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. Upon actuation of the fixation device, the fasteners puncture the tubular structure. The fasteners are received by the receiving portions such that the tubular structure is coupled with the ring.
1. An anastomotic coupler comprising:
a ring;
a cartridge including a body and a plurality of fasteners extending from the body at an angle,
wherein the ring is aligned with the cartridge in that the cartridge is disposed within a lumen of a tubular structure and the ring is positioned external of the tubular structure,
wherein the plurality of fasteners are operable to puncture the tubular structure,
wherein the plurality of fasteners are operable to be received by the ring such that the tubular structure is coupled with the ring.
2. The anastomotic coupler of claim 1 , wherein a 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 1 , wherein upon actuation of a fixation device, the fasteners rotate in relation to the tubular structure.
4. The anastomotic coupler of claim 1 , wherein a sheath is provided to cover the fasteners until the cartridge is positioned inside the tubular structure.
5. The anastomotic coupler of claim 4 , wherein the sheath is removed to uncover the fasteners after the cartridge is positioned inside the tubular structure.
6. The anastomotic coupler of claim 1 , wherein upon actuation of a fixation device, the body of the cartridge expands radially against the tubular structure.
7. The anastomotic coupler of claim 1 , wherein the angle of the fasteners in relation to the body is greater than 0 degrees and less than 90 degrees.
8. The anastomotic coupler of claim 1 , wherein one row of fasteners is provided on the cartridge.
9. The anastomotic coupler of claim 1 , wherein two rows of fasteners are provided on the cartridge.
10. The anastomotic coupler of claim 1 , wherein the ring includes a receiving portion, the receiving portion includes one or more gaskets.
11. The anastomotic coupler of claim 10 , wherein at least one of the fasteners are operable to directly puncture the one or more gaskets upon puncturing the tubular structure.
12. The anastomotic coupler of claim 11 , wherein the at least one of the fasteners are compressed between two gaskets of the one or more gaskets.
