  • Publication number: 20190046271
    Abstract: A method includes, receiving a first sequence of first positions of a medical device that moves in a body of a patient. The first positions of the medical device are visualized to a user, by automatically moving a dummy device, external to the body, in a second sequence of second positions that mimics the first sequence.

  • Publication number: 20180368917
    Abstract: A method and system for automatic landmark registration and registration using trajectory information and shape sensing during an endoscopic procedure, such as bronchoscopy, are described herein. A segmentation centerline of airways of a lung may be generated based on a pre-operative computed tomography (CT) image of the lung. Landmarks may be automatically detected on the segmentation centerline corresponding to bifurcations in the airways of the lung. A location data point cloud of locations of a catheter through the airways of the lung during navigation may be generated. A bounding volume of the airways of the lung may be generated and a bounding volume centerline may be detected. Landmarks may be detected on the bounding volume centerline for the same bifurcations. Then, the two sets of landmarks may be mapped as part of registration. The trajectory information with shape sensing may be used to provide non-rigid or fine registration.

  • Publication number: 20180342144
    Abstract: A conduit puncture alert method and apparatus are provided for a medical instrument having a flexible conduit through which a medical procedure is performed. In one embodiment, the flexible conduit is inserted into a subject. A highest degree of curvature of the conduit within the subject is sensed. A warning signal is then provided upon a condition that a curvature is sensed that exceeds a predetermined limit reflective of a maximum curvature permissible for a selected tool to be inserted through the conduit while avoiding puncturing of the conduit by the selected tool. For example, the method can be conducted with respect to a bronchoscope during a bronchoscopic procedure where a needle tool is to be used and the warning is given with respect to that tool when a conduit curvature is sensed that exceeds a predetermined limit determined with respect to the needle tool.

  • Publication number: 20180303506
    Abstract: Apparatus, including a probe having a distal end insertable into a nasal sinus of a human patient, and a location sensor positioned within the distal end. A sinuplasty balloon is positioned on the distal end at a selected opening of the nasal sinus. A processor receives first signals from the location sensor while the distal end is inserted into the nasal sinus and prior to positioning of the balloon at the selected opening, and generates a first map of the sinus. The processor inflates the balloon when it is at the selected opening, so as to enlarge the selected opening, and subsequently deflates the balloon. The processor then receives second signals from the location sensor and generates therefrom a second map of the sinus. The processor registers the first map with the second map and generates from the registered maps a numerical increase in size of the selected opening.
