INTEGRATED CATHETER AND POWERED INJECTOR SYSTEM FOR USE IN PERFORMING RADIAL ANGIOGRAPHY

摘要

An integrated catheter and powered injector system includes a pump housed in a self-contained unit, a contrast media supply removably connected to the pump by a fluid supply line, an extension line removably connecting an arterial catheter to the pump, and a control device sending user control signals to the pump. The pump comprises a motorized pump drive sub- system operating the pump, and a battery electrically connected to and powering the pump drive sub- system. In response to signals received from the control device, the pump drive sub- system drives the pump to draw contrast media fluid from the supply into the pump through the fluid supply line and inject the contrast media fluid from the output of the pump through the extension line and into the arterial catheter at a controlled flow rate and/or pressure.
