1. An anchor assembly configured to be implanted with respect to tissue, the anchor assembly comprising:
a helical anchor with a plurality of helical turns; and
an anchor housing;
wherein:
an anchor bore is defined in the anchor housing with internal threads through which the helical turns of the helical anchor extend;
the helical anchor has a proximal end and a distal end, the distal end extending away from the anchor housing as the helical anchor is advanced distally away from the anchor housing; and
the distalmost helical turn of the helical anchor, closest to the distal end of the helical anchor, has an outer diameter greater than a diameter of at least a distalmost internal thread of the anchor bore in which the distalmost helical turn of the helical anchor is positioned.
