Beschreibung
Zusammenfassung:	A shielded component or network for an active medical device (AMD) implantable lead includes an implantable lead having a length extending from a proximal end to a distal end, all external of an AMD housing, and a passive component or network disposed somewhere along the length of the implantable lead. The passive component or network including at least one inductive component having a primary magnetic field line axis. A conductive shield or housing having a primary longitudinal axis substantially surrounds the inductive component or the passive network. The inductive component's magnetic field line axis is oriented substantially orthogonally to the primary longitudinal axis of the conductive shield or housing.
