  • Patent number: 5271494
    Abstract: A suture material pack for surgical suture material comprises. The pack includes a folding card (10) with a base plate (11) and a pair of cover plates (13, 14) adjoining the same in the longitudinal direction. Projecting to one side from the base plate (11), there is a first holding plate (22) over which a second holding plate (27) may be folded. The holding plates enclose the suture material (35) and they are shorter than the suture material loop. During the placing of the suture material and the closing of the holding plates, the suture material loop can be held at the ends. The cover plates (13) and (14) are then folded onto the base plate and the holding plate folded thereon so that the suture material is protected. The folding card (10) is welded into a foil sheath that is torn open to take out the filament. In doing so, a flap (14a) provided at the second cover plate (14) is torn off so as to expose the filament end.
