Abstract

The present invention generally provides treatment devices for ligating and resecting biological tissue, in particular, ligating and resecting internal biological tissue while being used in conjunction with a flexible endoscope, and methods for use thereof. The aim being to maintain haemostasis and subsequently allow for the delivery of electrical current to said biological tissue. The treatment devices are in particular for the ligation and removal of large pedunculated colonic polyp and comprise a snare member (5) and a ligating member (4).
