Apparatus and method for securing the stomach to the diaphragm for use, for example, in treating hiatal hernias and gastroesophageal reflux disease

A method for repairing a hiatal, comprising:

• inserting transorally an elongated member into an esophagus of a patient;
• pulling a vacuum through a plurality of orifices on the elongated member to grip an inner wall of the esophagus;
• after gripping the esophagus, moving the elongated member aborally toward a stomach to position the stomach and a gastroesophageal junction aboral of a diaphragm;
• advancing a fastener deployer and the elongated member down a throat and the esophagus into the stomach and using the fastener deployer to fasten a lesser curve of the stomach to a right crus of the diaphragm;
• pivotally attaching a support arm to a distal end of the elongated member and for supporting the fastener deployer in close proximity to a fundus of the stomach;
• utilizing a visualization device to visualize the lesser curve of the stomach being fastened to the right crus of the diaphragm;
• mounting a fastener from the fastener deployer onto a tissue piercing deployment wire, the fastener comprising a first member, a second member, the first and second members each having first and second ends;
• connecting the first member and the second member of the fastener with a connecting member fixed to each of the first and second members intermediate the first and second ends and extending between the first and second members, the connecting member having sufficient length to pass through both the right crus of the diaphragm and the lesser curve of the stomach;
• the first member has a through channel along a longitudinal axis arranged to be slidingly received on the tissue piercing deployment wire;
• and
• wherein the first member has a longitudinal slit that can be made larger through separation to allow the tissue piercing deployment wire to snap into and out of the through channel.
