Abstract

A medical fluid suspension generating apparatus for performing medical procedures includes a Venturi-agitating tip assembly composed of a multi-channel arrangement at a proximal first end thereof and a tip at a distal second end thereof. The apparatus also includes a compressed medical fluid unit fluidly connected to the multi-channel arrangement at a proximal first end of the Venturi-agitating tip assembly and a medical solution fluidly connected to the multi-channel arrangement at a proximal first end of the Venturi-agitating tip assembly. Pressurized gas, from the compressed medical fluid unit, and the medical solution are combined within the Venturi-agitating tip assembly in a manner generating an enriched medical suspension that is ultimately dispensed from the suspension delivery apparatus.

Claims

1. An apparatus for creation and delivery of enriched medical suspension, comprising:

a compressed medical fluid unit containing pressurized medical carbon dioxide (CO₂);

a syringe of a medical solution of carbon dioxide (CO₂);

a suspension delivery catheter including a dual lumen catheter connecting a Venturi-agitating tip assembly to the pressurized medical carbon dioxide (CO₂) from the compressed medical fluid unit and the medical solution of carbon dioxide (CO₂) from the syringe;

wherein forcing the pressurized medical carbon dioxide (CO₂) through the Venturi-agitating tip assembly causes the medical solution of carbon dioxide (CO₂) to be drawn into the Venturi-agitating tip assembly such that the pressurized medical carbon dioxide (CO₂) from the compressed medical fluid unit and the medical solution of carbon dioxide (CO₂) from the syringe to mix and form the enriched medical suspension.

2. The apparatus according to claim 1, wherein the compressed medical fluid unit includes an inlet port to which a pressurized gas cylinder containing carbon dioxide (CO₂) is selectively connected and an outlet port in communication with the inlet port.

3. The apparatus according to claim 1, further including a syringe in which the medical solution of carbon dioxide (CO₂) is contained.

4. The apparatus according to claim 3, wherein the syringe includes a one-way valve.

5. The apparatus according to claim 1, wherein the suspension delivery catheter includes a first end having the Venturi-agitating tip assembly and a second end to which the compressed medical fluid unit and the medical solution of carbon dioxide (CO₂) are fluidly connected for the passage of pressurized medical carbon dioxide (CO₂) and medical solution of carbon dioxide (CO₂).

6. The apparatus according to claim 1, wherein pressurized medical carbon dioxide (CO₂) traveling through the Venturi-agitating tip assembly creates negative pressure inside the Venturi-agitating tip assembly such that the medical solution of carbon dioxide (CO₂) mixes with pressurized medical carbon dioxide (CO₂) and forms the enriched medical suspension of carbon dioxide (CO₂).

7. The apparatus according to claim 6, wherein the Venturi-agitating tip assembly includes a spray tip from which the enriched medical suspension of carbon dioxide (CO₂) is sprayed.

8. The apparatus according to claim 1, wherein the Venturi-agitating tip assembly includes a spray tip from which the enriched medical suspension of carbon dioxide (CO₂) is sprayed.

9. A method for creation and delivery of enriched medical suspension, comprising:

supplying a compressed medical fluid unit containing pressurized medical carbon dioxide (CO₂);

supplying a syringe containing a medical solution of carbon dioxide (CO₂);

forcing the pressurized medical carbon dioxide (CO₂) through a Venturi-agitating tip assembly in a manner drawing the medical solution of carbon dioxide (CO₂) into the Venturing agitating tip assembly and causing the pressurized medical carbon dioxide (CO₂) from the compressed medical fluid unit and the medical solution of carbon dioxide (CO₂) to mix and form the enriched medical suspension.

10. The method according to claim 9, wherein the compressed medical fluid unit includes an inlet port to which a pressurized gas cylinder containing carbon dioxide (CO₂) is selectively connected and an outlet port in communication with the inlet port.

11. The method according to claim 9, further including a syringe in which the medical solution of carbon dioxide (CO₂) is contained.

12. The method according to claim 11, wherein the syringe includes a one-way valve.

13. The method according to claim 9, wherein the compressed medical fluid unit and the medical solution of carbon dioxide (CO₂) and medical solution of carbon dioxide (CO₂) are fluidly connected to the Venturi-agitating tip assembly.

14. The method according to claim 13, wherein the Venturi-agitating tip assembly includes a spray tip from which the enriched medical suspension of carbon dioxide (CO₂) is sprayed.

15. The method according to claim 9, wherein the Venturi-agitating tip assembly includes a spray tip from which the enriched medical suspension of carbon dioxide (CO₂) is sprayed.
