Abstract

An embolic protection system including a first occlusive device having an elongate shaft having a proximal end and distal end. A lumen extending in part through an elongate shaft. Occlusive member disposed proximate distal end of the elongate shaft. Shaft having transversely disposed opening. Second occlusive device including elongate shaft having a proximal end and a distal end. A lumen extending at least in part through the elongate shaft. An occlusive member disposed proximate the distal end of the elongate shaft of the second occlusive device. The second occlusive member being disposed proximate the distal end of the elongate shaft of the second occlusive device. The second occlusive member being disposed in part within the lumen of the first occlusive member.

Claims

1. A method of providing embolic protection, comprising:

providing a first occlusive device including an elongate shaft having a proximal end and a distal end, a lumen extending at least in part through the elongate shaft, and an occlusive member disposed proximate the distal end of the elongate shaft;

providing a second occlusive device including an elongate shaft having a proximal end and a distal end, a lumen extending at least in part through the elongate shaft, and a occlusive member disposed proximate the distal end of the elongate shaft, and the second occlusive member being disposed at least in part within the lumen of the elongate shaft of the first occlusive member;

advancing the first occlusive member distal a target site in a renal artery; and

advancing the second occlusive device to a branch vessel of the renal artery.

2. The method of providing embolic protection in accordance with claim 1, wherein the second occlusive device is advanced to proximate the ostium of the branch vessel, while being disposed within the first occlusive device.

3. The method of providing embolic protection in accordance with claim 1, wherein the first occlusive member includes a filter.

4. The method of providing embolic protection in accordance with claim 1, wherein the occlusive member of the second occlusive device includes a balloon.

5. The method of providing embolic protection in accordance with claim 1, further comprising providing a delivery sheath disposable over the first occlusive member.

6. The method of providing embolic protection in accordance with claim 5, further comprising moving the delivery sheath proximally relative to the first occlusive member to allow the first occlusive member to expand transversely from a compressed position to an expanded position transversing the renal artery.

7. The method of providing embolic protection in accordance with claim 1, further comprising advancing the second occlusive member out of a generally transverse opening in the first occlusive device into the branch vessel.

8. The method of providing embolic protection in accordance with claim 7, wherein the second occlusive member includes a balloon.

9. The method of providing embolic protection in accordance with claim 8, further comprising of inflating the balloon to include the branch vessel.

10. An embolic protection filter, comprising:

an elongate shaft, having a proximal end and a distal end, a lumen extending at least in part therethrough;

a filter element disposed proximate the distal end of the shaft; and

the shaft having a generally transversely oriented opening into the lumen, proximate the distal end of the shaft.

11. The embolic protection filter in accordance with claim 10, wherein the shaft comprises the hypotube having an outer diameter of 0.015 to 0.020 inches.

12. The embolic protection filter in accordance with claim 11, wherein the outer diameter of the shaft is 0.016 to 0.019 inches.

13. The embolic protection filter in accordance with claim 12, wherein the outer diameter of the shaft is 0.018 inches.

14. The embolic protection filter in accordance with claim 10, wherein the transverse opening is located 0 to 5 cm from the distal end of the shaft.

15. The embolic protection filter in accordance with claim 14, wherein the transverse opening is located 0 to 3 cm from the distal end of the elongate shaft.

16. The embolic protection filter in accordance with claim 15, wherein the transverse opening is located 0 to 2 cm from the distal end of the elongate shaft.

17. The embolic protection filter in accordance with claim 10, wherein the transverse opening has a length and a width.

18. The embolic protection filter in accordance with claim 17, wherein the length of the transverse opening is between 0.5 and 3.0 cm.

19. An embolic protection system, comprising:

the first occlusive device including an elongate shaft having a proximal end and a distal end, a lumen extending at least in part through the elongate shaft, an occlusive member disposed proximate the distal end of the elongate shaft, and the shaft having a generally transversely disposed opening;

a second occlusive device including an elongate shaft having a proximal end and a distal end, a lumen extending at least in part through the elongate shaft, and an occlusive member disposed proximate the distal end; and

a second occlusive member being disposed proximate the distal end of the elongate shaft of the second occlusive device, and being disposed at least in part within the lumen of the first occlusive member.

20. The embolic protection system in accordance with claim 19, wherein the first occlusive member includes a filter.

21. The embolic protection system in accordance with claim 19, wherein the second occlusive member includes a balloon in fluid communication with the lumen of the second occlusive device.

22. The embolic protection system in accordance with claim 19, the second occlusive member being disposed within the lumen of the first occlusive device.

23. The embolic protection system in accordance with claim 19, wherein the elongate member of the second occlusive device includes a hypotube.

24. The embolic protection system of claim 23, wherein the outer diameter of the elongate member of the second occlusive device is between 0.010 to 0.015 inches.

25. The embolic protection system of claim 24, wherein the outer diameter of the elongate member of the second occlusive device is approximately 0.012 inches.

26. The embolic protection filter in accordance with claim 19, wherein the shaft comprises the hypotube having an outer diameter of 0.015 to 0.020 inches.

27. The embolic protection filter in accordance with claim 26, wherein the outer diameter of the shaft is 0.016 to 0.019 inches.

28. The embolic protection filter in accordance with claim 27, wherein the outer diameter of the shaft is 0.018 inches.

29. The embolic protection filter in accordance with claim 19, wherein the transverse opening is located 0 to 5 cm from the distal end of the shaft.

30. The embolic protection filter in accordance with claim 29, wherein the transverse opening is located 0 to 3 cm from the distal end of the elongate shaft.
