Abstract

A method for draining and sealing a pseudo aneurysm in which a guide wire is inserted over a needle. Then a multi-lumen catheter is inserted over the guide wire. The catheter is used to occlude the vessel puncture and inhibit the flow of fluids between the vessel and the pseudo aneurysm. The pseudo aneurysm is then aspirated and the vessel puncture is allowed to clot and heal.

19. The method of claim 14, wherein said shaft reinforcing components comprise one or more wires.

20. The method of claim 14, wherein said shaft reinforcing components comprise one or more tubing layers.

21. The method of claim 14, wherein said catheter is reinforced by irradiation.

22. The method of claim 14, wherein said shaft reinforcing components comprise a catheter wall having variable thickness.

23. The method of claim 14, wherein said catheter comprises a distal section and a proximal section and wherein said distal section and said proximal section comprise different materials.

24. The method of claim 23, wherein the material of said distal section is more atraumatic than the material of said proximal section.

25. The method of claim 11, further comprising the step of injecting a material that is too viscous to seep through the vessel puncture.

26. The method of claim 11, wherein the catheter shaft comprises a shaped profile that can provide varying resistance as it is inserted through a vessel puncture.

27. The method of claim 26, wherein said shaped profile has an hour glass or peanut shape.

28. A method of draining a pseudo aneurysm and sealing the related blood vessel, said method comprising the steps of:

inserting a needle into a blood vessel;

advancing a guide wire through the needle;

inflating one or more balloons to occlude a blood vessel puncture to inhibit fluid transfer between the blood vessel and the pseudo aneurysm sack;

aspirating the pseudo aneurysm sack; and
