1. An anchor device for securing a position of a medical instrument, the anchor device comprising:
a retainer body comprising a proximal end, a distal end, and an anchor that extends distally from the distal end;
a tether member attached to the proximal end of the retainer body that extends proximally from the retainer body, and
a second body member that is attachable to the tether member at a position proximally spaced away from the proximal end of the retainer body such that the tether member is positioned between a distal end of the second body member and the proximal end of the retainer body;
wherein the retainer body releasably couples to a medical instrument while the second body member is releasably coupled to the medical instrument, wherein the tether member includes a plurality of mating locations spaced apart at different longitudinal positions relative to the proximal end of the retainer body, and wherein the second body is releasably and directly matable to the tether member at any of the plurality of mating locations.
