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 conductor for connecting an electrode near a distal end of a medical electrical lead with an implantable medical device connected with a proximal end of the medical electrical lead includes a multi-filar coil wrapped around a central core. The multi-filar coil has an inductance of approximately 0.5 μH or greater, and the central core is non-conducting and provides reinforcement for the multi-filar coil.

摘要： The disclosure describes implantable medical systems that respond to occurrence of a lead-related condition by utilizing an elongated coil electrode in defining an alternative pacing therapy vector to maintain optimal drain of an IMD power supply. An exemplary system includes a medical electrical lead having an elongated electrode and an improved sensing and therapy delivery circuitry to provide the alternative pacing therapy vector responsive to the lead-related conditions. The system reconfigures the operation of the sensing and therapy delivery circuitry triggered by the switch to the alternative pacing therapy vector.

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： An implantable lead includes a defibrillation electrode and a sensor coupled thereto. The electrode and sensor are positioned along a body of the lead such that, when a fixation element couples the lead to an endocardial surface of a right ventricle, the sensor is located in a high flow region and a portion of the defibrillation electrode is located in proximity to a right ventricular apex.
