Abstract

An injector system includes a powered injector, a pressurizing chamber in operative connection with the powered injection, a fluid path in fluid communication with the pressurizing chamber, and a manual control in fluid connection with the fluid path. The manual control includes at least one actuator for controlling the injector through application of force by an operator. The actuator provides tactile feedback of pressure in the fluid path to the operator via a fluid connection therewith. An injection system for use in angiography includes a source of saline, a pump in fluid connection with the source of saline to pressurized the saline, a source of contrast, a contrast valve in fluid connection with the source of contrast, a powered injector in fluid connection with the contrast valve, and a pressure isolation mechanism.
