Insertion instrument for anchor assembly

An insertion instrument assembly configured to eject a first anchor and a second anchor at respective target locations, the first and second anchors including respective first and second anchor bodies that extend substantially along a respective direction of elongation, each of the first and second anchors further including a respective actuation member, the insertion instrument assembly comprising:

• a casing;
• a cannula fixed with respect to the casing, the cannula extending out relative to the casing in a distal direction along a cannula axis to a distal end of the cannula, the cannula defining an elongate opening that extends along the cannula axis;
• a first pusher member aligned with the elongate opening of the cannula;
• a second pusher member aligned with the elongate opening of the cannula so as to be movable within the cannula along the cannula axis, wherein 1) the second pusher member contains the first anchor body, 2) the elongate opening of the cannula contains the second anchor body and 3) the first pusher member is configured to be depressed in the elongate opening so as to eject the first and second anchor bodies from the cannula and into the respective target locations;
• a coupling assembly that releasably translatably couples the first pusher member to the second pusher member, such that, in a first mode of operation the first and second pusher members are coupled together and translate together to eject the second anchor body from the cannula, and in a second mode of operation, the first and second pusher members are decoupled from each other so that the first pusher member is translatable with respect to the second pusher member to eject the first anchor body from the second pusher member and out the cannula;
• and
• a plunger attached to the first pusher member, the plunger configured for rotational movement with respect to the casing so as to transition the coupling assembly from the first mode of operation to the second mode of operation so as to eject the first and second anchors from the cannula,
• wherein, when a tensile force is applied to the respective actuation member substantially along the direction of elongation, the respective first and second anchor bodies expand along a respective second direction perpendicular with respect to the respective direction of elongation.
