    摘要： A conductor assembly for a medical device lead includes a helically coiled conductor including a plurality of turns having a coil pitch and an outer diameter and consisting of one filar having a filar diameter. The coil pitch and outer diameter are selected based on the filar diameter to minimize heating of the helically coiled conductor in the presence of an MRI field. A polymer sheath is formed about the helically coiled conductor such that the coil pitch of the unifilar helically coiled conductor is maintained. The polymer sheath is configured to increase a torque transmitting capacity of the helically coiled conductor.

    摘要： A medical device lead includes a lead body having a proximal end and a distal end. The proximal end is configured for connection to a pulse generator. One or more electrodes are at a distal end of the lead body, and a lead conductor extends through the lead body and is electrically coupled to at least one of the one or more electrodes. The conductor is configured to deliver electrical signals between the proximal end and the at least one of the one or more electrodes. A sacrificial conductor extends through the lead body adjacent to lead conductor and is configured to fail at a lower stress than the lead conductor.

    摘要： An implantable medical lead exhibits reduced heating under MRI conditions. The lead includes a multi-layer coil conductor including an inner coil layer, a middle coil layer disposed around the inner coil layer, and an outer coil layer disposed around the middle coil layer. Each of the coil layers is characterized by one or more of a filar thickness, a coil pitch, or a coil diameter configured such that the coil conductor exhibits a high inductance when exposed to MRI radiation. Each of the coil layers is electrically connected to the other coil layers to provide parallel conductive paths resulting in a coil conductor resistance suitable for defibrillation lead applications.
