1. A device for fastening a first segment of lower esophageal sphincter tissue to a second segment of fundus tissue, the device comprising:
- a tissue fastener having a coil-shaped portion;
an elongate body configured for insertion into the esophagus, the elongate body having a proximal end and a distal end portion, and a passageway extending from the proximal end to the distal end portion to allow the passage of the fastener through the elongate body;
an element connected to and pivoting from the distal end portion of the elongate body, the element having an extended position at an angle to an axis of the elongate body and a retracted position substantially parallel to the axis of the elongate body to hold the first and second tissue segments between the element and the distal end portion of the elongate body; and
a tissue fastener advancer located in the passageway for advancing the tissue fastener in the passageway to the distal end portion of the elongate body and into the first and second tissue segments.
