Fiber optic sensor guided navigation for vascular visualization and monitoring

A method for visualizing branches of a lumen includes inserting (402) a fiber optic shape sensing device into a lumen and determining (404) changes in the lumen based upon strain induced in the fiber optic shape sensing device by flow in the lumen. Locations of branches are indicated (410) on a rendering of the lumen. An instrument is guided (414) to the locations of branches indicated on the rendering.

SOFT ROBOTS, SOFT ACTUATORS, AND METHODS FOR MAKING THE SAME

A material-mapped actuator useful as, or as part of, a soft robot along with automated methods of design and manufacture. The actuator exhibits mechanical properties that spatially vary along a coordinate system of the actuator. The actuator body has an initial shape with a corresponding initial map of mechanical attributes consisting of locally-varying stiffness at each point in a volume of the actuator body. The actuator is configured to change to a different shape or distribution of mechanical properties upon being activated by an actuation medium. The map of mechanical attributes influences and determines the new shape or distribution. The material-mapped actuator can incorporate a spatially-varying distribution of mechanical properties that dictates multiple desired shapes as the actuation medium is applied, including an actuation sequence in which the actuator transitions from a first shape to a desired intermediate shape(s), and from the intermediate shape to a desired final shape.
