1. A transport device for increasing biological activity, comprising:
a base configured to be carried externally to skin of a subject;
two or more base anchors configured to be coupled to the base and configured to statically couple the base to cortex of a bone of a subject;
a translatable interface configured to engage an internal portion of the subject;
a leadscrew dynamically coupling the base to the translatable interface, wherein the leadscrew is configured to rotate about a leadscrew axis while substantially maintaining its longitudinal position along the leadscrew axis in relation to the base, such that the translatable interface is capable of independent movement in relation to the base along the leadscrew axis;
a screw drive rotatably coupled to the leadscrew and configured to couple to a rotatable mating tool that is configured to rotate the leadscrew via the screw drive, wherein the leadscrew is coupled to the base independently from the coupling of the two or more base anchors, and wherein the leadscrew comprises a head having an outer perimeter, the outer perimeter comprising a structural feature; and
an engagement feature carried by the base, wherein physical reaction between the structural feature and the engagement feature when the leadscrew is moved between an engaged position and a disengaged position produces a physical disturbance configured to be sensed by a user via an audible and/or tactile vibration, to provide information to the user related to an extent of relative displacement between the translatable interface and the base.
