Abstract
A system for controlling delivery of a physiological fluid internally to a patient from a balloon catheter. The system includes a controller, 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 conduit 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 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.
