Abstract

An apparatus and system for forming a compression anastomosis. The apparatus includes an anastomotic device. An anastomotic portion of the anastomotic device includes a first end and a second end. The anastomotic portion is formed of a ferrous, magnetic, or paramagnetic material. At least one flexible portion protrudes from the first end of the anastomotic portion. The at least one flexible portion includes an articulation node located at a predetermined distance from the first end of the anastomotic portion. The articulation node enables the at least one flexible portion to move relative to the anastomotic portion. The system further includes a magnet having a first end and a second end. The magnet is adapted to magnetically couple to the anastomotic portion of the anastomotic device and to compress tissue between the magnet and the anastomotic device. The compressive force on the tissue is sufficient to create a compression anastomosis through the tissue.

Claims

1. An apparatus, comprising:

an anastomotic portion comprising a first end and a second end; and

at least one flexible portion protruding from the first end of the anastomotic portion, the at least one flexible portion comprising a first articulation node located at a predetermined distance from the first end of the anastomotic portion, wherein the articulation node enables the at least one flexible portion to move relative to the anastomotic portion.

2. The apparatus of claim 1, wherein the anastomotic portion is formed of any one of a ferrous, magnetic, and paramagnetic material.

3. The apparatus of claim 2, wherein the anastomotic portion is formed of any one of quaternary Iron, Neodymium, Iron, Boron, and Samarium comprises.

4. The apparatus of claim 2, wherein the anastomotic portion is formed of any one of quaternary Iron, Neodymium, Iron, Boron, and Samarium particles incorporated in a rubber or plastic material.

5. The apparatus of claim 1, further comprising at least one magnet attached to the anastomotic portion.

6. The apparatus of claim 1, wherein the anastomotic portion comprises a lumen extending through a longitudinal portion thereof.

7. The apparatus of claim 6, wherein the at least one flexible portion comprises a lumen extending through a longitudinal portion thereof, and wherein the anastomotic portion and the at least one flexible portion are in fluid communication by way of the lumen.

8. The apparatus of claim 1, wherein the anastomotic portion and the at least one flexible portion comprise a longitudinal tubular structure suitable for positioning within a hollow viscus and draining fluid therefrom.

9. The apparatus of claim 1, wherein the anastomotic portion and the at least one flexible portion are formed of solid materials.

10. The apparatus of claim 1, wherein the at least one flexible portion is formed of a polymeric material.

11. The apparatus of claim 1, wherein the at least one flexible portion comprises a tapered portion.

12. The apparatus of claim 1, comprising

a second flexible portion protruding from the second end of the anastomotic portion, the second flexible portion comprising a second articulation node located at a predetermined distance from the second end of anastomotic portion, wherein the articulation node enables the second flexible portion to move relative to the anastomotic portion.

13. A system for forming a compression anastomosis, the system comprising:

an anastomotic device comprising an anastomotic portion comprising a first end and a second end, wherein the anastomotic portion is formed of a ferrous, magnetic, or paramagnetic material; and

at least one flexible portion protruding from the first end of the anastomotic portion, the at least one flexible portion comprising an articulation node located at a predetermined distance from the first end of the anastomotic portion, wherein the articulation node enables the at least one flexible portion to move relative to the anastomotic portion; and

a magnet having a first end and a second end, wherein the magnet is adapted to magnetically couple to the anastomotic portion of the anastomotic device and to compress tissue between the magnet and the anastomotic device, wherein the compressive force on the tissue is sufficient to create an anastomosis through the tissue.

14. The system of claim 13, wherein the at least one flexible portion is adapted to move relative to the anastomotic portion when the magnet magnetically couples the anastomotic portion and the anastomosis is formed.

15. The system of claim 13, wherein the magnet comprises a central lumen configured to slideably receive a pusher.

16. The system of claim 13, wherein the magnet comprises a tube attached thereto, wherein the tube is configured to receive a guide-wire.

17. The system of claim 13, wherein the magnet comprises radii formed at the first and second ends.

18. The system of claim 13, wherein the magnet comprises a coating.

19. The system of claim 18, wherein the coating comprises Chromium.

20. A method of forming an anastomosis, comprising:

positioning an anastomotic device in a first hollow viscus, the anastomotic device comprising an anastomotic portion comprising a first end and a second end, wherein the anastomotic portion is formed of a ferrous, magnetic, or paramagnetic material; and

at least one flexible portion protruding from the first end of the anastomotic portion, the at least one flexible portion comprising an articulation node located at a predetermined distance from the first end of the anastomotic portion, wherein the articulation node enables the at least one flexible portion to move relative to the anastomotic portion; and

positioning a magnet within a second hollow viscus, the magnet having a first end and a second end, wherein the magnet is adapted to magnetically couple to the anastomotic portion of the anastomotic device and to compress tissue of the first and second hollow viscus between the magnet and the anastomotic device, wherein the compressive force on the tissue is sufficient to create a compression anastomosis between the first and second hollow viscus.
