Abstract: A unique syringe useful in the inflation and rapid deflation of a balloon used in balloon catheterization (transluminal angioplasty) procedures is disclosed. The syringe has a uniquely actuated thread engaging block which is engaged and disengaged by a rotary cam member interacting with the thread-engaging block. The thread engaging block engages a threaded piston rod which is attached to the piston within the barrel of a balloon catheter syringe. A rotary cam member engages the block so as to exert a positive force on the block, either moving the block into a thread engaging position or moving into a thread disengaging position. The unique syringe may also contain a piston face which is segmented so that a portion of the piston face is separately actuatable in order to introduce a minor increase in pressure while the main piston member remains in a stationary position.

Abstract: Apparatus for remotely displaying the inflation pressure within an inflator for inflating a balloon catheter. The apparatus comprises a pressure transducer positioned to sense pressure within the syringe, a transmission unit receiving a pressure signal from the transducer and transmitting by means of infrared light pulse sequences, a pressure message reflective of the pressure signal. A monitor positionable at a distance from the transmission unit receives and decodes the pressure messages, and provides a display thereof. A timer key for initiating the transmission of start/stop clock messages is located on the inflator unit. The monitor further includes a timer responsive to received clock messages, and an elapsed time display.
