Abstract

An inflation device is disclosed for inflation of a balloon of a balloon catheter. A housing defines a fluid-receiving reservoir in fluid communication with the balloon and an interior space for completely receiving a pressure gauge which accesses the fluid for measurement of the pressure within the system. The reservoir has a piston and threaded plunger extending from a proximal opening in the reservoir. The threaded plunger is selectively engaged by a biased rotatable arm on the housing. The piston and plunger are part of a syringe received within the reservoir, and the housing defines an aperture for visual readout of the level of liquid in the reservoir. The pressure gauge contains a Bourdon tube and further contains a gauge fluid in communication with the tube. The means for isolating the inflation fluid from the gauge is an expandable bladder disposed in the neck between the gauge and the inflation fluid so that the bladder expands upon increased fluid pressure within the closed system to create a pressure readout. The housing defines an aperture for visual readout of a timer in the form of an LCD display with a frontally-illuminated screen. The timer has a manual activation lever and the housing includes an aperture allowing manual activation of the lever.
