Abstract

A flexible suture for coupling tissue includes a first suture portion extending to a first end and a second suture portion extending to a second end. A plurality of braided strands form the first and second suture portions. An identifier characteristic is formed into the plurality of braided strands. The identifier characteristic extends from the first end of the first suture portion to the second end of the second suture portion, and the identifier characteristic distinguishes the first suture portion from the second suture portion.

First claim

What is claimed is:

1. A flexible suture, comprising:
an elongate member comprising a plurality of braided strands, wherein the elongate member comprises a first suture portion extending from a midpoint to a first end and a second suture portion extending from the midpoint to an opposed second end, and wherein the plurality of braided strands comprises:
a plurality of suture strands, wherein each of the plurality of suture strands comprises a first material having a first appearance, and
a tracer strand comprising a second material having a second appearance comprising at least one identifier characteristic, wherein the tracer strand extends continuously from the first end to the second end of the elongate member, wherein the identifier characteristic contrasts the tracer strand from the plurality of suture strands; and
wherein the plurality of braided strands have a first braid configuration over the first suture portion where the tracer strand has a first number of picks per inch over the first suture portion, wherein the plurality of braided strands have a second braid configuration over the second suture portion where the tracer strand has a second number of picks per inch over the second suture portion that is different from the first number of picks per inch, and wherein the first suture portion and the second suture portion are visually distinct.

2. The flexible suture of claim 1 , wherein the identifier characteristic of the tracer strand comprises a contrast color that is visually distinct from the first appearance of the plurality of suture strands.

3. The flexible suture of claim 1 , wherein at least one of the first braid configuration and the second braid configuration comprise a hollow core braid.

4. The flexible suture of claim 3 , wherein the hollow-core braid comprises 16 strands.

5. The flexible suture of claim 1 , wherein the tracer strand comprises a plurality of tracer strands.

6. A flexible suture, comprising:
a first suture section extending from a first end to a second end thereof, wherein the first suture section comprises a first plurality of braided strands, wherein the first plurality of braided strands comprises a first plurality of suture strands and a first tracer strand, wherein the first tracer strand extends continuously from the first end to the second end, wherein each of the first plurality of suture strands comprises a first material having a first appearance, wherein the first tracer strand comprises a second material having an identifier characteristic that contrasts the first tracer strand from the first plurality of suture strands, and wherein the first plurality of braided strands has a first braided configuration where the first tracer strand has a first number of picks per inch;
a second suture section extending from a third end to a fourth end thereof, wherein the second suture section comprises a second plurality of braided strands, wherein the second plurality of braided strands comprises a second plurality of suture strands and a second tracer strand, wherein the second tracer strand extends continuously from the third end to the fourth end, wherein each of the second plurality of suture strands comprises the first material, wherein the second tracer strand comprises the second material, and wherein the second plurality of braided strands has a second braided configuration where the second tracer strand has a second number of picks per inch that is different from the first number of picks per inch of the first tracer strand of the first plurality of braided strands; and
a coupler coupling the first suture section to the second suture section;
wherein the first suture section and the second suture section are visually distinct.

7. A flexible suture, comprising:
an elongate member comprising a plurality of braided strands, wherein the elongate member comprises a first suture portion extending from a midpoint to a first end and a second suture portion extending from the midpoint to an opposed second end, and wherein the plurality of braided strands comprises:
a plurality of suture strands, wherein each of the plurality of suture strands comprises a first material having a first appearance, and
a tracer strand comprising a second material having a second appearance comprising at least one identifier characteristic, wherein the tracer strand extends continuously from the first end to the second end of the elongate member, wherein the identifier characteristic contrasts the tracer strand from the plurality of suture strands; and
wherein the plurality of braided strands have a first braid configuration over the first suture portion where the tracer strand has a first number of picks per inch over the first suture portion, wherein the plurality of braided strands have a second braid configuration over the second suture portion where the tracer strand has a second number of picks per inch over the second suture portion that is different from the first number of picker per inch, and wherein the first suture portion and the second suture portion are visually distinct; and

an anchor comprising a thread on a distal portion thereof;
wherein the elongate member is coupleable to the anchor.

8. The flexible suture of claim 7 , wherein the identifier characteristic of the tracer strand comprises a contrast color that is visually distinct from the first appearance of the plurality of suture strands.

9. The flexible suture of claim 7 , wherein at least one of the first braid configuration and the second braid configuration comprise a hollow-core braid.

10. The flexible suture of claim 9 , wherein the hollow-core braid comprises 16 strands.

11. The flexible suture of claim 7 , wherein the tracer strand comprises a plurality of tracer strands.
