Circuit for a lead of an implantable medical device

A method of manufacturing an implantable electric circuit for medical stimulation, the method comprising:

• connecting a plurality of capacitors to a network of resistors, wherein
• each of the plurality of capacitors is configured to couple radio frequency energy from one of a plurality of electrically conductive filaments of a lead to the network of resistors, and
• the network of resistors is configured to connect the plurality of capacitors together to dissipate the radio frequency energy between the plurality of electrically conductive filaments, wherein the filaments of the lead are arranged annularly within a multi lumen conductor and the network of resistors comprises one resistor between adjacent filaments to thereby form a ring of resistors capacitively coupled to the electrically conductive filaments and
• wherein the circuit is integrated within the lead.
