Abstract

A device and method for treating bodily diseases and/or conditions, for example, varicose veins, tumors and aneurysms 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 device comprising:

an expandable cap adapted to block a vessel having an bottom and an opening; and

an anchoring mechanism having a plurality of catching elements connected to a rim of said opening of said expandable cap and adapted to engage with a vessel wall of said vessel, wherein each one of said plurality of catching elements comprises an array of angled spikes pointing toward a plane crossing said bottom perpendicularly to a longitudinal axis of said expandable cap; and

a hook shaped mechanism mechanically connected to said expandable cap at said bottom and adapted to be connected to an extraction hook or wire;

wherein said hook shaped mechanism having a first end connected to said bottom of said expandable cap, and a second end adapted to be connected to said extraction hook or said wire, wherein said second end radiates from said first end towards said opening; and

wherein the hook shaped mechanism has an extraction hook encircled by said expandable cap.

2. The vessel blocking device of claim 1, wherein said expandable cap comprises a concave blocking element.

3. The vessel blocking device of claim 2, wherein the hook shaped mechanism is connected at the bottom of said concave blocking element.

4. The vessel blocking device of claim 1, wherein the vessel blocking device is delivered into said vessel in a folded state.

5. The vessel blocking device of claim 1, further comprising a base, wherein the blocking device is located at the distal tip of an insertion device and a balloon being disposed between the expandable cap and said base.

6. The vessel blocking device of claim 1, wherein the expandable cap is concave, and wherein the expandable cap is expandable so that a rim of the expandable cap extends outwards towards vessel walls.

7. The vessel blocking device of claim 1, further comprising a base expandable outwards towards vessel walls.

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

9. The vessel blocking device of claim 8, wherein pressure is provided by balloon inflation.

10. The vessel blocking device of claim 1, wherein pressure stored within the expandable cap expands outwards towards the vessel walls.

11. The vessel blocking device of claim 10, wherein pressure is provided by a stent like mechanism.

12. The vessel blocking device of claim 10, wherein pressure is provided by a coil like mechanism.

13. The vessel blocking device of claim 1, further comprising a base, wherein said base comprises an anchoring mechanism to anchor the expandable cap to the vessel walls.

14. The vessel blocking device of claim 13, wherein anchoring mechanism comprises a rim expandable towards a vessel.

15. The vessel blocking device of claim 1, comprising an absorbable wire.

16. The vessel blocking device of claim 15, wherein the absorbable wire is coated with occluding agent.

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

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

19. The vessel blocking device of claim 1, wherein the device is constructed from biodegradable materials.
