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.
L'invention concerne des pinces chirurgicales (100) destinées à stopper le flux d'un fluide dans une lumière corporelle, et pourvues d'un cylindre externe (102) comprenant une paroi latérale annulaire (106) présentant au moins une paire de rainures radiales (110), et d'un cylindre interne (104) couplé de manière rotative et concentrique au cylindre externe (102). Le cylindre interne (104) possède une paroi latérale annulaire (118) comprenant une rainure radiale (122) correspondant à chaque rainure radiale (110) du cylindre externe. La pince chirurgicale (100) possède une position ouverte dans laquelle les rainures radiales (110) du cylindre externe (102) sont alignées de manière radiale avec les rainures radiales correspondantes (122) du cylindre interne (104), et une position fermée dans laquelle les rainures radiales (110) du cylindre externe (102) ne sont pas alignées de manière radiale avec les rainures radiales correspondantes (122) du cylindre interne (104), rétrécissant ainsi la lumière corporelle au niveau de deux emplacements sur sa longueur. L'invention concerne également un applicateur (200, 500, 600) permettant de mettre en place les pinces chirurgicales.
