摘要：
Devices and methods are provided for delivering fluid into a patient's body. In an exemplary embodiment, the device may include a syringe cartridge and a syringe driver that may be coupled to the cartridge. The cartridge may include a housing including a proximal end, a distal end, and defining an interior, the cartridge further including a piston slidably disposed within the interior for delivering fluid within the interior through a port in the distal end. The driver may include a plunger for advancing the piston within the interior of the housing, a source of pressurized fluid, a valve, and an actuator member coupled to the valve for selectively opening a flow path from the source to the plunger to control flow of the pressurized fluid to advance the plunger to deliver fluid from the interior of the housing at a desired rate.
