Abstract

The present subject matter describes a balloon catheter and methods of using the balloon catheter. The balloon catheter is particularly useful for pericardiocentesis and percutaneous pericardiotomy.

Claims

1. An apparatus, comprising:

a catheter;

a first inflatable balloon attached to the catheter,

wherein the first inflatable balloon is not at or near the distal end of the catheter, and

wherein the first inflatable balloon is a tulip-shaped balloon that has an axis and comprises a first section proximal to the user being generally conical along the axis, and a second section distal to the user being generally half-spherical along the axis, and

a second inflatable balloon attached to the catheter and distal to the first inflatable balloon,

wherein the second inflatable balloon is not at or near the distal end of the catheter.

2. The apparatus according to claim 1, wherein the length of the first section is shorter than the length of the second section.

3. The apparatus according to claim 1, wherein the length of the first section is longer than the length of the second section.

4. The apparatus according to claim 1, wherein the length of the first section is substantially equal to the length of the second section.

5. The apparatus according to claim 1, wherein the inflatable tulip-shaped balloon has a diameter of 5 to 30 mm when fully inflated and a length of 5 to 30 mm when fully inflated.

6. The apparatus according to claim 1, wherein the catheter size ranges from 5 to 15 French.

7. The apparatus according to claim 1, further comprising at least one drainage hole in the catheter.

8. The apparatus according to claim 1, wherein the catheter is a pigtail catheter or a straight catheter.

9. The apparatus according to claim 1, wherein the second inflatable balloon is disk-shaped or spherical.

10. The apparatus according to claim 1, wherein the second inflatable balloon has a maximum inflated diameter smaller than the maximum diameter of the first inflatable balloon, when inflated.

11. The apparatus according to claim 1, wherein the first inflatable balloon and second inflatable balloon are each composed of a material independently selected from the group consisting of polyvinyl chloride, polyethylene terephthalate, nylon, rubber, polyethylene and polyurethane.

12. The apparatus according to claim 1, further comprising at least one lumen in communication with the catheter for inflation and/or deflation of the first inflatable balloon and/or the second inflatable balloon.

13. The apparatus according to claim 1, further comprising a syringe affixed to the catheter for inflation and/or deflation of the first inflatable balloon and/or the second inflatable balloon.

14. The apparatus according to claim 1, further comprising a stop-cock affixed to the catheter for sealing the first inflatable balloon and/or the second inflatable balloon.

15. The apparatus according to claim 1, further comprising a guidewire for placement of the apparatus during operation.

16. The apparatus according to claim 1, further comprising an ultrasound for viewing of the apparatus during operation.

17. The apparatus according to claim 1, wherein the catheter is a braided catheter.

18. A method, comprising:

providing an apparatus, comprising;

a catheter, and

a first inflatable balloon attached to the catheter,

wherein the first inflatable balloon is not at or near the distal end of the catheter, and

wherein the first inflatable balloon is a tulip-shaped balloon that has an axis and comprises a first section proximal to the user being generally conical along the axis, and a second section distal to the user being generally half-spherical along the axis, and

a second inflatable balloon attached to the catheter and distal to the first inflatable balloon,

wherein the second inflatable balloon is not at or near the distal end of the catheter;

advancing the apparatus into a pericardial space;

inflating the first balloon to encompass the pericardial space; and

draining the fluid from the pericardial space.

19. The method according to claim 18, wherein the apparatus further comprises a ultrasound device for viewing catheter placement.

20. The method according to claim 18, further comprising pulling the inflated first inflatable balloon and catheter through the pericardium to enlarge the pericardial space, prior to draining the fluid.

21. The method according to claim 18, further comprising deflating the first inflatable balloon and removing the apparatus from the pericardial space, prior to draining the fluid.

22. The method according to claim 18, wherein the catheter is a pigtail catheter or a straight catheter.

23. A method according to claim 18, further comprising inflating the second inflatable balloon to secure and prevent the catheter from being pulled out of the pericardial space, prior to draining the fluid.

24. The method according to claim 18, further comprising pulling the first inflatable balloon back towards the pericardium to enlarge the pericardial space, prior to draining the fluid.

25. The method according to claim 18, further comprising deflating the first inflatable balloon and second inflatable balloon, and removing the apparatus from the pericardial space, prior to draining the fluid.

26. The method according to claim 18, wherein the catheter is a braided catheter.

27. A kit for pericardiocentesis comprising:

a catheter for draining the pericardial space;

a first inflatable balloon attached to the catheter, for enlarging the pericardial space,

wherein the first inflatable balloon is not at or near the distal end of the catheter, and

wherein the first inflatable balloon is a tulip-shaped balloon that has an axis and comprises a first section proximal to the user being generally conical along the axis, and a second section distal to the user being generally half-spherical along the axis, and

a second inflatable balloon attached to the catheter and distal to the first inflatable balloon, for securing the catheter, wherein the second inflatable balloon is not at or near the distal end of the catheter.
