Abstract
An electronically controlled syringe system for connection to a balloon catheter or other balloon-type member and for monitoring, displaying and recording inflation or deflation data when the syringe system is used to inflate or deflate the balloon of the catheter or other balloon-type member. A syringe having a barrel and a syringe plunger is selectively operable to increase fluid pressure applied to the balloon catheter or other balloon member by sliding the plunger further into the barrel. Positive pressure applied to the balloon catheter or member is released by withdrawing the syringe plunger towards the rear of the barrel. A piezoresistive semiconductor transducer placed in fluid communication with the fluid pressure applied by the syringe, senses the fluid pressure and outputs an electrical signal representative of that pressure. The electrical signal is received by a RF transmission module that is permanently mounted to the syringe barrel. The RF transmission module derives transmission data from the electrical pressure signal and wirelessly transmits the transmission data via a radio frequency signal to a remote console. The remote console processes the transmission data s…
