ABSTRACT:
Surgical fasteners (100) are disclosed for terminating flow of fluid through a body lumen, including an outer barrel (102) having an annular side wall (106) having at least a pair of radial slots (110) formed therein, and an inner barrel (104) rotatably and concentrically coupled within the outer barrel (102). The inner barrel (104) has an annular side wall (118) including a radial slot (122) formed therein corresponding to each radial slot (110) formed in the outer barrel. The surgical fastener (100) has an open position in which the radial slots (110) of the outer barrel (102) are radially aligned with the corresponding radial slots (122) of the inner barrel (104) and a closed position in which the radial slots (110) of the outer barrel (102) are out of radial alignment with the corresponding radial slots (122) of the inner barrel (104) and constrict the body lumen at two locations along the length thereof. An applier (200, 500, 600) is provided for applying the surgical fasteners.
