Patent ID: 7981078

Claim:
An inflation/deflation system for a dilatation balloon, said system comprising: a) a receptacle adapted to contain an inflation fluid to be introduced into said balloon during its inflation, said receptacle having an inlet/outlet port adapted for connection to said dilatation balloon; b) a pressure member adapted to be axially displaced within said receptacle to cause said fluid to exit the receptacle via said outlet port; c) a sensing system comprising a first sensor associated with said pressure member to sense its axial displacement, a second sensor associated with the interior of said receptacle to sense in a non-contact manner the pressure P of the inflation fluid within said receptacle, and an additional sensor associated with the pressure member to sense the pressure on the pressure member during said axial displacement for comparing it with the pressure of the inflation fluid within the receptacle; and d) a data processing and display unit adapted to process signals from the sensors and display at least a scheme of pressure P within said receptacle vs. the volume V of the inflation fluid exiting said receptacle through said inlet/outlet port, calculated by said axial displacement, said scheme reflecting the corresponding P-V conditions within the balloon when the system is in use.
