Abstract:
1. An implantable lead, comprising: a) an implantable lead body having a length extending from a proximal end to a distal end; b) a conductor disposed within the implantable lead body from the proximal end and terminating at the distal end comprising an electrode or sensor contactable with biological cells; c) a passive electrical filter circuit comprising an inductor, a low pass filter or a bandstop filter having an equivalent electrical circuit schematic wherein an inductance is in parallel with a capacitance and having an overall circuit Q wherein the resultant 3 dB bandwidth is at least 10 kHz such that the bandstop filter attenuates RF current flow over a range of frequencies; and d) an electromagnetic shield at least partially surrounding the inductor, the low pass filter or the bandstop filter.
