20090112084 | MRI-GUIDED MEDICAL INTERVENTIONAL SYSTEMS AND METHODS - An MRI-guided interventional system for use with a body of patient and an interventional device includes a base and a targeting cannula. The base is configured to be secured to the body of the patient. The targeting cannula has an elongate guide bore extending axially therethrough and an inlet and an outlet at opposed ends of the guide bore. The guide bore defines a trajectory axis extending through the inlet and the outlet and being configured to guide placement of the interventional device. The 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. The inlet tapers from an outer diameter distal from the guide bore to an inner diameter proximate the guide bore to guide and facilitate insertion of the interventional device into the guide bore. | 04-30-2009 |
20090118610 | MRI-GUIDED LOCALIZATION AND/OR LEAD PLACEMENT SYSTEMS, RELATED METHODS, DEVICES AND COMPUTER PROGRAM PRODUCTS - MRI compatible localization and/or guidance systems for facilitating placement of an interventional therapy and/or device in vivo include: (a) a mount adapted for fixation to a patient; (b) a targeting cannula with a lumen configured to attach to the mount so as to be able to controllably translate in at least three dimensions; and (c) an elongate probe configured to snugly slidably advance and retract in the targeting cannula lumen, the elongate probe comprising at least one of a stimulation or recording electrode. In operation, the targeting cannula can be aligned with a first trajectory and positionally adjusted to provide a desired internal access path to a target location with a corresponding trajectory for the elongate probe. Automated systems for determining an MR scan plane associated with a trajectory and for determining mount adjustments are also described. | 05-07-2009 |
20090131783 | METHODS, SYSTEMS AND COMPUTER PROGRAM PRODUCTS FOR POSITIONING A GUIDANCE APPARATUS RELATIVE TO A PATIENT - A method for positioning a guide device for placement of an interventional object in a body, the guide device having a guide axis, includes: determining a target point in the body and a reference point, wherein the target point and the reference point define a planned trajectory line (PTL) extending through each; determining a visualization plane, wherein the PTL intersects the visualization plane at a sighting point; mounting the guide device relative to the body to move with respect to the PTL, wherein the guide device does not intersect the visualization plane; determining a point of intersection (GPP) between the guide axis and the visualization plane; and aligning the GPP with the sighting point in the visualization plane. | 05-21-2009 |
20090171184 | MRI SURGICAL SYSTEMS FOR REAL-TIME VISUALIZATIONS USING MRI IMAGE DATA AND PREDEFINED DATA OF SURGICAL TOOLS - MRI-Surgical systems include: (a) at least one MRI-compatible surgical tool; (b) a circuit adapted to communicate with an MRI scanner; and (c) at least one display in communication with the circuit. The circuit electronically recognizes predefined physical characteristics of the at least one tool to automatically segment MR image data provided by the MRI scanner whereby the at least one tool constitutes a point of interface with the system. The circuit is configured to provide a User Interface that defines workflow progression for an MRI-guided surgical procedure and allows a user to select steps in the workflow, and wherein the circuit is configured to generate multi-dimensional visualizations using the predefined data of the at least one tool and data from MRI images of the patient in substantially real time during the surgical procedure. | 07-02-2009 |
20100137704 | MEDICAL MATS WITH ELECTRICAL PATHS AND METHODS FOR USING THE SAME - The disclosure describes medical mats that provide electrical paths with connectors that connect to various electronic medical or surgical tools. The medical mats can reduce the lengths of cables and define routes that preventing cross-over, looping and/or bunching of loose lengths of long cables. | 06-03-2010 |
20100198052 | MRI-COMPATIBLE ARTICULATING ARMS AND RELATED SYSTEMS AND METHODS - The disclosure describes articulating arms that are supported directly or indirectly by MRI scanner beds for use during MRI-guided procedures. | 08-05-2010 |
20100217113 | CABLE MANAGEMENT SYSTEMS FOR MRI SYSTEMS AND RELATED METHODS - The disclosure describes cable management systems that provide adjustable lengths of cables that connect to various electronic medical or surgical tools. The systems can reduce the lengths of loose or hanging cables and define routes that preventing cross-over, looping and/or bunching of loose lengths of long cables. | 08-26-2010 |
20130006095 | METHODS ASSOCIATED WITH MRI SURGICAL SYSTEMS FOR REAL-TIME VISUALIZATIONS USING MRI IMAGE DATA AND PREDEFINED DATA OF SURGICAL TOOLS - MRI-Surgical systems include: (a) at least one MRI-compatible surgical tool; (b) a circuit adapted to communicate with an MRI scanner; and (c) at least one display in communication with the circuit.
