A system and method for affixing barbs on a suture are provided. In one embodiment, the system includes a suture supply mechanism for selectively retaining a length of suture and a barb supply mechanism for operably engaging a barb supply assembly including at least one barb. At least one of the suture supply mechanism and the barb supply mechanism are configured to approximate towards the other of the barb supply mechanism and suture supply mechanism to engage the at least one barb of the barb supply assembly with the suture of the suture supply assembly. Also provided are a barb for use in forming a barbed suture and a suture including at least one barb.
1. A system for fixing a barb to a suture, the system comprising:
a suture supply mechanism for selectively retaining a length of suture; and
a barb supply mechanism including a pusher assembly for operably engaging at least one barb of a barb supply assembly, wherein at least one of the suture supply mechanism and the barb supply mechanism are configured to engage the at least one barb of the barb supply assembly with the suture of the suture supply assembly.
2. The system of claim 1 , wherein at least one of the suture supply mechanism and the barb supply mechanism are configured to approximate towards the other of the barb supply mechanism and suture supply mechanism.
3. The system of claim 1 , wherein the suture supply mechanism includes an anvil assembly for supporting a length of suture thereagainst.
4. The system of claim 3 , wherein the anvil assembly includes an anvil for supporting the length of suture.
5. The system of claim 3 , wherein the suture supply mechanism is configured to advance a suture relative to the anvil assembly.
6. The system of claim 5 , wherein the suture supply mechanism includes a suture supply assembly for supplying the length of a suture and a suture uptake assembly for taking up the length of the suture.
7. The system of claim 1 , wherein the pusher assembly includes a pusher for engaging the at least one barb of the barb supply assembly.
8. The system of claim 1 , wherein the barb supply mechanism is configured to advance the barb supply assembly relative to the pusher assembly.
9. The system of claim 1 , wherein the barb supply mechanism includes a sprocket for advancing the barb supply assembly relative to the pusher assembly.
10. The system of claim 1 , further including a barb supply assembly.
11. The system of claim 10 , wherein at least one barb of the barb supply assembly includes a base.
12. The system of claim 11 , wherein the at least one barb includes a barb portion extending from the base in a first direction.
13. The system of claim 12 , wherein the at least one barb includes a pair of anchor members extending from the base in a second direction.
14. The system of claim 1 , further including a length of suture.
