Abstract

The present invention relates to a dual balloon catheter with controlled expansion and solution flow, a multi-port manifold and a dual syringe delivery device and method with intended use in sclerotherapy.

Claims (37)

1. A dual balloon dual syringe delivery device with commonly actuable reservoirs for each solution component, comprising:

a manifold;

a multi-lumen tube having a distal tip;

an inner balloon;

an outer balloon;

a plunger;

a cradle;

a holster;

the manifold comprising: a first solution channel and a second solution channel;

a solution channel insert;

a retainer cap;

wherein the first solution channel and the second solution channel are non-converging;

wherein the solution channel insert is in direct mating relationship with a distal portion of the manifold;

wherein the retainer cap is in direct mating relationship with the distal portion of the manifold;

wherein the solution channel insert is in direct mating relationship with the proximal portion of the multi-lumen tube and having apertures through which fluids are dispensed into the multi-lumen tube;

wherein the multi-lumen tube is in direct mating relationship with the inner and outer balloons;

wherein the multi-lumen tube having a first solution lumen in fluid connection with said first solution channel, a second solution lumen in fluid connection with said second solution channel, and a central longitudinal lumen;

wherein the multi-lumen tube having at the proximal end a first solution inlet in fluid connection with said first solution lumen, and a second solution inlet in fluid connection with said second solution lumen;

wherein the first solution lumen further comprises a first plurality of exhaust orifices configured to be fluidly connected to the inner balloon, and the second solution lumen further comprises a second plurality of exhaust orifices configured to be fluidly connected to the outer balloon;

wherein the inner balloon having an inner surface and an outer surface void of any orifices;

wherein the outer balloon having an inner surface and an outer surface arrayed with multiples of orifices;

wherein the plunger having a proximal head and a distally extending shaft that joins with an aperture in the cradle;

wherein the cradle having a proximal flange and a distally extending body which joins with an aperture of the holster;

wherein the holster having a proximal flange, a distally extending body, and an interior aperture.

2. The manifold of claim 1 , further comprising a plurality of recessed groove elements sized to receive corresponding protrusions on the solution channel insert which insures proper alignment.

3. The manifold of claim 1 , wherein the retainer cap comprises a central longitudinal orifice.

4. The manifold of claim 1 , wherein the solution channel insert comprises a first channel in fluid connection with the first solution channel, and a second channel in fluid connection with the second solution channel.

5. The manifold of claim 1 , wherein female locking luer is provided at the proximal end of each of the first solution channel and the second solution channel.

6. The manifold of claim 1 , wherein female slip luer is provided at the proximal end of each of the first solution channel and the second solution channel.

7. The plunger of claim 1 , wherein the plunger proximal head is configured to receive a hypodermic syringe plunger head.

8. The plunger of claim 1 , wherein the plunger proximal head provides for actuating the fluid solution reservoirs.

9. The plunger of claim 1 , wherein the shaft is in direct mating relationship with the cradle.

10. The cradle of claim 1 , wherein the body is in direct mating relationship with the holster.

11. The cradle of claim 1 , wherein the body is in direct mating relationship with a syringe finger tab.

12. The holster of claim 1 , wherein the body is in direct mating relationship with the manifold.

13. The multi-lumen tube of claim 1 , wherein the sizing and number of distal apertures control a rate of solution flow, and a rate of balloon expansion.

14. The multi-lumen tube of claim 1 , wherein the distal tip is a separate component in direct mating relationship with the multi-lumen tube.
