Abstract:
1. A method of plicating a tissue with a tissue plication device comprising a helical fastener having a distal portion with a first pitch, a proximal portion with a second pitch that is smaller than the first pitch, and a distal tip, the method comprising: providing a coil deployment device having a hub formed at a distal end, the hub having a hollow interior space defined by a peripheral wall that includes threading formed on an inner surface of the peripheral wall and a stop in the form of a floor that extends between the peripheral wall proximal to but separate from the threading and prevents the helical fastener from further movement in a proximal direction, the stop having a through opening formed therein for allowing passage of a guide wire, wherein the floor comprises a wall that extends radially inward relative to the threading to form a surface against which the helical fastener seats; engaging a proximal end of the proximal portion of the helical fastener with the threading so as to cause the proximal portion to seat against the stop; introducing the distal tip into the tissue; advancing the distal portion of the helical fastener into the tissue by rotating the distal end of the coil deployment device; continuing the advancing until the proximal portion of the helical fastener occupies a space previously occupied by the distal portion, thereby plicating the tissue; disengaging the proximal end of the proximal portion of the helical fastener with the threading.
