1. A bidirectional biomechanical finger assembly for a user's residual finger, comprising:
an articulation assembly including a multiple-finger ring configured to receive and retain the residual finger and at least one adjacent finger, the multiple-finger ring selectively disposed upon the articulation assembly;
a distal coupler rotatively coupled with the articulation assembly;
wherein the articulation assembly is configured to utilize vertical movements of at least one of the residual finger and the at least one adjacent finger within the multiple-finger ring to articulate the distal coupler within a plane parallel to an x-z plane;
wherein the articulation assembly further comprises an adjustable ring tendon having a distal end, a proximal end, and a longitudinal adjustment mechanism disposed therebetween, the multiple-finger ring selectively disposed upon the adjustable ring tendon at a target location along the longitudinal adjustment mechanism.
