A method of affixing a barb to a suture, the method comprising:
- providing a barb supply assembly including at least a first barb having a retaining portion including at least one leg member having at least one anchor member;
- aligning a suture with the retaining portion of the first barb;
- and
- activating a pusher assembly to approximate at least one of the suture and the first barb towards the other of the first barb and the suture such that the retaining portion of the first barb engages the suture.
A method of affixing a barb to a suture, the method comprising:
- providing a barb supply assembly including at least a first barb having a retaining portion including at least one leg member having at least one anchor member;
- aligning a suture with the retaining portion of the first barb by raising or lowering at least one of the suture or the barb supply mechanism;
- and
- approximating at least one of the suture and the first barb towards the other of the first barb and the suture such that the retaining portion of the first barb engages the suture.
A method of affixing a barb to a suture, the method comprising:
- providing a barb supply assembly including a plurality of barbs supported on a carrier strip, wherein the plurality of barbs are longitudinal spaced from one another along the carrier strip;
- aligning a suture with a first barb of the plurality of barbs;
- and
- approximating at least one of the suture and the first barb towards the other of the first barb and the suture such that the first barb engages the suture.
