Abstract

A system and method for injecting fluids during angiographic procedures. A finger activated control pad is used to regulate the injection of fluids by a single operator who simultaneously manipulates the primary catheterization equipment.

Claims

1. An angiographic fluid control system which comprises:

a) a catheter;

b) at least one fluid reservoir which contains a contrast medium;

c) a manifold in communication with said catheter and reservoir for passage of said contrast medium;

d) a pumping device that pumps said contrast medium from said reservoir through said manifold; and

e) a control unit which communicates with said pumping device wherein said control unit has a communications pad that is adapted to be manually activated by an operator'"'"'s fingers for the precise pumping of said contrast medium, said communications pad further comprising switches that selectively engage said pumping device.

2. The control system of claim 1 wherein said control unit is mounted onto the catheter.

3. The control system of claim 1 wherein said control unit is mounted on a mechanical arm.

4. The control system of claim 1 wherein said control unit is mechanical.

5. The control system of claim 1 further including a microprocessor wherein said control unit is in communication with the microprocessor.

6. The control system of claim 1 wherein said manifold contains no stopcocks.

7. The control system of claim 1 wherein said control unit is mounted on a platform.

8. The control system of claim 1 wherein said catheter is an angioplasty catheter.

9. The control system of claim 1 wherein said catheter is a vascular access sheath.
