    Abstract: Intrabody MRI-compatible medical devices with a rigid stylet body with opposing distal and proximal ends with a wall enclosing at least one cavity extending therebetween. The stylet body has first and second laterally spaced apart and opposing external longitudinally extending recessed surfaces and at least one pair of transversely spaced apart apertures extending through the wall and at least one conductor having a length that extends through the cavity then exits the cavity to define at least one external loop extending between the distal end of the stylet body and the pair of transversely spaced apart apertures. First and second legs of each loop snugly abut a respective first and second recessed surface of the stylet body to thereby cooperate with the stylet body to define a substantially cylindrical shape. The at least one conductor with the at least one loop is configured to act as an MRI antenna.

    Abstract: 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.

    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.
