Abstract

Fluid delivery systems capable of introducing first and second fluids into first and second lumens of a multi-lumen catheter are provided. The first and second fluids are generally a dissolution fluid and a dissolution fluid attenuating fluid. Also provided are fluid delivery devices and kits that include the subject systems. The subject fluid delivery systems find use in a variety of different applications, and are particularly suited for use in the chemical ablation of internal vascular lesions.

Claims

1. A fluid delivery system for delivering at least two different fluids into separate lumens of a multi-lumen catheter, said system comprising:

a first fluid reservoir comprising a dissolution fluid; and

a second fluid reservoir comprising a dissolution fluid attenuating fluid.

2. The system according to claim 1, wherein said system comprises a separate fluid dispensing means for each of said dissolution fluid and dissolution fluid attenuating fluid.

3. The system according to claim 2, wherein each of said fluid dispensing means is a metered fluid dispensing means.

4. The system according to claim 1, wherein said system comprises a single fluid dispensing means for each of said at least two different fluids.

5. The system according to claim 4, wherein said single fluid dispensing means is a metered fluid dispensing means.

6. A system for flushing an internal site with two different fluids, said system comprising:

(a) a multi-lumen catheter;

(b) a fluid delivery system according to claim 1;

and

(c) a negative pressure means sufficient to aspirate fluid from a lumen of said multi-lumen catheter.

7. The system according to claim 6, wherein said fluid delivery system comprises a separate first and second fluid dispensing means.

8. The system according to claim 7, wherein said first and second fluid dispensing means are metered fluid dispensing means.

9. The system according to claim 6, wherein said fluid delivery system comprises a single fluid dispensing means comprising first and second fluid reservoirs.

10. The system according to claim 9, wherein said single fluid dispensing means is a metered fluid dispensing means.

11. The system according to claim 10, wherein said metered dispensing means comprises a cartridge that includes first and second fluid reservoirs.

12. The system according to claim 11, wherein said metered dispensing means comprises a means for increasing the internal pressure of each of said first and second fluid reservoirs.

13. The system according to claim 12, wherein said means for increasing the internal pressure of each of said first and second fluid reservoirs comprises a separate compression means for each of said first and second fluid reservoirs.

14. The system according to claim 12, wherein said means for increasing the internal pressure of each of said first and second fluid reservoirs comprises a single compression means for each of said first and second fluid reservoirs.

15. The system according to claim 6, wherein said system further comprises a balloon inflation means.

16. A system for simultaneously flushing an internal site with two different fluids, said system comprising;

(a) a multi-lumen catheter comprising first, second and third lumens;

(b) a metered fluid delivery system comprising a first reservoir containing a dissolution fluid and a second reservoir containing a dissolution fluid attenuating fluid, wherein said metered fluid delivery means is capable of delivering said first and second fluids into said first and second lumens of said multi-lumen catheter at substantially the same flow rate;

(c) a negative pressure means sufficient to aspirate fluid from said third lumen of said multi-lumen catheter;

(d) a balloon inflation means.

17. The system according to claim 16, wherein said metered fluid delivery system comprises a means for increasing the internal pressure of each of said first and second fluid reservoirs.

18. The system according to claim 17, wherein said means for increasing the internal pressure of each of said first and second fluid reservoirs comprises a separate compression means for each of said first and second fluid reservoirs.

19. The system according to claim 17, wherein said means for increasing the internal pressure of each of said first and second fluid reservoirs comprises a single compression means for each of said first and second fluid reservoirs.

20. The system according to claim 17, wherein said first and second fluid reservoirs are present in a cartridge.
