Uterine Artery Ligation Devices

摘要

A device useful for ligating an anatomical structure, e.g., a uterine artery, includes a crochet hook-like shaft, and tubular filament holder, and a housing that includes a thumb-slide attached to the shaft. After inserting the filament holder into tissue adjacent to the artery, the shaft is inserted to a point next to the holder, and a hook on the end of the shaft is used to snare the filament and pull it around the artery. The filament can then be tied down, ligating the artery.

1. A device useful for ligating an anatomical structure, the device comprising:
an elongate shaft having a proximal end and a distal end, the shaft distal end comprising a distal-facing hook; an elongate tube comprising a proximal end, a distal end, and side port adjacent to said distal end, and a lumen extending proximally from said side port; a housing; wherein the tube is fixed in said housing and extends distally from the housing; wherein the shaft is partially positioned in said housing, and is longitudinally movable relative to the housing between a proximal position, in which said hook is adjacent to said housing, and a distal position, in which said hook is adjacent to said tube side port; and a thumb-slide attached to the shaft and longitudinally movably mounted to the housing.
