The embodiments of the present invention are directed to a novel wireless powered method, apparatus and tracking system without a wired interface to a moving catheter. The implant in the patient's body on the moving catheter is energized by an external ultrasound transmitter using acoustic pressure waves. As a general mode of operation, ultrasonic waves from outside of a patient's body are received by an array of transducer elements configured about the catheter disposed in a patient's body, wherein the array of transducer elements transforms a frequency into a resultant stored energy. The resultant stored energy powers one or more transceivers via a power management arrangement and enables RF frequencies in a desired band to be output and received by external sensors. Coupled with ultrasound backscattering capabilities, the catheter provides a dual mode for accurate triangulated locations of the distal end of a moving catheter.
