    Abstract: An MRI-compatible base is configured to support an MRI-compatible head support frame. The base is configured to be secured to a gantry associated with an MRI scanner, and to extend across a width of the gantry. The base allows the head support frame to be moved to any of a plurality of locations across the width of the gantry, and allows the head support frame to rotate about two orthogonal axes so as to be positioned at any of a plurality of angles relative to the gantry.

    Abstract: A passive MRI-compatible guidewire includes an elongate, flexible tubular shaft, an elongate core wire of non-ferromagnetic material, and an elongate spring coil of non-ferromagnetic material axially surrounding the elongate core wire to form a distal end portion. The core wire includes opposite first and second end portions separated by an intermediate portion. The intermediate portion has a round cross-section, and the first and second end portions each have a non-round cross-section. The first end portion of the core wire resides within an inner lumen of the tubular shaft and is secured therewithin. The spring coil includes opposite first and second ends, and the spring coil second end is secured to the core wire second end portion via polymeric material that forms a rounded distal tip of the guidewire. The guidewire includes a plurality of spaced-apart, passive MRI-visible markers.

    Abstract: A trajectory frame for use with an MRI-guided interventional system includes a base having a patient access aperture formed therein. The base is configured to be secured to the body of a patient. 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 distal end portion is positioned proximate the patient access aperture. The guide is configured to removably receive various devices therein for quick release therefrom, including a targeting cannula, drill guide and drill bit, skull fixation device and driver, and catheter guide.

    Abstract: Surgical devices such as a device guide for a trajectory frame for image-guided procedures, is configured with first and second elongate and cooperating semi-circular members that together define a longitudinally extending open channel and that can separate along longitudinally extending split lines into discrete first and second elongate semicircular members. The surgical devices with the first and second semi-circular members can include a device guide and dock and lock inserts that are detachably held by dock and lock members to a guide support column that also concurrently holds the device guide during at least part of an image guided procedure.

    Abstract: An MRI-guided interventional system for use with a patient and an interventional device includes a base, a trajectory guide frame, and a mounting device. The base is configured to be secured to a body of the patient. The trajectory guide frame includes a targeting cannula. The targeting cannula has an elongate guide bore extending axially therethrough, defining a trajectory axis, and being configured to guide placement of the interventional device. The trajectory guide frame is operable to move the targeting cannula relative to the base to position the trajectory axis to a desired intrabody trajectory to guide placement of the interventional device in vivo. A plurality of patient engagement structures are provided on the base and are configured to penetrate tissue of the body and to space the base apart from the tissue. The system further includes a plurality of fasteners configured to secure the base to the body.
