ABSTRACT:
A motor controller for providing a constant rate of change of pressure during inflation and deflation of an expandable member of a catheter for use in a body lumen by an automated inflation system is disclosed. The system conforms the rate of change of pressure to a set point value by means of a feedback loop controller, and makes possible consistent inflations and deflations using an automated system regardless of variations in catheter volume and compliance characteristics. Safety features such as maximum pressure and balloon rupture alarms are also disclosed.
