1. A tissue anchor delivery device comprising:
a handle;
an elongate shaft extending from the handle;
a pusher tube disposed at least partially within a lumen of the elongate shaft;
a pusher hub coupled to the pusher tube;
a needle disposed at least partially within a lumen of the pusher tube;
a needle hub coupled to the needle; and
an actuator configured to be fixed to the pusher hub and the needle hub, the actuator further being configured to:
advance the needle hub and the pusher hub a first distance, thereby causing a tip of the needle to protrude from a distal end of the elongate shaft;
disengage from the needle hub;
advance the pusher hub a second distance relative to the needle hub, thereby causing a distal end of the pusher tube to advance over the needle and push a coiled sutureform off of the needle; and
travel a third distance to cause the coiled sutureform to convert to a knot form.
