Abstract: Devices for transferring fluid to or from a subject include an elongate tubular cannula having opposing proximal and distal ends with an axially extending lumen. The devices also include an elongate needle having opposing proximal and distal ends. The elongate needle is configured so that the distal end of the needle extends out of the distal end of the cannula a suitable adjustable distance. The devices also include a housing with a length adjustment mechanism that adjusts a length between the tip of the needle and the distal end of the tubular cannula.

Abstract: Circuits and computer program products onboard and/or adapted to communicate with an scanner that electronically recognize predefined physical characteristics of the at least one tool to automatically segment image data provided by the scanner whereby the at least one tool constitutes a point of interface with the system. The circuits and computer program products are configured to provide a User Interface that defines workflow progression for an image guided surgical procedure and allows a user to select steps in the workflow, and generate multi-dimensional visualizations using the predefined data of the at least one tool and data from images of the patient in substantially real time during the surgical procedure.

Abstract: RF/MRI compatible leads include at least one conductor that turns back on itself at least twice in a lengthwise direction, and can turn back on itself at least twice at multiple locations along its length. The at least one electrical lead can be configured so that the lead heats local tissue less than about 10 degrees Celsius (typically about 5 degrees Celsius or less) or does not heat local tissue when a patient is exposed to target RF frequencies at a peak input SAR of at least about 4 W/kg and/or a whole body average SAR of at least about 2 W/kg. Related devices and methods of fabricating leads are also described.

Abstract: A trajectory frame for use with surgical navigation systems includes a base having a patient access aperture formed therein. A yoke is mounted to the base and is rotatable about a roll axis. A platform is mounted to the yoke and is rotatable about a pitch axis. An elongated guide is secured to the platform and includes opposite proximal and distal end portions and a bore that extends from the proximal end portion to the distal end portion. The guide is configured to removably receive various devices therein for quick release therefrom, including an optical tracking probe (which may be a universal tracker) detectable by a camera-based tracking system or an EM probe detectable by an EM navigation system, a microelectrode probe driver adapter, a drill guide and drill bit, skull fixation device and driver, and a catheter guide.

Abstract: An MRI-compatible tip assembly for an MRI-compatible medical device includes a first tubular member, a second tubular member, a ring electrode, and a tip electrode. The tip electrode proximal end is secured to the first tubular member distal end. The second tubular member distal end is inserted through the ring electrode and is secured to the first tubular member proximal end. When assembled, the tip assembly is a substantially rigid structure. Each tubular member has a recessed portion for a tracking coil.

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.
