MRI-conditionally safe medical device lead

A medical device comprising:

• a pulse generator;
• and
• a lead including a lead body, a proximal connector, an outer conductive coil extending through the lead body, and an inner conductor assembly extending coaxially within the outer conductive coil,
• the inner conductor assembly coupled to a first electrode at a distal end of the inner conductor assembly, the inner conductor assembly comprising one or more filars arranged in a plurality of serially connected current suppression modules, each current suppression module having a multi-layer configuration comprising a first inner coil of the one or more filars wound in a first winding direction, a second intermediate coil of the one or more filars coaxial with the first winding and wound in a second winding direction opposite the first winding direction, and a third outer coil of the one or more filars coaxial with the first and second windings and wound in the first winding direction,
• the outer conductive coil having a proximal end coupled to the proximal connector and a distal end coupled to a second electrode and including one or more filars wound in the first winding direction from the proximal end to the distal end.
