Exemplary embodiments are directed to providing a method of preparing an anatomical vessel contained within a tissue bundle for ligation, including positioning a cannula (104) adjacent to the tissue bundle, wherein the positioning is non-penetrating, the cannula (104) including a first extendable member (120), a second extendable member (122), a Doppler wand (140), and a distal end, transmitting ultrasound signals toward the vessel through the tissue bundle with the Doppler wand (140), receiving ultrasound signals reflected by the vessel through the tissue bundle with the Doppler wand (140), invaginating the tissue bundle with the first extendable member (120) on a first side of the tissue bundle, invaginating the tissue bundle with the second extendable member on a second side of the bundle opposite the first side, and interpenetrating a length of ligation material between the first and second extendable members (120, 122) on a side of the vessel opposite the cannula distal end.
L'invention concerne des formes de réalisation exemplaires visant à procurer un procédé de préparation d'une structure anatomique contenue dans un faisceau de tissus en vue d'une ligature. Ce procédé consiste à positionner une canule (104) à proximité du faisceau de tissus, ce positionnement étant non pénétrant, et cette canule (104) comprenant une premier élément (120) extensible, un second élément (122) extensible, une tige (140) Doppler, et une extrémité distale, à émettre des signaux ultrasonores vers la structure à travers le faisceau de tissus avec la tige (140) Doppler, à recevoir des signaux ultrasonores provenant de la structure à travers le faisceau de tissus avec la tige (140) Doppler, à invaginer le faisceau de tissus au moyen du premier élément (120) extensible sur le premier côté du faisceau de tissus, à invaginer le faisceau de tissus au moyen du second élément (122) extensible sur le second côté du faisceau à l'opposé du premier côté, et à interpénétrer une longueur de matériau de ligature entre les premier et second éléments (120, 122) extensibles d'un côté de la structure à l'opposé de l'extrémité distale de la canule.
