Abstract

A balloon catheter may be provided with multiple balloons. At least one of the balloons may include at least one blade. The multiple balloons may be inflated by a common inflation lumen, or by separate inflation lumens. In some embodiments, a predilation balloon may be provided to predilate a lesion prior to placement of a bladed balloon within the lesion.

Claims

1. A balloon catheter comprising:

a catheter shaft having an inflation lumen extending therethrough;

a first inflatable balloon having at least one blade, an interior portion of the first inflatable balloon being in fluid communication with the inflation lumen; and

a second inflatable balloon.

2. The balloon catheter of claim 1, wherein an interior portion of the second inflatable balloon is in fluid communication with the inflation lumen.

3. The balloon catheter of claim 2, wherein the second inflatable balloon further comprises at least one blade.

4. The balloon catheter of claim 1, further comprising a third inflatable balloon.

5. The balloon catheter of claim 4, wherein an interior portion of the third inflatable balloon is in fluid communication with the inflation lumen.

6. The balloon catheter of claim 5, wherein the third inflatable balloon further comprises at least one blade.

7. The balloon catheter of claim 4, further comprising a fourth inflation balloon.

8. The balloon catheter of claim 7, wherein an interior portion of the fourth inflatable balloon is in fluid communication with the inflation lumen

9. The balloon catheter of claim 8, wherein the fourth inflatable balloon further comprises at least one blade.

10. The balloon catheter of claim 7, further comprising a fifth inflatable balloon.

11. The balloon catheter of claim 10, wherein an interior portion of the fifth inflatable balloon is in fluid communication with the inflation lumen.

12. The balloon catheter of claim 11, wherein the fifth inflatable balloon further comprises at least one blade.

13. The balloon catheter of claim 1, wherein the catheter shaft further comprises a second inflation lumen extending therethrough;

an interior portion of the second inflatable balloon being in fluid communication with the second inflation lumen.

14. The balloon catheter of claim 13, further comprising a third inflatable balloon having at least one blade;

wherein the catheter shaft further comprises a third inflation lumen extending therethrough;

an interior portion of the third inflatable balloon being in fluid communication with the third inflation lumen.

15. The balloon catheter of claim 14, further comprising a fourth inflatable balloon having at least one blade;

wherein the catheter shaft further comprises a fourth inflation lumen extending therethrough;

an interior portion of the fourth inflatable balloon being in fluid communication with the fourth inflation lumen.

16. The balloon catheter of claim 15, further comprising a fifth inflatable balloon having at least one blade;

wherein the catheter shaft further comprises a fifth inflation lumen extending therethrough;

an interior portion of the fifth inflatable balloon being in fluid communication with the fifth inflation lumen.

17. A balloon catheter comprising:

a catheter shaft having a first inflation lumen and a second inflation lumen extending therethrough;

a first inflatable balloon, an interior portion of the first inflatable balloon being in fluid communication with the first inflation lumen; and

a second inflatable balloon having at least one blade, an interior portion of the second inflatable balloon being in fluid communication with the second inflation lumen.

18. The balloon catheter of claim 17, wherein the first inflatable balloon is distal to the second inflation balloon.

19. The balloon catheter of claim 17, wherein an expanded diameter of the first inflatable balloon is substantially the same as an unexpanded diameter of the second inflatable balloon.

20. The balloon catheter of claim 17, wherein an expanded diameter of the first inflatable balloon is larger than an unexpanded diameter of the second inflatable balloon.

21. The balloon catheter of claim 20, wherein the expanded diameter of the first inflatable balloon is smaller than an expanded diameter of the second inflatable balloon.

22. A method treating a vascular occlusion comprising:

providing a catheter having a first inflation balloon and a second inflation balloon, the second inflation balloon having at least one blade;

positioning the catheter with the first inflation balloon oriented within a vascular occlusion;

inflating the first inflation balloon to predilate the vascular occlusion;

positioning the catheter with the second inflation balloon oriented within the predilated vascular occlusion; and

inflating the second inflation balloon to fully dilate the predilated vascular occlusion.
