Patent ID: 8055351

Claim:
An MRI/RF compatible medical device, comprising: an implantable elongate lead having at least a first electrode, a second electrode, a first axially extending conductor, and a second axially extending conductor, the first electrode electrically coupled to the first axially extending conductor and the second electrode electrically coupled to the second axially extending conductor, wherein, at each of a plurality of intermediate locations along a length of the elongate lead, at least one of a plurality of spaced apart capacitors is disposed between the first and second axially extending conductors to define a plurality of high impedance circuit segments, each high impedance circuit segment comprising at least a portion of the first axially extending conductor, at least a portion of the second axially extending conductor, and at least one of the plurality of spaced apart capacitors disposed between the portion of the first axially extending conductor and the portion of the second axially extending conductor, whereby the lead system has a high impedance at a target range of high radiofrequencies and a low impedance at low frequencies.
