Abstract: A novel endoscope, which can be a spectrally encoded endoscope (SEE) probe having forward-view, side-view, or a combination of forward and side views is provided herein. The SEE probe includes a light guiding component, a light focusing component, and a grating component. The probe is configured to forward a light such as a spectrally dispersed light from the grating component to a sample with no intermediate reflections between light guiding component and the grating component. A triangular grating, such as a staircase grating or an overhang grating may be used as the grating component.

Abstract: A system and method for displaying an endoscope image in a preferred orientation. An endoscope scans a sample with spectrally encoded light by rotating imaging optics inside an endoscope guide. A processor generates an image based on light returned from the sample, and rotates the image by a first angle offset value and a second angle offset value to display the rotated image in the preferred orientation. The first offset value is an angle difference between a specific direction in which the image is to be displayed on a display and a direction in which the tip of the endoscope is oriented with respect to the imaging plane. The second offset value is an angle difference between a direction of the line of scanning light projected onto a plane perpendicular to the tip and the specific direction in which the image is to be displayed.

Abstract: A Spectrally Encoded Forward View or Multi-View Endoscope, Probe, and Imaging Apparatus and system, and methods and storage mediums for use therewith, are provided herein. At least one apparatus or system may comprise a first waveguide; an optical system; and a diffraction grating. The first waveguide may be for guiding light from a light source to an output port of the first waveguide. The optical system may comprise at least a first reflecting surface and a second reflecting surface. The first reflecting surface may be arranged to reflect light from the output port of the first waveguide to the second reflecting surface. The second reflecting surface may be arranged to reflect light from the first reflecting surface back through the first reflecting surface to the diffraction grating. The diffraction grating may diffract light from the second reflecting surface in several lights/colors of non-zero diffraction orders in a first direction.

Abstract: One or more devices, systems, methods and storage mediums for characterizing, examining and/or diagnosing, and/or measuring viscosity of, a sample or object are provided herein. Such information may be obtained in application(s) using a system that includes a rotary junction, an elongated extender or at least one repeater attached to the rotary junction and a rotatable probe attached to the elongated extender and/or the at least one repeater. Examples of such applications include imaging, evaluating and diagnosing biological objects, such as, but not limited to, for Gastro-intestinal, cardio and/or ophthalmic applications, and being obtained via one or more optical instruments. The extenders and/or repeaters may be used with one or more forms of imaging, such as, but not limited to, Spectrally Encoded Endoscopy (“SEE”) and Optical Coherence Tomography (“OCT”).

Abstract: There is provided medical devices and methods of use. The medical device comprising: an elongated tube; a balloon disposed over the elongate tube having at least one drug and at least one fluorescent agent on an outer surface of the balloon; an optical probe at the distal end of the elongate tube comprising an optical fiber configured to guide illumination light coming from a light source and an optical member configured for fluorescence imaging; and one or more detectors configured for fluorescence detection. The probe may comprise an optical probe for fluorescence imaging, and optionally an additional probe component for structural imaging or physiological sensing. The method can be particularly useful for determining whether sufficient dose of a drug has been transferred from a balloon to the lumen.

Abstract: An endoscopic probe extending from a proximal end to a distal end thereof, and configured to be inserted in a tubular lumen to observe a sample is disclosed. The probe includes a first waveguide enclosed within an inner sheath and extending from the proximal end to the distal end along an axis of the inner sheath; and a plurality of second waveguides having at least the distal ends thereof arranged in one or more rings around the inner sheath to surround the distal end of the first waveguide. At the distal end, the axis of each of the second waveguides is tilted with respect to the axis of the first waveguide by a tilt angle which can be adjustable. This novel endoscopic probe has a resultant numerical aperture larger than the numerical aperture of each of the second waveguides, and it may be applicable to forward-viewing spectrally encoded endoscopes (SEE).
