20120289825 | FLUOROSCOPY-BASED SURGICAL DEVICE TRACKING METHOD AND SYSTEM - A method and system for assisting a physician track a surgical device in a body organ of a subject during a procedure includes fluoroscopic based registration, tracking, and optimizing a fluoroscopy position. An initial registration step includes receiving a 3D image data of a subject in a first body position, receiving a real time fluoroscopy image data, and estimating a deformation model or field to match points in the real time fluoro image with a corresponding point in the 3D model. A tracking step includes computing the 3D location of the surgical device and displaying the surgical device and the 3D model of the body organ in a fused arrangement. Optimizing the fluoroscope camera pose includes computing a candidate camera pose to assist the surgeon to track a surgical device based on features of the surgical device, position of the patient, and mechanical properties or constraints of the fluoroscope. | 11-15-2012 |

20120288173 | SURGICAL ASSISTANCE PLANNING METHOD USING LUNG MOTION ANALYSIS - A medical analysis method for estimating a motion vector field of the magnitude and direction of local motion of lung tissue of a subject is described. In one embodiment a first 3D image data set of the lung and a second 3D image data set is obtained. The first and second 3D image data sets correspond to images obtained during inspiration and expiration respectively. A rigid registration is performed to align the 3D image data sets with one another. A deformable registration is performed to match the 3D image data sets with one another. A motion vector field of the magnitude and direction of local motion of lung tissue is estimated based on the deforming step. The motion vector field may be computed prior to treatment to assist with planning a treatment as well as subsequent to a treatment to gauge efficacy of a treatment. Results may be displayed to highlight. | 11-15-2012 |

A control segment may be associated with the conduit to limit the degree of radial expansion. The conduit further includes a plurality of deflectable members extending from the ends of the center section. A tissue barrier may coaxially surround the conduit such that tissue ingrowth is prevented. The conduits may also include hold-down members and bioactive coatings that serve to prevent ejection of the conduit as well as prevent narrowing of the passageway due to tissue ingrowth. | 10-13-2011 |

It generally includes fluidly connecting the lung to an extrapleural airway such as the trachea. In one variation, a conduit is deployed to place the lung and the trachea in fluid communication which allows trapped oxygen-reduced air to pass directly out of the lung and into the trachea. Removing nonfunctional air from the lung tends to improve the gaseous exchange of oxygen into the blood and decompress hyper-inflated lungs. Sealant and biocompatible adhesives may be provided on the exterior of the conduit to prevent side flow, leaks and to otherwise prevent air from entering spaces not intended to receive air such as the pleura space. | 12-11-2008 |
