Abstract

This invention is a system for controlling delivery of a physiological fluid internally to a patient from a balloon catheter. The system includes a controller (30), an inflation fluid pressurizer for maintaining inflation fluid in an inflation fluid conduit under pressure, and a physiological fluid pressurizer for maintaining physiological fluid in a physiological fluid under pressure. The inflation fluid pressurizer is connected to receive signals from the controller to cycle pressure in the inflation fluid conduit between a balloon inflating pressure and a balloon deflating pressure. The physiological fluid pressurizer is connected to receive signals from the controller to cycle pressure in the physiological fluid conduit between a fluid delivery pressure and a resting pressure. The controller (30) is programmed to synchronize signals to the inflation fluid pressurizer with signals to the physiological fluid pressurizer. Thus periods of balloon inflating pressure in the inflation fluid conduit generally overlap with periods of fluid delivery pressure in the physiological fluid conduit, and periods of balloon deflating pressure in the inflation fluid conduit generally overlap with periods of resting pressure in the physiological fluid conduit.
