摘要： This disclosure describes an implantable medical lead, and method of making such a lead or components of the lead, that reduces the undesirable effects the fields generated by an MRI device may have on the implantable medical lead and the implantable medical device. The implantable medical lead includes an RF filter placed in series with an electrical path to an electrode of the lead. In one example, the RF filter may comprise a conductor wound in such a manner that it provides an inductance and capacitance that provides the RF filter with a resonant frequency, and in some instances, multiple resonant frequencies. At frequencies around the resonant frequency of the RF filter, the RF filter presents a high impedance, thereby blocking the signal from or at least attenuating the signal propagating to the electrode. At frequencies far from the resonant frequency, the RF filter presents a low impedance.

摘要： A conductor assembly for a medical electrical lead includes a web and plurality of conductors. The web includes a plurality of longitudinally extending elements, or sidewalls, each of which define a longitudinally extending lumen, and a plurality of longitudinally extending connectors, each of which join a pair of adjacent sidewalls. Each of the plurality of conductors extends within a corresponding lumen, and each may include an insulative jacket. If each conductor includes an insulative jacket, the jacket is preferably formed from one or more of the following materials: PEEK, PVDF and polysulfone. One or more of the connectors of the web may be flexible to allow for a connected separation, or a gap between adjacent sidewalls; and one or more of these connectors may further include a discrete wall section adapted to facilitate widening of the corresponding gap. Preferably the conductor assembly is coiled for incorporation into the lead.

摘要： A medical device lead is presented that includes an electrode assembly having a first electrode located near a distal end of the electrode assembly and a second electrode located near a proximal end of the electrode assembly. The electrode assembly also includes a conductive elongated coupler that is electrically coupled to the first electrode and capacitively coupled to the second electrode. At low frequencies and DC (e.g., during delivery of stimulation therapy), the capacitive coupling between the conductive elongated coupler and the second electrode presents a high impedance allowing little current to be redirected from the first electrode to the second electrode. However, at high frequencies (e.g., during an MRI scan) the capacitive coupling between the conductive elongated coupler and the second electrode presents a low impedance, resulting in a significant amount of induced current being redirected to the second electrode and dissipated into bodily fluid surrounding the second electrode.
