Abstract

A high strength surgical suture formed of ultrahigh molecular weight polyethylene (UHMWPE) yarns, the suture being coated with native or denatured collagen. The braided jacket surrounds a core formed of twisted yarns of 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 comprising a jacket comprising a plurality of braided yarns formed of ultrahigh molecular weight polyethylene, the suture being coated with collagen.

2. The suture of claim 1, further comprising a core comprising yarns of ultrahigh molecular weight polyethylene surrounded by the jacket.

3. The suture of claim 2, wherein the yarns of ultrahigh molecular weight polyethylene comprise at least 40% of the yarns in the suture.

4. The suture of claim 2, wherein the core comprises about 18% or greater of the total amount of yarns in the suture.

5. The suture of claim 2, wherein the jacket comprises yarns of the ultrahigh molecular weight polyethylene braided with yarns of polyester.

6. The suture of claim 2, wherein the jacket further comprises trace yarns for suture identification.

7. The suture of claim 2, wherein the core is formed of at least three yarns of the ultrahigh molecular weight polyethylene twisted at three to six twists per inch.

8. The suture of claim 2, wherein the jacket comprises yarns of ultrahigh molecular weight polyethylene braided with yarns of a bioabsorbable material comprising PLLA.

9. The suture of claim 2, wherein the jacket comprises at least eight yarns of the ultrahigh molecular weight polyethylene braided with six yarns of polyester and two yarns of nylon.

10. A suture assembly comprising:

a suture, the suture having a longitudinal length and a multifilament jacket comprising a plurality of braided yarns of ultrahigh molecular weight polyethylene, the suture being coated with collagen; and

a suture anchor, wherein the suture is attached to the suture anchor.

11. A suture assembly comprising:

a suture, the suture having a longitudinal length and a multifilament jacket comprising a plurality of braided yarns of ultrahigh molecular weight polyethylene, the suture being coated with collagen; and

a needle, wherein the suture is attached to the needle.
