1. An endoscopic deployment system for placing a suture anchor at a site within a mammal comprising:
an elongated flexible delivery member having proximal, intermediate, and distal regions, proximal and distal ends, an elongate shaft member having proximal and distal ends, a handle coupled to said proximal end of the shaft member, said handle including,
i) a stationary member defining a longitudinal slot;
ii) a movable member longitudinally displaceable over said stationary member, the movable member having a drive portion that rides in the slot; and
iii) a worm gear rotatably mounted in the slot, said worm gear having proximal and distal ends, said drive portion of said movable member having a bore with an opening that closely accommodates said worm gear such that when said movable member is displaced over said stationary member, said worm gear is rotated and results in rotation of the proximal end of said shaft member, and rotation of said proximal end of said shaft member causes the distal end of said shaft member to rotate;
a coupling assembly fixedly coupled to the distal region of said delivery member including an engagement post; and
a suture anchor having proximal and distal ends, a tubular receiver having a central longitudinal axis, a coil member positioned at said distal end of said suture anchor, and a suture eyelet rotatable relative to said receiver;
wherein:
said delivery member is operable between a first operable configuration and a second operable configurations;
when said delivery member is in said first operable configuration, said suture anchor is releasably coupled to said coupling assembly whereby said engagement post couples with said receiver and rotation of the distal end of the shaft member results in rotation of said suture anchor such that when said suture anchor is in contact with tissue, rotation of said distal end of said shaft member causes the coil member of said suture anchor to engage the tissue; and
when said delivery member is in said second operable configuration, said suture anchor is detached from said coupling assembly, said delivery member being operable between said first and second operable configurations.
