Abstract
A high strength abrasion resistant surgical suture material with improved tie down characteristics and tissue compliance includes poly(p-phenylene-2,6-benzobisoxazole) (PBO). The suture features a multifilament jacket formed of braided strands of PBO, optionally with fibers of polyester, silk, nylon or aramid strands as an enhancer. In one embodiment, the braided jacket surrounds a core formed of twisted strands of PBO. The suture has exceptional strength, is ideally suited for most orthopedic procedures, and can be attached to a suture anchor or a curved needle.
