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 300MHz).

摘要： Medical device leads with magnetic shielding and methods of shielding medical device leads from magnetic fields during medical procedures such as magnetic resonance imaging (MRI) are described. An illustrative implantable medical device includes a lead including a lead conductor having a length and a helically coiled ribbon shield radially surrounding the lead conductor along at least a portion of the length of the lead. The ribbon shield can include one or more inner ribbon conductors and/or one or more outer ribbon conductors. The outer ribbon conductor can have a variable width (e.g., a necked-down configuration, an arrowhead configuration, or an undulating configuration) along the length of the lead. In some cases, the helically coiled ribbon has a variable pitch along the length of the lead that may be the same as or different from that of the lead conductor pitch.

摘要： A medical device lead includes a conductor and one or more band stop filters. The conductor extends through a lead body and includes a proximal end and a distal end. The one or more band stop filters each have a first end and a second end and include a conductive coil. At least one of the first end and second end of each band stop filter is coupled to the conductor. A length of each band stop filter is such that, at magnetic resonance imaging (MRI) frequencies, the band stop filter phase shifts an MRI-induced signal on the conductor by 180 to attenuate the MRI-induced signal on the conductor.

摘要： Systems and methods for shielding implantable leads from 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 outer shielding conductors. The pitch of the inner conductor, and in some cases also the outer conductor, can be varied (e.g., continuously or at certain points) along the length of the lead, forming a plurality of high impedance points along the length of the lead which result in the dissipation of electromagnetic energy at an interrogation frequency of a magnetic resonance imaging device (e.g., 64 MHz, 128 MHz, or the like). In some embodiments, the variance in the pitch of the inner conductor follows a sinusoidal function, a modified square-wave function, or some other repeating pattern.

摘要： A medical device lead includes a tubular conductive element disposed over a lead body. The tubular conductive element includes at least one segment having one or more kerfs formed radially therethrough in a predetermined configuration so as to affect at least one electrical property, e.g., electrical impedance, of the segment. The segment may form a shocking conductor of the medical device lead. The tubular conductive element may alternatively include proximal, intermediate and distal segments each having one or more kerfs formed radially therethrough, where the one or more kerfs in each of the proximal and intermediate segments are configured so that these segments each have a higher electrical impedance than the distal segment. A layer of insulative material is disposed over the proximal and intermediate segments, so that the proximal and intermediate segments of the tubular conductive element are operable to filter electromagnetic energy from an external source.
