A surgical fastener system for fixing a mesh prosthesis to body tissue for the laparoscopic repair of inguinal herniation or for fixing body tissue to body tissue. A unidirectional dart fastener is utilized where the dart fastener is composed of a shaft member and an anchor member extending angularly from the tip of the shaft. The anchor member is resiliently collapsable radially to the shaft and biased in an open position which permits the dart to be captively held unidirectionally in the body fascia. A dart fixation tool carries the dart fastener in a cartridge which has a series of cylindrical chambers spaced radially adjacent to the periphery of the cartridge and the dart is ejected into the body tissue by a setting rod which is responsive to an external force to thrust the rod through the chamber. The setting rod is thereafter retracted from the chamber and the cartridge is rotated by the surgeon to bring another succeeding chamber into alignment with the setting rod.
