<p>A ligating device includes an elongate tube (21) having an interior channel (23), and an axis extending between a proximal end and a distal end. A handle (32) is disposed at the proximal end of the tube. Distal portions of the tube define a recess (41) extending into the channel transversely of the axis. A suture (52) extending through the channel includes first portions disposed proximally of the recess and second portions disposed distally of the recess. An engagement apparatus (34) movable by operation of the handle engages the suture distally of the recess, and is operable to draw the suture (loop) into the tube. In this manner, the suture substantially encircles the conduit permitting ligation of the conduit. An associated method includes the steps of moving the engagement apparatus to engage the suture and withdraw the suture ends from the body after substantially encircling the body conduit.</p> |
