    Abstract: Trajectory frame assemblies for image guided surgical systems have a trajectory frame with a support column that can removably secure different components such as a tracking probe and an MER driver adapter to define and/or follow a desired intrabody trajectory. The trajectory frame assemblies include fins attached to the column support and a platform optionally with an X-Y table and/or arcuate reference brackets that are attached to the trajectory frame assemblies and can hold a reference frame with fiducials.

    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.

    Abstract: An elongate electrical lead assembly that reduces localized heating due to MR scanner-induced currents includes a first elongate electrical lead having a series of alternating single layer coil sections and multi-layer coil sections, a second elongate electrical lead having a series of alternating single layer coil sections and multi-layer coil sections, and a third elongate electrical lead having a coiled section that coaxially surrounds the first and second electrical leads. Each multi-layer coil section of the second electrical lead is coiled around a respective single layer coil section of the first electrical lead, and each single layer coil section of the second electrical lead is coiled around a respective multi-layer coil section of the first electrical lead.
