Abstract

A system includes a knot tying device for tying a filament in a knot around an article and a filament delivery device from which is drawn the filament. The filament delivery device may be in the form of a cartridge having a housing sized and arranged to be releasably attached to the knot tying device where the housing has an opening through which pre-cut or loosely coupled lengths of the filament can be drawn. The knot tying device includes a shuttle attachable to the filament where the shuttle is caused to be moved during a knot tying process around an article to be tied and a device for at least pulling the filament away from the article at appropriate times during the knot tying process.
