1. A method for performing a percutaneous catheter-based heart valve repair or replacement in a patient comprising the steps of:
- connecting the patient'"'"'s vasculature to a heart-lung machine which has a controller and a blood flow and treatment circuit, said blood flow and treatment circuit comprising a venous blood inflow conduit, a blood reservoir, an oxygenator, a blood pump, a bubble detector, a filter, and an arterial blood outflow conduit, said controller being programmed to control an automatic priming and air removal process whereby the blood flow and treatment circuit is automatically filled with a priming liquid and air is vented, without the presence of a trained perfusionist or cardio-technician;
connecting the blood flow and treatment circuit to a source of priming fluid;
causing the controller to perform the automatic priming and air removal process whereby the venous blood inflow conduit, blood reservoir, oxygenator, blood pump, bubble detector, filter, and arterial blood outflow conduit become primed with fluid and substantially free of air, without the presence of a trained perfusionist or cardio-technician;
after completion of the automatic priming and air removal process, operating the heart-lung machine to circulate oxygenated blood through the patient'"'"'s vasculature;
percutaneously inserting a heart valve repair or replacement catheter and advancing the heart valve repair or replacement catheter to the location at which the heart valve is to be repaired or replaced; and
using the heart valve repair or replacement catheter to repair or replace the heart valve;
wherein the heart-lung machine is alternately operable using either a battery power supply or by connection to an external electrical power supply; and
wherein the method further comprises the step of operating the heart-lung machine during all or part of the method using a power supply selected from a) a battery power supply and b) an external electrical power supply.
