Anastomotic coupler
An anastomotic coupler is provided. A ring can include a plurality of receiving portions. A fixation device includes a cartridge. The cartridge includes a plurality of fasteners. The ring is aligned with the cartridge such that the receiving portions are aligned with the fasteners. Upon actuation of the fixation device, the fasteners puncture the tubular structure and are received by the receiving portions such that the tubular structure is coupled with the ring.
1. An anastomotic coupler comprising:
a ring including a plurality of receiving portions, the ring operable to be disposed external to a tubular structure;
a cartridge operable to be disposed within a lumen of the tubular structure, the cartridge including a plurality of fasteners,
wherein the ring is aligned with the cartridge such that the plurality of receiving portions are aligned with the plurality of fasteners,
wherein the plurality of fasteners are operable to puncture the tubular structure radially outward from the lumen and are received by the plurality of receiving portions of the ring such that the tubular structure is coupled with the ring.
2. The anastomotic coupler of claim 1 , further comprising a fixation device, wherein the fixation device includes a stop, the stop extending radially from a 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 a fixation device, the drivers activate to push the corresponding fasteners 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.
