Abstract

A catheter balloon arrangement for application in tortuous blood vessels. First and second spiraled balloons are coupled to a catheter body portion. The spiraled balloons can have first and second apexes with a pitch length there between configured to encourage tortuous compatibility between the catheter balloon arrangement and a body lumen. A method of treatment with an embodiment of a catheter balloon arrangement is also provided.

Claims

1. An apparatus comprising:

an elongated catheter body portion;

a first spiraled balloon about said elongated catheter body portion; and

a second spiraled balloon about said elongated catheter body portion, wherein said first and second spiraled balloons have separate inflation sources.

2. The apparatus of claim 1 wherein said first spiraled balloon runs parallel said second spiraled balloon about said elongated catheter body portion.

3. The apparatus of claim 1 further comprising:

a first apex of said first spiraled balloon;

a second apex of said second spiraled balloon; and

a pitch length between said first apex and said second apex, said pitch length to encourage tortuous compatibility between said apparatus and a tortuous body lumen at said pitch length when said apparatus is inflated within said tortuous body lumen.

4. The apparatus of claim 1 wherein said first spiraled balloon is inflatable to a first size and said second spiraled balloon is inflatable to a second size when said first balloon is inflated to said first size, said first size different than said second size to enhance perfusion of a body fluid past said apparatus when inflated within a body lumen.

5. The catheter balloon arrangement of claim 4 wherein said first size and said second size are predetermined sizes.

6. The apparatus of claim 4 further comprising:

a first inflation lumen coupled to said first spiraled balloon; and

a second inflation lumen coupled to said second spiraled balloon.

7. A catheter balloon arrangement comprising:

a catheter body portion;

a first spiraled balloon coupled to said catheter body portion and having a first apex;

a second spiraled balloon coupled to said catheter body portion and having a second apex; and

a variable pitch length between said first apex and said second apex, said pitch length to encourage tortuous compatibility between said catheter balloon arrangement and a tortuous body lumen when said catheter balloon arrangement is inflated within said tortuous body lumen.

8. The catheter balloon arrangement of claim 7 wherein said first spiraled balloon is inflatable to a first size and said second spiraled balloon is inflatable to a second size when said first balloon is inflated to said first size, said first size different than said second size to enhance perfusion of a body fluid past said catheter balloon arrangement when inflated within a body lumen.

9. The catheter balloon arrangement of claim 8 wherein said first size and said second size are predetermined sizes.

10. The catheter balloon arrangement of claim 8 further comprising:

a first inflation lumen coupled to said first spiraled balloon; and

a second inflation lumen coupled to said second spiraled balloon.

11. A method comprising:

advancing a deflated catheter balloon arrangement through a body lumen to a treatment site, said catheter balloon arrangement including a first spiraled balloon and a second spiraled balloon about an elongated catheter body portion, said first and second spiraled balloons having separate inflation sources;

inflating said catheter balloon arrangement; and

treating said body lumen at said treatment site.

12. The method of claim 11 wherein said treating further comprises delivering radiotherapy to said treatment site via said catheter balloon arrangement.

13. The method of claim 11 wherein said body lumen is a tortuous body lumen, said first spiraled balloon includes a first apex, said second spiraled balloon includes a inflation medium via a second inflation to achieve a second size, said first size different from said second size to enhance said perfusing.

14. The method of claim 11 further comprising perfusing a body fluid past said catheter balloon arrangement during said treating.

15. The method of claim 14 wherein said inflating further comprises:

filling said first spiraled balloon with a first inflation medium via a first inflation lumen to achieve a first size of said first spiraled balloon; and

filling said second spiraled balloon with a second inflation medium via a second inflation to achieve a second size, said first size different from said second size to enhance said perfusing.

16. A catheter balloon arrangement comprising:

a catheter body portion;

a first spiraled balloon coupled to said catheter body portion and having a first apex;

a second spiraled balloon coupled to said catheter body portion and having a second apex, said first and second spiraled balloons having separate inflation sources; and

a variable pitch length between said first apex and said second apex, said pitch length to encourage tortuous compatibility between said catheter balloon arrangement and a tortuous body lumen when said catheter balloon arrangement is inflated within said tortuous body lumen.

17. An apparatus comprising:

an elongated catheter body portion;

a first spiraled balloon about said elongated catheter body portion; and

a second spiraled balloon about said elongated catheter body portion, wherein said first spiraled balloon is inflatable to a first size and said second spiraled balloon is inflatable to a second size when said first balloon is inflated to said first size, said first size different than said second size to enhance perfusion of a body fluid past said apparatus when inflated within a body lumen.

18. The catheter balloon arrangement of claim 17 wherein said first size and said second size are predetermined sizes.

19. The apparatus of claim 17 further comprising:

a first inflation lumen coupled to said first spiraled balloon; and

a second inflation lumen coupled to said second spiraled balloon.

20. A catheter balloon arrangement comprising:

a catheter body portion;

a first spiraled balloon coupled to said catheter body portion and having a first apex;

a second spiraled balloon coupled to said catheter body portion and having a second apex; and

a pitch length between said first apex and said second apex, said pitch length to encourage tortuous compatibility between said catheter balloon arrangement and a tortuous body lumen when said catheter balloon arrangement is inflated within said tortuous body lumen, wherein said first spiraled balloon is inflatable to a first size and said second spiraled balloon is inflatable to a second size when said first balloon is inflated to said first size, said first size different than said second size to enhance perfusion of a body fluid past said catheter balloon arrangement when inflated within a body lumen.

21. The catheter balloon arrangement of claim 20 wherein said first size and said second size are predetermined sizes.

22. The catheter balloon arrangement of claim 20 further comprising:

a first inflation lumen coupled to said first spiraled balloon; and

a second inflation lumen coupled to said second spiraled balloon.

23. A method comprising:

advancing a deflated catheter balloon arrangement through a body lumen to a treatment site, said catheter balloon arrangement including a first spiraled balloon and a second spiraled balloon about an elongated catheter body portion;
