摘要： An implantable medical device lead includes an inner conductor coil comprising one or more generally cylindrically wound filars. The inner conductor coil is configured to have a first inductance value greater than or equal to 0.2 μH/inch when the inner conductor coil is subjected to a range of radio frequencies. The implantable medical device lead also includes a multi-filar outer coil comprising two or more generally cylindrically wound filars. The multi-filar outer coil is configured to have a second inductance value greater than or equal to 0.1 μH/inch when the multi-filar outer coil is subjected to the range of radio frequencies.

摘要： Systems and methods for improving response of implantable leads to magnetic fields during medical procedures such as magnetic resonance imaging (MRI) are described. In various embodiments, the lead includes an inner conductor that is helically shaped and radially surrounded, at least in part, by one or more high-voltage conductors. The high-voltage conductor can be mechanically and/or electrically coupled, via a coupler, to the shocking coil. The pitch of the inner and/or outer conductor can be varied (e.g., continuously or at certain points) along the length of the lead. In some embodiments, the filar thickness, the pitch, and the mean coil diameter of the inner coil, the high voltage conductor coil, and the shock coil can be configured such that these coils have a desired inductance value when subjected to externally applied electromagnetic energy at radio frequencies commonly generated by MRI scanners (e.g., 40 MHz to 300 MHz).

摘要： An implantable medical system includes a medical lead including an insulating sheath and a conductor and an anchoring device. The anchoring device defines an inner lumen adapted to coaxially receive the medical lead, where the inner lumen has an effective diameter. The anchoring device includes a sleeve including a substantially elongate body defining an outer surface and an inner bore. The anchoring device also has a compression member including a first end, a second end, and an intermediate portion between the first and second ends. The compression member is at least partially embedded in the sleeve such that compression of the first and second ends of the compression member toward one another causes the effective diameter of at least a portion of the inner lumen of the anchoring device to reversibly increase.
