Abstract

Systems and methods for treating septal defects. A system for treating septal defects may comprise a first catheter having a distal end and a first lumen, a second catheter having a distal end a second lumen, a bridge member extending between the distal end of the first catheter and the distal end of the second catheter, and a first patch adapted to be disposed within the first lumen and movable out of the first lumen along the bridge member. A second patch may be used and be connectable to the first patch.

Claims

1. A system for treating septal defects, comprising:

a first catheter having a distal end and a first lumen;

a second catheter having a distal end and a second lumen;

a bridge member extending between the distal end of the first catheter and the distal end of the second catheter, wherein the bridge member is disposed within both the first lumen and the second lumen; and

a first patch adapted to be disposed within the first lumen and movable out of the first lumen along the bridge member.

2. The system in accordance with claim 1, wherein the distal end of the first catheter and the distal end of the second catheter face each other.

3. The system in accordance with claim 1, further comprising a second patch adapted to be disposed within the second lumen and movable out of the second lumen along the bridge member.

4. The system in accordance with claim 3, wherein the first patch and the second patch are connectable.

5. The system in accordance with claim 1, wherein the first patch further comprises a hook.

6. The system in accordance with claim 5, wherein the second patch includes a loop.

7. The system in accordance with claim 1, wherein the first patch includes an adhesive.

8. The system in accordance with claim 7, wherein the adhesive includes fibrigen.

9. The system in accordance with claim 7, wherein the adhesive includes fibrin glue.

10. The system in accordance with claim 7, wherein the adhesive includes cyanoacrylate.

11. The system in accordance with claim 1, wherein the first patch further comprises a shank.

12. The system in accordance with claim 11, wherein the first patch further comprises threads.

13. The system in accordance with claim 11, wherein the first patch further comprises one or more rings disposed on the shank defining a recess therebetween.

14. The system in accordance with claim 13, wherein the second patch further comprises a deflectable flange.

15. The system in accordance with claim 1, further comprising a first pusher to urge the first patch out of the first lumen along the bridge member.

16. The system in accordance with claim 15, wherein the first patch and the first pusher have mating ends.

17. A method for treating septal defects, comprising the steps of:

providing a first catheter including a first lumen;

advancing the first catheter through the vasculature of a patient to a first side of a septal defect;

providing a second catheter including a second lumen;

advancing the second catheter through the vasculature of a patient to a second side of the septal defect;

passing a bridge member from the first lumen into the second lumen, the bridge member spanning between the first catheter and the second catheter and passing through the septal defect; and

passing a first patch from the first lumen over the bridge member to the first side of the septal defect.

18. The method in accordance with claim 17, wherein the step of advancing the first catheter through the vasculature of a patient to a first side of a septal defect includes passing the first catheter through an atrium.

19. The method in accordance with claim 17, wherein the step of advancing the second catheter through the vasculature of a patient to a second side of a septal defect includes passing the second catheter through an atrium.

20. The method in accordance with claim 17, wherein the first catheter is located on the first side of the septal defect in an atrium.

21. The method in accordance with claim 17, wherein the first catheter is located on the first side of the septal defect in a ventricle.

22. The method in accordance with claim 17, further comprising the step of passing a second patch from the second lumen over the bridge member to the second side of the septal defect.

23. The method in accordance with claim 22, further comprising the step of connecting the first patch and the second patch.

24. A method for treating septal defects, comprising the steps of:

providing a first catheter including a first lumen;

advancing the first catheter through the vasculature of a patient to a first side of a septal defect;

providing a second catheter including a second lumen;

advancing the second catheter through the vasculature of a patient to a second side of the septal defect;

passing a bridge member from the first lumen into the second lumen, the bridge member spanning between the first catheter and the second catheter and passing through the septal defect;

urging a first patch from the first lumen over the bridge member to the first side of the septal defect with a first pusher;

urging a second patch from the second lumen over the bridge member to a second side of the septal defect with a second pusher; and

connecting the first patch and the second patch across the septal defect.

25. The method in accordance with claim 24, wherein the step of advancing the first catheter through the vasculature of a patient to a first side of a septal defect includes passing the first catheter through an atrium.

26. The method in accordance with claim 24, wherein the step of advancing the second catheter through the vasculature of a patient to a second side of a septal defect includes passing the second catheter through an atrium.

27. The method in accordance with claim 24, wherein the first catheter is located on the first side of the septal defect in an atrium.

28. The method in accordance with claim 24, wherein the first catheter is located on the first side of the septal defect in a ventricle.
