Abstract
An endoscopic overtube with articulating fingers extending from the distal end. The articulating fingers form an opening that may be expanded by a balloon. When positioned in a puncture site in a tissue wall, the articulating fingers dilate and enlarge the puncture site to allow for the body of the overtube to pass through the puncture site. In various embodiments, the fingers may further comprise cutting elements to assist in the dilation of the puncture site.
