摘要： An implantable lead may have a distal shocking coil that is configured to include a predetermined buckle region in order to limit potential cardiac damage that might otherwise occur if the implantable lead is too stiff. An implantable lead may have a proximal shocking coil that is configured to have a flexibility that more closely matches the flexibility of the lead body on either side of the proximal shocking coil.

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.

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： A system for therapeutically stimulating a His bundle includes an implantable pulse generator and a multi-polar medical electrical lead. The generator is configured for subcutaneous implantation and to generate a pacing stimulus. The lead includes a connector assembly, a flexible tubular body, a distal tip assembly and coil conductors. The body extends intravascularly from the generator to a location proximate the His bundle and includes a proximal end, a distal end, and a longitudinal lumen. The tip assembly includes an electrode, a fixation helix, and a shank portion. The helix extends to a location proximate the His bundle and is operable as an electrically isolated electrode. The shank portion extends within the lumen and includes a receptacle for receiving a stylet tip. The conductors extend longitudinally through the lumen and are coupled to the electrode and the helix. One or both of the conductors defines a stylet lumen.
