Abstract

A delivery system for an occlusion balloon includes a delivery catheter and a balloon releasably detached thereto. The balloon can include a base portion that is threaded onto the end of the delivery catheter. The balloon can include a one-way valve or septum in the base portion, through which a filling needle is inserted into a cavity of the balloon. The balloon can be filled with a fluid to expand the balloon and fix the balloon within the patient's body. The balloon can be filled with a hardening material to assist in fixing the balloon in place and occluding the blood vessel. The balloon can include anchoring structure on its outer surface to assist in the fixing the location of the balloon. The delivery device and needle can be detached and withdrawn from the balloon, allowing the septum to close and seal the balloon, leaving the balloon fixed within the body vessel.

First claim

What is claimed is:

1. A system for occluding a body vessel, the system comprising: a tubular delivery device having a proximal and distal end and a lumen extending therebetween; a detachable balloon rotatably detachably mounted to the distal end of the tubular delivery device by a thread connection; a one-way valve disposed at a proximal end of the detachable balloon; and a filling tube having an opening at a distal end thereof, the filling tube extending through the delivery device lumen with the filling tube distal end in fluid communication with a cavity defined by the balloon.

2. The system of claim 1 , wherein the balloon includes a base portion and the valve is disposed in the base portion.

3. The system of claim 1 , wherein the balloon includes attachment structure around its outer surface.

4. The system of claim 3 , wherein the attachment structure comprises a stent structure.

5. The system of claim 3 , wherein the attachment structure comprises a plurality of channels extending along the outer surface.

6. The system of claim 3 , wherein the attachment structure comprises a roughened outer surface.

7. The system of claim 1 , wherein the filling tube comprises a needle.

8. The system of claim 1 further comprising a fluid disposed within the cavity defined by the balloon.

9. The system of claim 8 , wherein the fluid comprises a hardening material.

10. The system of claim 1 , wherein the delivery device and the filling tube are coupled together such that the filling tube will rotate along with the delivery device when the delivery device is rotated.

11. The system of claim 1 , wherein the filling tube extends through and beyond the one-way valve and into the detachable balloon.

12. An occlusion balloon apparatus comprising: a tubular delivery device; an expandable balloon including a base portion having an attachment structure for rotatably attaching to the tubular delivery device, the balloon further including an expandable body portion defining an expandable cavity therein, and wherein the attachment structure is a thread; a one-way valve disposed in the base portion arranged for limiting fluid within the cavity from escaping; an anchoring structure extending about an outer surface of the balloon for fixing the balloon to a wall of a body vessel in response to expansion of the balloon; and a filling tube for being coupled to the tubular delivery device, the filling tube extending through and beyond the one-way valve and into the balloon cavity.

13. The apparatus of claim 12 , wherein the valve includes a flap portion arranged to pivot into the cavity.

14. The apparatus of claim 12 , wherein the anchoring structure comprises a plurality of stent rings.

15. The apparatus of claim 12 , wherein the anchoring structure comprises a plurality of channels defining indentation in the body portion of the balloon.

16. The apparatus of claim 12 , wherein the expandable body portion comprises silicone, rubber, or ePTFE.

17. The device of claim 12 , further comprising a delivery device rotatably detachably coupled to the attachment structure of the balloon, wherein the delivery device and the filling tube are coupled together such that the filling tube will rotate along with the delivery device when the delivery device is rotated.

18. A method for delivering an occlusion balloon to a body vessel, the method comprising: inserting, into a patient's body, a delivery device having an expandable balloon rotatably detachably mounted thereto, the balloon including a one-way valve, wherein a needle extends through a lumen of the delivery device and is in fluid communication with a cavity defined by the balloon; delivering the balloon to a body vessel; injecting a fluid into the balloon cavity through the needle; expanding the balloon into engagement with a wall of the body vessel; detaching the balloon from the delivery device by rotating the delivery device relative to the balloon, thereby, decoupling a thread connection between the delivery device and the expandable balloon; withdrawing the needle from the one-way valve; and removing the delivery device and the needle from the patient's body.

19. The method of claim 18 , wherein the fluid comprises a hardening material.

20. The method of claim 18 further comprising expanding the balloon across two blood vessels.

21. The method of claim 18 , wherein an outer surface of the balloon includes an anchoring mechanism for fixing the location of the balloon within the body vessel.

22. The method of claim 18 , wherein the delivery device and the needle are coupled such that the needle and delivery device are rotated, withdrawn, and removed together.

23. The method of claim 18 , wherein the needle extends through and beyond the one-way valve.
