Anastomotic coupler

1. An anastomotic coupler comprising:

a ring forming an aperture operable to receive a tubular structure, the ring including a plurality of receiving portions;

a fixation device including a housing and a cartridge, the cartridge including a plurality of fasteners, the housing operable to receive the tubular structure such that the cartridge is inserted into a lumen of the tubular structure,

wherein the ring is aligned with the cartridge such that the plurality of receiving portions are aligned with the plurality of fasteners,

wherein upon actuation of the fixation device, the plurality of fasteners puncture the tubular structure radially outward from the lumen and are received by the receiving portions such that the tubular structure is coupled with the ring.

2. The anastomotic coupler of claim 1 , wherein the fixation device includes a stop, the stop extending radially from the housing such that a free end of the tubular structure abuts the stop.

3. The anastomotic coupler of claim 2 , wherein the stop includes a plurality of alignment components corresponding with alignment components of the ring, wherein when the ring is aligned, the alignment components of the stop are aligned with the alignment components of the ring.

4. The anastomotic coupler of claim 1 , wherein the cartridge includes a plurality of drivers corresponding with the plurality of fasteners, wherein upon actuation of the fixation device, the drivers activate to push the corresponding fasteners radially outward from the cartridge.

5. The anastomotic coupler of claim 4 , wherein the fixation device includes a pusher rod, wherein upon actuation of the fixation device, the pusher rod translates along a longitudinal axis to activate the drivers.

6. The anastomotic coupler of claim 5 , wherein the pusher rod is tapered from a front portion with a smaller diameter to a rear portion with a larger diameter.

7. The anastomotic coupler of claim 1 , wherein the plurality of fasteners include tacks, staples, pins, adhesive, internal ring, internal mesh, wire, clamp, coil, and/or suture.

8. A system comprising:

a first ring forming an aperture operable to receive a first tubular structure, the first ring including a plurality of receiving portions;

a second ring forming an aperture operable to receive a second tubular structure, the second ring including a plurality of receiving portions;

a fixation device including a housing and a cartridge, the cartridge including a plurality of fasteners, the housing operable to receive the first and/or second tubular structure such that the cartridge is inserted into a lumen of the corresponding first and/or second tubular structure,

wherein the first and/or second ring is aligned with the cartridge such that the corresponding plurality of receiving portions are aligned with the plurality of fasteners,

wherein upon actuation of the fixation device, the plurality of fasteners puncture the first and/or second tubular structure radially outward from the lumen and are received by the receiving portions such that the first tubular structure is coupled with the first ring and the second tubular structure is coupled with the second ring,

wherein the first ring and the second ring are coupled with one another and the first tubular structure and the second tubular structure are joined such that the lumen of the first tubular structure and the lumen of the second tubular structure are aligned in fluid communication with one another.

9. The system of claim 8 , wherein the first ring and the second ring create a seal to prevent fluid leakage.

10. The system of claim 8 , wherein the cartridge includes a plurality of drivers corresponding with the plurality of fasteners, wherein upon actuation of the fixation device, the drivers activate to push the corresponding fasteners radially outward from the cartridge.

11. The system of claim 10 , wherein the fixation device includes a pusher rod, wherein upon actuation of the fixation device, the pusher rod translates along a longitudinal axis to activate the drivers.

12. The anastomotic coupler of claim 11 , wherein the pusher rod is tapered from a front portion with a smaller diameter to a rear portion with a larger diameter.

13. The system of claim 8 , wherein the plurality of fasteners include tacks, staples, pins, adhesive, internal ring, internal mesh, wire, clamp, coil, and/or suture.

14. A method comprising:

receiving a tubular structure in an aperture of a ring;

receiving, by a fixation device, the tubular structure such that a cartridge is inserted into a lumen of the tubular structure;

aligning the ring with the cartridge such that a plurality of receiving portions of the ring are aligned with a plurality of fasteners of the cartridge;

actuating the fixation device such that the plurality of fasteners puncture the tubular structure radially outward from the lumen; and

coupling the tubular structure with the ring by the receiving portions receiving the plurality of fasteners.

15. The method of claim 14 , further comprising:

receiving a second tubular structure in an aperture of a second ring;

receiving, by a fixation device, the second tubular structure such that a second cartridge is inserted into a lumen of the second tubular structure;

aligning the second ring with the second cartridge such that a plurality of receiving portions of the second ring are aligned with a plurality of fasteners of the second cartridge;

actuating the fixation device such that the plurality of fasteners puncture the second tubular structure radially outward from the lumen; and

coupling the second tubular structure with the second ring by the receiving portions receiving the plurality of fasteners.

16. The method of claim 15 , further comprising:

aligning the ring with the second ring such that the lumen of the first tubular structure and the lumen of the second tubular structure are aligned in fluid communication with one another; and

coupling the ring with the second ring to join the tubular structure with the second tubular structure.

17. The method of claim 14 , wherein the cartridge includes a plurality of drivers corresponding with the plurality of fasteners, wherein upon actuation of the fixation device, the drivers activate to push the corresponding fasteners radially outward from the cartridge.

18. The method of claim 17 , wherein the fixation device includes a pusher rod; wherein the pusher rod is tapered from a front portion with a smaller diameter to a rear portion with a larger diameter, wherein upon actuation of the fixation device, the pusher rod translates along a longitudinal axis to activate the drivers.
