Abstract
A hybrid monofilament/braided surgical suture that combines a monofilament with a braided construction. The hybrid surgical suture may be formed by braiding yarns of high tenacity fibers tightly over a core in the form of a monofilament yarn. The monofilament may be any type of material, for example, a nylon, silk, polyester, polyethylene or polypropylene filament, among many others. The stiffness properties of the hybrid surgical suture allow the suture to be pushed through small and very small diameter tubes and cannulations (such as Lasso instruments, for example) yet fix securely with existing fixation devices (such as knotless suture anchors like PushLock® anchors).
Claims18
A surgical suture, consisting of:
- a monofilament core having a longitudinal axis;
- and
- a braided sheath surrounding at least part of the monofilament core and extending along the longitudinal axis of the monofilament core.
A suture construct, comprising:
- a suture strand having a first end which is a free end and a second end which is a closed loop;
- and
- a monofilament core incorporated within the closed loop so that the suture strand completely covers the monofilament core.
A suture for surgical repairs consisting essentially of a core of a nylon monofilament and a jacket comprising a plurality of braided multi-filament yarns formed of ultrahigh molecular weight polyethylene.
