  • Devices, systems and methods for delivery of a fluid into a patient during a magnetic resonance procedure
    Patent number: 7632245
    Abstract: A device for injection of a fluid into a patient includes a container adapted to hold the fluid and defining an outlet through which the fluid can exit the container. A pressurizing mechanism is in connection with the container for pressurizing the fluid, and an actuator is in fluid connection with the outlet. The actuator has a first state in which fluid is prevented from flowing through the outlet and a second state in which fluid can flow through the outlet. The injection device further includes a flow regulator to control the flow rate of fluid in fluid connection with the outlet. The container, the pressurizing mechanism, the actuator and the flow regulator can be MR compatible, thereby making the device suitable for use in or near the bore of an MR scanner.
