Anastomotic coupler
An anastomotic coupler is provided. A ring can include a receiving portion. 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. A cartridge for an anastomotic coupler, the cartridge comprising:
a body operable to be received in a tubular structure extending along a longitudinal axis, the body having an outer radial surface and an axial surface, the radial surface operable to abut against and be substantially parallel to a wall of the tubular structure, the axial surface extending at an angle from the outer radial surface; and
one or more fasteners extending from the axial surface at an angle from the longitudinal axis, the one or more fasteners operable to puncture the wall of the tubular structure, at least a portion of each of the one or more fasteners operable to be received by a receiving portion of a ring such that the tubular structure is coupled with the ring.
2. The cartridge of claim 1 , wherein the one or more fasteners each have an end that is linear, curved, bent, and/or hooked.
3. The cartridge of claim 1 , further including a sheath operable to receive the one or more fasteners such that the one or more fasteners are covered until the cartridge is positioned inside the tubular structure.
4. The cartridge of claim 3 , wherein when the one or more fasteners are received in the sheath, the one or more fasteners extend from the axial surface substantially parallel to the longitudinal axis.
5. The cartridge of claim 3 , wherein when the sheath is removed to expose the one or more fasteners, the one or more fasteners expand radially outward to be at an angle from the longitudinal axis.
6. The cartridge of claim 1 , wherein the body has a diameter substantially the same as a diameter of the lumen of the tubular structure so that the outer radial surface abuts against the wall of the tubular structure to maintain the shape of the tubular structure.
7. The cartridge of claim 1 , wherein the body forms a body lumen to permit fluid to flow across the body.
8. An anastomotic coupler comprising:
a ring operable to receive a tubular structure extending along a longitudinal axis, the ring including a receiving portion; and
a cartridge operable to be received in the tubular structure, the cartridge including:
a body operable to be received in the tubular structure, the body having an outer radial surface and an axial surface, the radial surface operable to abut against and be substantially parallel to a wall of the tubular structure, the axial surface extending at an angle from the outer radial surface; and
one or more fasteners extending from the axial surface at an angle from the longitudinal axis, the one or more fasteners operable to puncture the wall of the tubular structure, at least a portion of each of the one or more fasteners operable to be received by the receiving portion of the ring such that the tubular structure is coupled with the ring.
9. The anastomotic coupler of claim 8 , wherein the one or more fasteners each have an end that is linear, curved, bent, and/or hooked.
10. The anastomotic coupler of claim 8 , further including a sheath operable to receive the one or more fasteners such that the one or more fasteners are covered until the cartridge is positioned inside the tubular structure.
11. The anastomotic coupler of claim 10 , wherein when the one or more fasteners are received in the sheath, the one or more fasteners extend from the axial surface substantially parallel to the longitudinal axis.
12. The anastomotic coupler of claim 10 , wherein when the sheath is removed to uncover the one or more fasteners, the one or more fasteners expand radially outward to be at an angle from the longitudinal axis.
13. The anastomotic coupler of claim 10 , further comprising a fixation device operable to position the cartridge in the tubular structure, wherein upon actuation of the fixation device, the sheath is removed.
14. The anastomotic coupler of claim 8 , wherein the body has a diameter substantially the same as a diameter of the lumen of the tubular structure so that the outer radial surface abuts against the wall of the tubular structure to maintain the shape of the tubular structure.
15. The anastomotic coupler of claim 8 , wherein the body forms a body lumen to permit fluid to flow across the body.
16. A system comprising:
a first ring including a receiving portion;
a second ring including a receiving portion;
a first cartridge operable to be received in a first tubular structure, the first cartridge including:
a body operable to be received in the first tubular structure, the body having an outer radial surface and an axial surface, the radial surface operable to abut against and be substantially parallel to a wall of the first tubular structure, the axial surface extending at an angle from the outer radial surface; and
one or more fasteners extending from the axial surface at an angle from the longitudinal axis, the one or more fasteners operable to puncture the wall of the first tubular structure, at least a portion of each of the one or more fasteners operable to be received by the receiving portion of the first ring such that the first tubular structure is coupled with the first ring;
a second cartridge operable to be received in a second tubular structure, the second cartridge including:
a body operable to be received in the second tubular structure, the body having an outer radial surface and an axial surface, the radial surface operable to abut against and be substantially parallel to a wall of the second tubular structure, the axial surface extending at an angle from the outer radial surface; and
one or more fasteners extending from the axial surface at an angle from the longitudinal axis, the one or more fasteners operable to puncture the wall of the second tubular structure, at least a portion of each of the one or more fasteners operable to be received by the receiving portion of the second ring such that 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 a lumen of the first tubular structure and a lumen of the second tubular structure are aligned in fluid communication with one another.
17. The system of claim 16 , wherein the one or more fasteners of the first cartridge extends through the receiving portion of the first ring and is received in the receiving portion of the second ring such that the first ring and the second ring are coupled to one another.
18. The system of claim 17 , wherein the one or more fasteners of the second cartridge extends through the receiving portion of the second ring and is received in the receiving portion of the first ring such that the first ring and the second ring are coupled to one another.
19. The system of claim 16 , wherein the first ring and the second ring create a seal to prevent fluid leakage.
