An apparatus includes a shaft, an imaging head, and a processor. The shaft includes a distal end sized to fit through a human nostril into a human nasal cavity. The imaging head includes an image sensor assembly, a plurality of light sources, and a plurality of collimators. At least some of the light sources are positioned adjacent to the image sensor assembly. Each collimator is positioned over a corresponding light source of the plurality of light sources. The processor is configured to activate the light sources in a predetermined sequence. The image sensor assembly is configured to capture images of a surface illuminated by the light sources as the light sources are activated in the predetermined sequence.

Single viewpoint panoramic imaging attachments for a colonoscope are disclosed that are compact in size and provide 360-degree side and rear-views in a single image. One panoramic attachment assembly includes a plurality of micro-imaging subsystems that are positioned around a central opening. Each micro-imaging subsystem includes a reflector to receive light that is reflected from a surrounding tissue, an imaging lens, and a detector to generate signals corresponding to one section of a panoramic image of the surrounding tissue. The micro-imaging subsystems are arranged to all have a common view point, and are configured to collectively form a full 360-degree image of the surrounding tissue.

An endoscopic probe comprises a flexible light guide extending from a proximal end of the endoscopic probe to a distal end portion of the endoscopic probe. A motor is disposed in the distal end portion of the endoscopic probe. The motor comprises a rotor coupled to drive rotation of a light deflector. The light deflector is located between the rotor and a distal end of the endoscopic probe. The rotor is configured to provide a light path extending axially through the rotor. The light path arranged to carry light between the light deflector and the light guide. The endoscopic probe may be applied for helical scanning walls of small passages in any of a wide range of modalities such as OCT, fluorescence imaging, Raman spectroscopy, reflectance imaging.

A direct vision cryosurgical and methods of use are described herein where the device may generally comprise an elongated rigid structure with a distal end, a proximal end, and a central lumen. The distal end may comprise a non-coring optically transparent needle tip with at least one lateral fenestration in communication with the central lumen. The distal end may also house at least one imaging device configured for distal imaging. A proximal end of the device may comprise a handle with a means for connecting the imaging device(s) to an imaging display(s), and a means for accessing bodily tissue in the vicinity of the distal end with a cryo-ablation probe through the central lumen and the lateral fenestration(s) for diagnostic or therapeutic purposes.

An endoscope pipe with a central, elongated observation window on the distal end, whereby several light outlet openings for fiberoptic end surfaces are positioned close to the observation window for illuminating the angle area observed through the observation window and the light outlet openings are positioned asymmetrically in relation to the longitudinal extension of the observation window and/or the fiberoptic end surfaces are held in the light outlet openings in such a way that light is beamed from the fiberoptic end surfaces into the angle area in various directions.

The disclosure relates to an endoscopic system. The system may include a single optical fiber. The system may further include a light source which transmits light into the single optical fiber. An image sensor may be provided within the endoscopic system and disposed at a distal end of the single optical fiber. The endoscopic system may be additionally fitted with a diffuser on the distal end of the single optical fiber which outputs a light cone that is broader than an output of the single optical fiber without the diffuser.

A surgical access assembly and method of use is disclosed. The surgical access assembly comprises an outer sheath and an obturator. The outer sheath and obturator are configured to be delivered to an area of interest within the brain. Either the outer sheath or the obturator may be configured to operate with a navigational system to track the location of either within the brain. Once positioned at a desired location, the obturator is removed, leaving a distal end of the outer sheath adjacent an area of interest, and creating a working corridor. Interrogation of the area of interest may be performed to evaluate a disorder and/or abnormality, as well as evaluate treatment regimes. Interventional devices may also be introduced to the area of interest, as well as a variety of treatments.

Provided herein is a tip component of a multi camera endoscope, the tip component accommodates a plurality of cameras configured to jointly provide a field-of-view (FOV) of at least about 270 degrees and a plurality of front illumination modules; wherein the tip component includes a plurality of window elements of sapphire glass soldered using a noble-metal, within respective openings on the housing thereof, wherein each of the cameras and illumination modules is positioned behind a respective window element. Further provided are methods of manufacturing the tip component and methods of using the same.

The present specification is directed towards endoscopes, such as colonoscopes, that provide a broader field of view and allow extended access of surgical tools and also enable efficient packing of all necessary elements in the tip section, while maintaining their functionality. Also described are methods and systems for capturing and displaying still and video images using an endoscope corresponding to a left-side looking, a front-looking and a right-side looking viewing element of an endoscopic tip generated in a native aspect ratio.

The disclosure relates to an endoscopic light source that includes a first emitter. The first emitter may emit light of a first wavelength at a dichroic mirror which reflects the light of the first wavelength to a plurality of optical fibers. The endoscopic light source further comprises a second emitter. The second emitter may emit light of a second wavelength at a second dichroic mirror which reflects the light of the second wavelength to the plurality of optical fibers. In one embodiment, the first dichroic mirror may be transparent to the light of the second wavelength, allowing the light of the second wavelength to pass through the first dichroic mirror.
