Systems and methods for treating hypertension and other maladies are implemented using an implant device that is configured with one or more coils of ribbon which form ring-like structures when deployed in a patients vasculature and are interconnected via respective extension arms formed from at least one helical winding. In an illustrative example, the catheter is positioned in the patients aorta near the right angle junction with renal vasculature so that the axis of the catheter is substantially perpendicular to the axis of the vasculature. Through operation of an implant device delivery system having a pigtail distal end the ribbon emerges from the catheter tip and coils into the ring-like structures which deploy into the renal vasculature so that the longitudinal axes of the device and vasculature are substantially co-linear.
