Surgical method and apparatus (12) for resectioning tissue (210), preferably lumenal tissue (208), with a remaining portion of an organ being anastomosed with staples or other fastening means, preferably endolumenally. The apparatus may be inserted via a naturally occurring body orifice or a surgical incision and then advanced using either endoscopic or radiological imaging guidance to an area where surgery is to be performed. Under endoscopic or diagnostic imaging guidance the apparatus is positioned so tissue (208, 210) to be resected is manipulated into an inner cavity of the apparatus. The apparatus then cuts the diseased tissue after stapling and retains the diseased tissue within the apparatus. The rent resulting in a border of healthy tissue is anastomosed with surgical staples.

La présente invention concerne un procédé et un appareil chirurgical (12) permettant de réséquer des tissus (210) de préférence sur des tissus luminaux (208), la partie restante de l'organe étant anastomosée de préférence au moyen d'agrafes ou d'autres moyens de suture, par voie endoluminale. L'appareil peut s'introduire au travers d'un orifice physiologique naturel ou d'une incision chirurgicale, à la suite de quoi on fait progresser l'appareil en le guidant grâce à un moyen d'imagerie endoscopique ou radiologique jusqu'au site de l'intervention. Avec le guidage par imagerie endoscopique ou de diagnostic on amène l'appareil en position de façon que le tissu (208, 210) à réséquer est introduit par manipulation dans une cavité de l'appareil. L'appareil coupe ensuite le tissu malade après avoir posé les agrafes et retient le tissu malade à l'intérieur de l'appareil. La déchirure produisant une frange de tissu sain est anastomosée au moyen d'agrafes chirurgicales.
