A tissue fastening device comprising (a) a fastener member having a pair of legs extending from the same side of a connecting cross piece, said fastener member adapted to be placed on one side of the tissue to be joined with the legs penetrating the tissue, said fastener member being an oriented crystalline polymeric material, whereby the fastener member has sufficient inherent strength and stiffness so said legs can penetrate the tissue to be fastened, and (b) a receiver member to secure said fastener member in place. The fastener member is formed by forming an oriented polymeric filament into the configuration of the fastener member, and annealing the filament while in such configuration while it is being restrained so as to prevent shrinkage.

Surgical fastening device and method for manufacture

Sterile surgical monofilament sutures are disclosed. The sutures are made from ethylene-propylene copolymers, and have improved compliance, compared with polypropylene homopolymer sutures.

Ethylene-propylene copolymer sutures

Surgical filaments are made from a copolymer of vinylidene fluoride and hexafluoropropylene.
