| 20110270040 | PLANNING FOR CURVATURE INTERACTIONS, MULTIPLE RADII OF CURVATURE AND ADAPTIVE NEIGHBORHOODS - Planning deployment of a medical robot based on concentric cannulas takes into account multiple radii of curvature. The radii of curvature are dependent on tube diameter. Tubes of smaller diameter can have tighter radii of curvature. Planning also takes into account moment of inertia and elasticity of tubes. For the purposes of planning, an A* algorithm is used for cost wave propagation together with a configuration space, a cost metric, and a neighborhood. The neighborhood is adaptive. The adaptive neighborhood can be different for each node in the configuration space data structure and depends on curvature affecting properties of individual tubes used to achieve a path from a most distal point to a most proximal point within a body to be examined. | 11-03-2011 |

| 20110295199 | PLANNING AND ASSEMBLY OF COMPENSATING CONCENTRIC CANNULAS - A specification for a device including a set of concentric cannulas may be discovered to have an actual path different from a desired path, due to interactions between cannulas that effect net curvature of the device. The choice of particular cannulas may be corrected by performing a calculation taking into account curvature affecting properties of the individual cannulas including radius of curvature, elasticity, and moment of inertia. This calculation is preferably performed iteratively starting with a most distal cannula and iterating through the cannulas to the proximal end, accumulating net effect of curvature affecting properties. | 12-01-2011 |
