Abstract

A device and method for treating bodily diseases and/or conditions, for example, varicose veins, tumors and aneutisms including for example insertion of a blocking device toward a target destination using a catheter and delivery of sclerosing or other agents to the vessel while maintaining minimal, for example zero pressure in the treatment area, The blocking device may prevent treatment materials, embolisms, debris etc., from entering the upstream section of vessel. The blocking device may include, for example, a cap or other concave shape and may be expandable or extendible towards the vessel walls.

Claims

1. A vessel blocking implant device comprising:

an expandable plug adapted to block a vessel and made of a memory shape material defining a collapsed state; and

an anchoring mechanism having a plurality of catching elements connected to the expandable plug and adapted to permanently engage with a vessel wall of said vessel;

wherein the expandable plug is adapted to expand within said vessel and to collapsed by itself to said collapsed state within the vessel subsequent to the engagement of said plurality of catching elements with said vessel wall, thereby fusing the vessel wall around the plug and occluding the vessel;

wherein said expandable plug comprises a cap and a base to stabilize the cap in a vessel.

2. The device of claim 1, comprising an inflatable balloon disposed between the cap and the base.

3. The device of claim 2, wherein the cap partially surrounds the balloon.

4. The device of claim 2, wherein the base partially surrounds the balloon.

5. The device of claim 2, wherein the device is located at the distal tip of an insertion device, and the cap is distal to the insertion device, the balloon being disposed between the cap and the base.

6. The device of claim 2, comprising a channel for remotely inflating and deflating a balloon.

7. The device of claim 1, wherein the cap is concave, and wherein the cap is expandable so that a rim of the cap can extend outwards towards vessel walls.

8. The device of claim 1, wherein the base is expandable outwards towards vessel walls.

9. The device of claim 1, wherein an increase in pressure in the inner portion of the cap causes the cap to expand outwards towards the vessel walls.

10. The device of claim 9, wherein pressure is provided by balloon inflation.

11. The device of claim 1, wherein pressure stored within the cap causes the cap to expand outwards towards the vessel walls.

12. The device of claim 1, wherein said anchoring mechanism is sized and shaped to anchor the cap to the vessel walls.

13. The device of claim 12, wherein said plurality of catching elements of said anchoring mechanism comprises spikes.

14. The device of claim 1, comprising a pullable mechanism to extract the device from a vessel.

15. The device of claim 1, wherein said vessel blocking implant device is delivered by a catheter device.

16. The catheter device of claim 15, wherein said catheter device comprises a guidewire.

17. The device of claim 15, wherein said catheter device comprises a drug dispensing mechanism.

18. The device of claim 1, wherein said catching elements are adapted to catch the vessel wall.

19. The device of claim 1, wherein said catching elements are adapted to be locked in the vessel wall.

20. The device of claim 1, wherein said vessel is a blood vessel.

21. The device of claim 1, wherein the device is sized and shaped for implantation within a vessel.

22. The device of claim 1, wherein the device is constructed from biodegradable materials.
