Abstract

A medical contrast suspension generating delivery apparatus includes a Venturi-agitating tip assembly, a source of pressurized medical carbon dioxide, a source of an iodinated contrast medium, and a dual lumen catheter connecting the Venturi-agitating tip assembly to the source of pressurized medical carbon dioxide and the source of the iodinated contrast medium.

Claims (14)

1. A medical contrast suspension generating delivery apparatus, comprising:

a Venturi-agitating tip assembly;

a source of pressurized medical carbon dioxide;

a source of an iodinated contrast medium;

a dual lumen catheter connecting the Venturi-agitating tip assembly to the source of pressurized medical carbon dioxide and the source of the iodinated contrast medium.

2. The delivery apparatus according to claim 1 , wherein the source of pressurized medical carbon dioxide includes a pressure delivery syringe of a compressed medical fluid unit.

3. The delivery apparatus according to claim 2 , wherein the source of the iodinated contrast medium includes a contrast syringe.

4. The delivery apparatus according to claim 3 , wherein a micro-hose connects the source of pressurized medical carbon dioxide to a first lumen of the dual lumen catheter.

5. The delivery apparatus according to claim 4 , wherein the source of the iodinated contrast medium is connected to a second lumen of the dual lumen catheter to deliver the iodinated contrast medium to the second lumen of the dual lumen catheter.

6. The delivery apparatus according to claim 3 , wherein the contrast syringe includes a one-way valve at its outlet to ensure that the iodinated contrast medium from the contrast syringe only flows out of the contrast syringe.

7. The delivery apparatus according to claim 1 , wherein the source of the iodinated contrast medium includes a contrast syringe.

8. The delivery apparatus according to claim 7 , wherein the contrast syringe includes a one-way valve at its outlet to ensure that the iodinated contrast medium from the contrast syringe only flows out of the contrast syringe.

9. The delivery apparatus according to claim 1 , wherein a micro-hose connects the source of pressurized medical carbon dioxide to a first lumen of the dual lumen catheter.

10. The delivery apparatus according to claim 9 , wherein the source of the iodinated contrast medium is connected to a second lumen of the dual lumen catheter to deliver the iodinated contrast medium to the second lumen of the dual lumen catheter.
