Abstract
A transgastric instrument provides a sterile and repeatable pathway to and through a gastric wall for the purpose of facilitating endoscopic transgastric procedures. The instrument includes at least one guide tube 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. The instrument also includes a fixation mechanism at the distal end of the guide tube 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 guide tube extends through the guide tube, the otomy creation device including a distal end shaped and dimensioned for cutting and dilating the gastric wall.
