    Abstract: MRI compatible localization and/or guidance systems for facilitating placement of an interventional therapy and/or device in vivo include: (a) a mount adapted for fixation to a patient; (b) a targeting cannula with a lumen configured to attach to the mount so as to be able to controllably translate in at least three dimensions; and (c) an elongate probe configured to snugly slidably advance and retract in the targeting cannula lumen, the elongate probe comprising at least one of a stimulation or recording electrode. In operation, the targeting cannula can be aligned with a first trajectory and positionally adjusted to provide a desired internal access path to a target location with a corresponding trajectory for the elongate probe. Automated systems for determining an MR scan plane associated with a trajectory and for determining mount adjustments are also described.

    Abstract: An elongate electrical lead assembly that reduces localized heating due to MR scanner-induced currents includes a first elongate electrical lead having a series of alternating single layer coil sections and multi-layer coil sections, a second elongate electrical lead having a series of alternating single layer coil sections and multi-layer coil sections, and a third elongate electrical lead having a coiled section that coaxially surrounds the first and second electrical leads. Each multi-layer coil section of the second electrical lead is coiled around a respective single layer coil section of the first electrical lead, and each single layer coil section of the second electrical lead is coiled around a respective multi-layer coil section of the first electrical lead.

    Abstract: An MRI-compatible intrabody device includes an elongated flexible shaft having a distal end portion, an opposite proximal end portion, an electrical connector interface configured to be in electrical communication with an MRI scanner, and a tracking coil assembly adjacent the shaft distal end portion. The tracking coil assembly includes a first spool having opposing first and second end walls and a second spool having opposing third and fourth end walls. The second spool is in end-to-end relationship with the first spool such that the second and third end walls are in adjacent, spaced-apart relationship. A tracking coil is wound around the first spool, and a coaxial cable is wound around the second spool. An outer conductor of the coaxial cable is connected to one end of the tracking coil and the inner conductor of the coaxial cable is connected to an opposite end of the tracking coil.
