter processing apparatus. The module includes a plurality of LED's for coupling the electrical control signals from the processor and converting them to light signals to transmit to the catheter. The module also includes the means to convert the received reflected light signals from the catheter to electrical signals to be transmitted to the processor. The module further includes a memory to store calibration signals and other data so that the module and catheter can be disconnected from the processor and used with a different processor without necessitating a recalibration.

  • Patent number: 4640279
    Abstract: A surgical instrument includes a handle and a disposable assembly which can be readily replaced after each operation or as necessary. The disposable assembly includes both an electrically heated scalpel blade and an electrosurgical active electrode which are mounted in a spaced parallel arrangement so that they can be used alternately by rotating the instrument by 180 degrees. The mounted ends of both the blade and the electrode are adapted to be received by separate terminals in the instrument handle so that the appropriate external power sources can be selectively connected thereto.
