Abstract
A continuous congruent length of stranded flexible Drilling Energy Transfer Member (DETM) constructed to transfer and balance action/reaction forces between an energy source and a working tip such that torque, tensile, compression and self supporting forces are constrained while the DETM operates in multiple positions of tight curvature and straight run and while translating into and out of such extremes, the balance being maintained between the extensor/torque outer configuration and an inner tensile/compressor configuration.
