Abstract

A high strength abrasion resistant surgical suture material with improved tie down characteristics and tissue compliance with braided yarns formed of ether-ketone variant. The suture features a multifilament jacket formed of braided yarns of ether-ketone variant, optionally braided with yarns of polyester, silk, nylon, ultrahigh molecular weight polyethylene or aramid fibers. The braided jacket surrounds a core formed of twisted yarns of ether-ketone variant or ultrahigh molecular weight polyethylene. The suture has exceptional strength, is ideally suited for most orthopedic procedures, and can be attached to a suture anchor or a curved needle.

Claims

1. A suture strand comprising a plurality of braided yarns formed of a polyether-ketone variant.

2. The suture strand of claim 1, further comprising a core comprising yarns of polyether-ketone variant surrounded by a jacket comprising yarns of polyether-ketone variant.

3. The suture strand of claim 1, wherein the yarns of polyether-ketone variant comprises at least 31% of the yarns in the suture strand.

4. The suture strand of claim 1, wherein the core comprises about 12.6% or greater of the total amount of yarns in the suture strand.

5. The suture strand of claim 2, wherein the core comprises braided yarns of polyether-ketone variant.

6. The suture strand of claim 1, wherein the polyether-ketone variant is selected from a group consisting of polyetherketone, polyetherketoneketone, and polyetherether-ketone.

7. The suture strand of claim 1, further comprising a coating disposed on the jacket, the coating being selected from the group consisting of wax, silicone, silicone rubbers, PTFE, PBA, and ethyl cellulose.

8. The suture strand of claim 1, wherein the core is formed of at least three yarns of the polyether-ketone variant twisted at three to six twists per inch.

9. The suture strand of claim 1, wherein the jacket is formed of yarns of the polyether-ketone variant braided with yarns of polyester.

10. The suture strand of claim 1, wherein the jacket is formed of yarns of the polyether-ketone variant braided with yarns of ultrahigh molecular weight polyethylene.

11. The suture strand of claim 1, wherein further comprising a core formed of twisted yarns of the polyether-ketone variant.

12. The suture strand of claim 1, wherein further comprising a core formed of twisted yarns of ultrahigh molecular weight polyethylene.

13. A suture assembly comprising:

a suture, the suture having a longitudinal length and a multifilament jacket comprising a plurality of braided yarns of polyether-ketone variant; and

a suture anchor, wherein the suture is threaded through an eyelet of the suture anchor.

14. A method of using a suture strand, comprising the steps of:

cutting a bulk length of multifilament suture material to make a plurality of suture yarns, the multifilament suture material comprising a plurality of braided yarns of polyether-ketone variant; and

attaching one of the plurality of suture yarns to a suture anchor by threading through an eyelet of the suture anchor.
