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.

1. An integrated catheter and powered injector system, comprising:
a pump system housed in a self-contained unit, the pump system comprising:
a motorized pump drive sub-system;a pump electrically connected to and operated by the pump drive sub-system, the pump having a input and an output; anda battery electrically connected to and powering the pump drive sub-system; a contrast media supply removably connected to the pump system by at least one fluid supply line and containing contrast media fluid; an extension line shaped to removably connect an arterial catheter to the pump system; and a control device operatively connected to the pump system to allow a user to send control signals to the pump system such that, in response to control signals received from the control device, the pump drive sub-system drives the pump to:
draw the contrast media fluid from the contrast media supply into the input of the pump through the at least one fluid supply line; andinject 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.
