Abstract: Some embodiments are directed to MRI/RF compatible medical interventional devices. A plurality of spaced apart high impedance circuit segments are configured to have a high impedance at a high range of radiofrequencies and a low impedance at a low range of frequencies. The high impedance circuit segments may comprise co-wound coiled inductors and can reduce, block or inhibit RJ-transmission along the lead system (20) during exposure to RF associated with a high-Held magnet MRI systems, while permuting passage of low frequency physiologic signals, treatments and/or stimuli. The devices can include at least one electrode.

Abstract: A head support assembly includes a base configured to be removably secured to an MRI scanner gantry, a head support frame attached to the base, and a longitudinally extending head coil apparatus adjustably secured to the head support frame. The head support frame includes a pair of elongated arms that extend outwardly in adjacent, spaced-apart, substantially co-planar relationship to form an area for receiving the head of a patient. Each arm includes a respective free end, and a head engagement rod is adjustably associated with each respective arm free end. The head engagement rods are configured to engage a patients head within the head support frame. One or more additional head engagement rods may extend outwardly from the head support frame between the pair of arms.

Abstract: A magnetic resonance probe may include a plurality of center conductors, at least some center conductors including a conductive core and an insulator disposed at least partially about the core along at least a portion of the core, a first dielectric layer disposed at least partially about the plurality of center conductors in a proximal portion of the probe, an outer conductive layer at least partially disposed about the first dielectric layer, and a plurality of electrodes, at least one electrode being coupled to one of the center conductors and disposed at least partly on a probe surface.
