  • Patent number: 11022433
    Abstract: A method for reconstructing a surface of a three-dimensional object involves a projection of a laser spot pattern onto the surface of the three-dimensional object by a laser, and a generation of a series of endoscopic images as an endoscope is translated and/or rotated relative to the three-dimensional object. Each endoscopic image illustrates a different view of a laser spot array within the laser spot pattern as projected onto the surface of the three-dimensional object by the laser. The laser spot array may be identical to or a subset of the laser spot pattern. The method further involves a reconstruction of the surface of the three-dimensional object from a correspondence of the different views of the laser spot array as illustrated in the endoscopic images.

  • Patent number: 10806396
    Abstract: Systems and methods for delivering a drug with a tracer or contrast agent are disclosed herein, as are systems and methods that generally involve CED devices with various features for reducing or preventing backflow. In some embodiments, CED devices include a tissue-receiving space disposed proximal to a distal fluid outlet. Tissue can be compressed into or pinched/pinned by the tissue-receiving space as the device is inserted into a target region of a patient, thereby forming a seal that reduces or prevents proximal backflow of fluid ejected from the outlet beyond the tissue-receiving space. In some embodiments, CED devices include a bullet-shaped nose proximal to a distal fluid outlet. The bullet-shaped nose forms a good seal with surrounding tissue and helps reduce or prevent backflow of infused fluid.
