摘要：
A multilayer helical wave filter having a primary resonance at a selected RF diagnostic or therapeutic frequency or frequency range, includes an elongated conductor forming at least a portion of an implantable medical lead. The elongated conductor includes a first helically wound segment having at least one planar surface, a first end and a second end, which forms a first inductive component, and a second helically wound segment having at least one planar surface, a first end and a second end, which forms a second inductive element. The first and second helically wound segments are wound in the same longitudinal direction and share a common longitudinal axis. Planar surfaces of the helically wound segments face one another, and a dielectric material is disposed between the facing planar surfaces of the helically wound segments and between adjacent coils of the helically wound segments, thereby forming a capacitance.
