Therapy delivery system including a navigation element

A navigation element for a modular therapy delivery system, the element comprising:

• an elongate outer tube including a lumen extending longitudinally therethrough;
• an elongate inner tube extending within the outer tube lumen along at least a portion of a length of the outer tube, the inner tube including a lumen extending longitudinally therethrough;
• and
• at least one electromagnetic receiver assembly mounted in between the inner tube and the outer tube;
• the receiver assembly including a receiver coil and a conductor;
• the receiver coil including a first end, a second end and a coiled wire;
• and
• the conductor including a first insulated wire extending alongside a second insulated wire, the conductor coupled to the coiled wire at and extending in between the receiver coil and the inner tube, wherein the coiled wire of the receiver assembly receiver coil includes a first end and a second end, the first and second ends of the coiled wire disposed in proximity to the receiver coil first end;
• the first and second wires of the receiver assembly conductor each include an end, the conductor ends extending away from one another in proximity to the receiver coil first end;
• and
• the coiled wire first end is wrapped about the end of the first conductor wire and the coiled wire second end is wrapped about the end of the second conductor wire.
