Abstract
An endoscopic ligating apparatus is provided that can be used to dispense multiple ligating bands or rings about several lesions. In one embodiment, a barrel supporting a plurality of bands stretched around its circumference is removably engaged to the insertion end of an endoscope. A trip wire extends through a working channel of the endoscope and includes at least one piece of flexible material extending from the distal end of the barrel and wrapped around the end of the barrel. The ligating bands are situated over the flexible material. As tension is applied to the trip wire by way of an activating mechanism, the flexible material retracts within the barrel so as to draw the ligating bands successively to the end of the barrel.
