A method and a staple cartridge for ligating a hollow organic tubular structure by means of surgical staples. The organic tubular structure is loosely confined within an area which is variable in accordance with the position of the ligating surgical staples. The staples, being U-shaped are moved toward the organic tubular structure, thereby decreasing the confining area, until the arms of the staples begin to bend around the structure. The staple arms are bent until they encircle the tubular structure and contact one another; then the staples are further deformed, by acting on the surfaces remote from the contacting arms, until the tubular structure is completely sealed. During the staple-bending operation, the periphery of the tubular structure is positively controlled by the ligating cartridge, thereby ensuring the integrity of the structure.
