Abstract
A method of suturing includes: (1) wrapping a first segment of a suture through a traction loop; (2) pulling the traction loop and the first segment through an opening in a suture lock; (3) continuing to pull the traction loop such that a second segment of the suture extends through the opening, wherein the second segment has a greater denier than the first segment such that the second segment more nearly fills an entire dimension of the opening than the first segment; and (4) locking the suture in place with the second segment in the opening.

1-20. (canceled)
A multi-denier suture for repair of soft tissue, comprising:
- a tubular braid structure comprising strands and configured to be placed against soft tissue to suture the soft tissue, the tubular braid structure extending along a longitudinal axis and having a length, a first end, distal and proximal axial segments, and a middle axial segment comprising a transition zone positioned between the distal and proximal axial segments;
- wherein the distal segment extends axially from the first end to the middle axial segment and has a first denier, the middle axial segment has a second denier greater than the first denier;
- and the proximal segment extends axially from the middle axial segment and has a third denier, wherein the third denier is greater than the second denier;
- and
- wherein (i) a first plurality of the strands extends the entire length of the tubular braid structure, (ii) the proximal axial segment comprises a second plurality of the strands braided together with a first portion of the first plurality of the strands, and (iii) respective distal ends of the second plurality of the strands terminate at the transition zone.
A multi-denier suture for repair of soft tissue, comprising:
- a continuous braided tubular structure comprising a first plurality of strands braided together and extending along a longitudinal axis, the continuous braided tubular structure having a first end, a first axial length, proximal and distal segments, and a first transition zone between the proximal and distal segments;
- and
- an inner tubular structure extending along the longitudinal axis, the inner tubular structure having proximal and distal ends and a second axial length, the second axial length being shorter than the first axial length;
- and
- wherein:
- (i) the proximal segment comprises the inner tubular structure radially enclosed within the continuous braided tubular structure;
- (ii) the distal segment extends distally beyond the distal end of the inner tubular structure and comprises first and second sections with a second transition zone positioned therebetween;
- and
- (iii) the first section has a first denier, the second section has a second denier, the proximal segment has a third denier, and the third is larger than the first denier.
