Fluid management system for coronary intervention

A method of injecting fluid into a patient, comprising:

• providing a first power-actuated injector adapted to transport a first fluid from a first receptacle through a first fluid line;
• providing a second power actuated injector adapted to transport a second fluid from a second receptacle through a second fluid line;
• connecting the first and second fluid lines to a single catheter;
• providing a pump adapted to transport fluid from the catheter, first fluid line, and second fluid line to a waste receptacle actuating one of the first and second power-actuated injectors;
• and
• monitoring pressure using a transducer mounted proximate the catheter.

An injection system, comprising:

• a first power-actuated injector;
• a second power-actuated injector;
• a catheter;
• a fitting having an output and first and second inputs, the output being connected to the catheter;
• the first and second inputs being connected to the first and second injectors;
• a waste line and a pump operatively associated with the waste line, the waste line having an input in fluid communication with the fitting
• a pressure transducer positioned proximate the catheter and adapted to generate a signal representative of fluid pressure within the catheter;
• and
• a controller adapted to receive signals and generate control signals for actuation of the first and second power actuated injectors.

An injection system, comprising:

• an injector;
• a medical device;
• a fluid line connecting the medical device and the injector;
• a waste line and a pump operatively associated with the waste line, the waste line being connected to the fluid line;
• a pressure sensor connected to the fluid line downstream of the waste line and adapted to generate a signal representative of fluid pressure within the medical device;
• and
• a controller adapted to receive a signal and generate a control signal for controlling the flow of fluid from the injector.

An injection system, comprising:

• a power-actuated injector;
• a medical device;
• a fluid line connecting the medical device and the injector;
• a waste line connected to the fluid line;
• a pressure sensor connected to the fluid line downstream of the waste line and adapted to generate a signal representative of fluid pressure within the medical device;
• a pump operatively associated with the waste line and adapted to draw fluid from the medical device fluid line and injector;
• a second power actuated injector and a second fluid line, the second fluid line connecting the second power actuated injector to the medical device;
• and a third fluid line connected to a medication.
