Abstract:
1. A medical electrical lead, comprising: an elongate body including a proximal end portion, a middle portion and a distal end portion; and a first coil wound about at least one of said proximal end portion, said middle portion, and said distal end portion, and a second coil wound about at least one of said proximal end portion, said middle portion, and said distal end portion, said first coil being wound more loosely than said second coil such that said second coil provides at least one of a different inductance compared to an inductance provided by said first coil, and a different parallel parasitic capacitance compared to a parasitic capacitance provided by said first coil; wherein the coils provide filtering of radio frequency (RF) signal-coupled electrical energy at at least one of said proximal end portion and said distal end portion.
