Patent ID: 8715294

Claim:
A transgatric instrument providing a sterile and repeatable pathway to and through a gastric wall for the purpose of facilitating endoscopic transgastric procedures, comprising: a tubular main body including a plurality of lumens each defining a guide tube, each of the guide tubes having a proximal end and a distal end, the distal end being shaped and dimensioned for positioning adjacent a desired location along the gastric wall; a first fixation mechanism is provided at the distal end of at least one of the guide tubes for selectively securing the distal end of the guide tube at a desired location along the gastric wall and a second fixation mechanism is provided at the distal end of at least one of the guide tubes for selectively securing the distal end of the guide tube at a desired location along the gastric wall; an otomy creation device, circumferentially smaller than the respective guide tubes, extends through the respective guide tubes, the otomy creation device includes a distal end shaped and dimensioned for cutting and dilating the gastric wall; the first fixation mechanism is composed of a plurality of shape memory rods embedded in pathways formed in a wall of the guide tube; and wherein the second fixation mechanism includes a pivotally and longitudinally moveable distal fixation arm having an outwardly oriented protrusion selectively moved from an aligned orientation to and out of alignment orientation and a pivotally moveable proximal fixation arm having an outwardly oriented protrusion selectively moved from an aligned orientation to and out of alignment orientation.
