    摘要： A substance delivery device includes an elongated tubular body having opposing proximal and distal ends, and a diaphragm that is in slideable sealing engagement with an inside wall of the tubular body. The diaphragm is movable in opposite first and second directions within the tubular body. A substance is contained within the tubular body between the diaphragm and the tubular body distal end, and a slave fluid is contained within the tubular body between the diaphragm and the tubular body proximal end. When pressure is exerted on the slave fluid, the slave fluid causes the diaphragm to move and eject the substance through the tubular body distal end.

    摘要： 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.

    摘要： 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.

    摘要： Fiber optic systems with an MR compatible mouse in an MR scanner room that connects to a fiber optic computer mouse interface that is attached to a fiber optic cable that connects to a USB port of a computer in the MR control room to allow the mouse in the MR scanner room to move a cursor on a monitor in communication with the computer in the control room of an MRI suite during an MRI guided surgical procedure. The fiber optic cable(s) can be routed though a conventional RF wall waveguide and avoids the need for additional holes in the penetration panel for connectors. The fiber optic systems can also include up converters and down converters for providing fiber optic video signals from cameras in the MR scanner room to display video signal on the monitor.
