Abstract

A method for extirpating a thrombus from an aorta, comprising positioning a detachment device proximal to a thrombus inside an intact portion of an aorta moving said detachment device to contact said thrombus so as to detach said thrombus from said aortic wall and extirpating said detached thrombus from said lumen.

subsequent to said positioning, expanding said expandable detachment device.

6. The method according to claim 5, wherein said expanding is initiated prior to said moving.

7. The method according to claim 5, wherein said expanding is substantially a part of said moving.

8. The method according to claim 4, wherein said expandable detachment device comprises a first inflatable balloon.

9. The method according to claim 8, further comprising:

subsequent to said positioning, inflating said inflatable balloon.

10. The method according to claim 9, wherein said inflation is initiated prior to said moving.

11. The method according to claim 9, wherein said inflation is substantially a part of said moving.

12. The method according to claim 1, further including closing a lumen of at least one artery branching off said aortic lumen.

13. The method according to claim 12, further including:

making an incision distal to said thrombus, said incision being made into at least one of;

the aortic lumen; and

a lumen of a artery branching off said aortic lumen.

14. The method according to claim 13, further including:

proximally passing a first guide wire from said incision through said aortic lumen to a position that is proximal to said thrombus.

15. The method according to claim 14, wherein said first balloon includes an interior that

communicates with a lumen of a first catheter and including;

passing said first catheter and said first balloon through said incision.

16. The method according to claim 15, further including:

operatively associating said first guide wire with at least one of;

said first balloon; and

said first catheter.

17. The method according to claim 16, including:

inflating said first balloon using said first catheter.

18. The method according to claim 17, including:

expanding said first balloon until said first balloon substantially occludes said aortic lumen.

19. The method according to claim 18, wherein said moving of said detachment device comprises pulling said catheter distally until said first balloon contacts said thrombus.

20. The method according to claim 19, including

manipulating said first balloon against said thrombus during said severing.

21. The method according to claim 20, wherein said first catheter is employed for said manipulation.

22. The method according to claim 20, including

wherein said first guide wire is employed for said manipulation.

23. The method according to claim 22, further including:

deflating said first balloon.

24. The method according to claim 23, further including:

pulling said first catheter distally until a substantial portion of said first catheter is protruding from said incision.

25. The method according to claim 24, further including:

removing said first guide wire from said incision.

26. The method according to claim 25, further including:

pulling said catheter distally; and

removing said first balloon from said incision.

27. The method according to claim 26, further including:

prior to said extirpating said detached thrombus from said lumen, allowing said detached thrombus to float distally toward said incision.

28. The method according to claim 27, further including:

inserting a second guide wire through said incision; and

passing said second guide wire distal to said thrombus.

29. The method according to claim 28, further including:

passing a second balloon through said incision and distal to said thrombus.

30. The method according to claim 29, wherein said second balloon includes an interior that communicates with a second catheter lumen.

31. The method according to claim 30, further including:

operatively associating said second guide wire with at least one of;

said second balloon; and

said second catheter.

32. The method according to claim 31, further including:

inflating said second balloon in a first inflating operation.

33. The method according to claim 32, further including:

pulling said second catheter distally until said second balloon is contacting said thrombus.

34. The method according to claim 33, further including:

manipulating said second catheter while said second balloon is contacting said thrombus.

35. The method according to claim 34, further including:

continuing said manipulation until said thrombus is contacting at least a portion of said incision.

36. The method according to claim 8, wherein at least a portion of said first balloon comprises latex.

37. The method according to claim 8, wherein said first balloon is adapted to substantially fill said lumen upon inflation.

38. The method according to claim 15, wherein said first balloon and said first catheter together comprise at least one of:

an aortic balloon catheter

a Foley catheter; and

a Fogerty catheter.

39. The method according to claim 29, wherein at least a portion of said second balloon comprises latex and said second balloon is adapted to substantially fill said aortic lumen upon inflation.

40. The method according to claim 39, wherein said second balloon and said second catheter comprise at least one of:

an aortic balloon catheter

a Foley catheter; and

a Fogerty catheter.

41. The method according to claim 2, wherein said monitoring a location of said thrombus includes using a probe placed in an esophagus, said probe adapted and positioned to monitor in a transoesophagael position.

42. The method according to claim 41, wherein said probe is adapted to transmit and receive ultrasound signals.

43. The method according to claim 42, including:

transmitting and receiving ultrasound signals from said probe during said monitoring.
