Apparatus and method for forming folds in visceral organ

An instrument (10) for forming a fold (64) in an internal tissue wall of a patient. The instrument (10) comprises an elongate implement (11) for insertion into a patient proximate a tissue wall, optionally through a natural body opening. The instrument (10) includes one or more of the following: (a) a traction device (20) configured to engage wall tissue and pull the wall tissue to form a protrusion of the wall tissue; (b) a ligation device (30) configured to at least partially surround a protrusion in the wall tissue to form a fold (64) in the tissue wall; (c) securing means (40) for securing the fold (64) in the tissue wall. 一种用于在病患的内部组织壁中形成折叠(64)的器械(10)。该器械(10)包括细长器具(11)，其用于插入靠近组织壁的病患体内、可选地穿过自然身体开口。该器械(10)包括以下一个或多个：(a)牵拉装置(20)，其构造成接合壁组织并拉动壁组织以形成壁组织的突起；(b)结扎装置(30)，其构造成至少部分地环绕壁组织中的突起以在组织壁中形成折叠(64)；(c)固定装置(40)，其用于在组织壁中固定折叠(64)。
