  • Patent number: 9548215
    Abstract: An endoprosthesis, a method for imaging an endoprosthesis, a method of making an endoprosthesis involve a polymeric substrate that has been modified to have voids embedded within the substrate. The voids are sized to scatter optical radiation from within the substrate so that an optical coherence tomography (OCT) image can be obtained in which an interior region of the substrate can be easily differentiated from empty space and other structures that surround the endoprosthesis. The voids allow for OCT visualization of the polymeric substrate which may be difficult to visualize by other methods such as fluoroscopy.

  • Patent number: 9526408
    Abstract: A light source device of an electronic endoscope system has first and second semiconductor lasers. In a vascular observation mode, one of the semiconductor lasers is used in a full light state (100% rated output) while the other is used in a reduced light state (for example, 10% rated output). First and second images of an internal body portion are captured with a color imaging device under illumination of two patterns, respectively. Correlation operation of pixel values of three colors is performed between the two images. Noise components, caused by the first or second semiconductor lasers in the light reduced state, are removed from the first and second images. An oxygen saturation level of blood in a blood vessel is calculated using the first and second images with the noise components removed.

  • Patent number: 9451885
    Abstract: Systems and methods that facilitate analysis of superficial tissue based at least in part on a depth-selective fiber optic probe are discussed herein. The depth-selective fiber optic probe can include an illumination fiber for providing light to the superficial tissue, a collection fiber for collected reflected light, a ball lens that couples the fibers, and a protective overtube that houses the ball lens and fibers. The distances between the ball lens and fibers and between the fibers can be optimized based on several factors, such as by minimizing the illumination spot size, maximizing the overlap between the illumination and collection spots, and based on the angle between the illumination and collection beams.
