Abstract

A venous anchor device operably coupled by graft material to form an anastomotic connector is provided. The venous anchor device includes a tubular main body having a metal frame structure and including a distal end and a proximal end, the distal end including a plurality of barbs thereon wherein said distal end has an outer diameter greater than the proximal end. The venous anchor device is fluidly connected by a graft to form an anastomotic connector.

Claims

1. A venous anchor device comprising:

a tubular main body comprising a metal frame structure defined by a plurality of struts and connectors, said tubular main body including a distal end and a proximal end, said distal end including a plurality of barbs thereon wherein said distal end has an outer diameter greater than the proximal end.

2. The venous anchor device of claim 1 wherein said barbs extend radially outwardly at an acute angle from a longitudinal axis of the tubular main body.

3. The venous anchor device of claim 1 wherein said barbs are configured to lie adjacent a venous vessel wall.

4. The venous anchor device of claim 1 wherein said barbs are configured to penetrate a venous vessel wall to seat said device in a venous passageway.

5. The venous anchor device of claim 1 wherein said venous anchor device is coated with a fluid impermeable material.

6. The venous anchor device of claim 1 wherein said venous anchor device is formed from a shape memory material.

7. The venous anchor device of claim 5 wherein said fluid impermeable material is woven.

8. The venous anchor device of claim 5 wherein said fluid impermeable material is a polymeric material.

9. The venous anchor device of claim 5 wherein said fluid impermeable material is deposited onto said device by electrospinning.

10. The venous anchor device of claim 5 wherein said fluid impermeable material is deposited onto said device by extrusion.

11. The venous anchor device of claim 5 wherein said coating covers the entirety of said device.

12. The venous anchor device of claim 5 wherein said coating covers the proximal end, a mid-portion and the distal end such that said plurality of barbs remain uncoated.

13. The venous anchor device of claim 1 further comprising a graft material fluidly coupled to said venous anchor device.

14. The venous anchor device of claim 13 wherein an outer diameter of the proximal end of said venous anchor device is greater than an inner diameter of the graft material.

15. The venous anchor device of claim 14 wherein the proximal end of said venous anchor device forms a compression fit with the graft material.

16. The venous anchor device of claim 1 wherein said tubular main body is flexible.
