A bougie having the dimensions of a standard bougie used widely by first responders is further configured to emit tight with an intensity that transilmminates a patient's neck; thus the position of the bougie is visible to the first responder when placed in the patient's airway. The bougie includes a light source, which may be a luminescent chemical combination contained in a chamber of the bougie. The luminescent chemical may have a high intensity and a short duration. The light source may be a light-emitting diode powered by an onboard battery and emitting light into a fiber-optic cable that emits light from the distal end and/or from interruptions in a reflecting coating that allows transverse exit of some of the light. The light source may be a chemilmninescent material or compound. All components of the bougie are sized to pass through an endotracheal tube without removing any of the components.

An apparatus for intraoral scanning includes an elongate handheld wand that has a probe. One or more light projectors and two or more cameras are disposed within the probe. The light projectors each has a pattern generating optical element, which may use diffraction or refraction to form a light pattern. Each camera may be configured to focus between 1 mm and 30 mm from a lens that is farthest from the camera sensor. Other applications are also described.

A handheld wand comprises a probe at a distal end of the elongate handheld wand. The probe includes a light projector and a light field camera. The light projector includes a light source and a pattern generator configured to generate a light pattern. The light field camera includes a light field camera sensor, the light field camera sensor comprising an image sensor comprising an array of sensor pixels, and an array of micro-lenses disposed in front of the image sensor such that each micro-lens is disposed over a sub-array of the array of sensor pixels.

A medical device system may include a control unit comprising one or more processors that implement an algorithm to enhance images obtained by a medical device. The one or more processing boards perform the steps of: receiving a first image from the first viewing element; determining a current illumination value of the first image; determining a first difference between the current illumination value and a target high illumination value if the current illumination value is greater than the target high illumination value; determining a second difference between the current illumination value and a target low illumination value if the current illumination value is less than the target low illumination value; generating a new illumination value, using at least one of the first difference and the second difference; and converting the new illumination value to a first voltage value for application to one or more illuminators of the medical device.

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.

An endoscope (100) includes an insertion tube device (2) and a control device (8). The insertion tube device (2) includes an elastic support unit (3), a lens unit (4), and a tubular sleeve unit (7). The elastic support unit (3) includes a distal disk (31), a proximal disk (33), an intermediate disk (32), first and second springs (34, 35) respectively connected between the disks (31, 32, 33). The lens unit (4) includes a lens seat (41) and a lens module (42). The tubular sleeve unit (7) is sleeved on the lens seat (41) and the elastic support unit (3). The control device (8) includes a grip (81), and an angulation control module (85) connected to the insertion tube device (2). The angulation control module (85) is operable to move the distal disk (31) and to deflect the first spring (34), thereby controlling angle of the distal disk (31).

An endoscope device includes a head tube having a front opening and a lateral opening, a front image capturing lens disposed in the head tube and facing the front opening, an optical fiber disposed in the head tube and located at one side of the front image capturing lens, a lateral image capturing lens disposed in the head tube and facing the lateral opening, and a lateral light source disposed in the head tube and arranged adjacent to the lateral image capturing lens. As such, the endoscope device of present invention uses the optical fiber to transmit lights to the front image capturing lens and uses the lateral light source to provide lights to the lateral image capturing lens, such that the overall volume can be effectively reduced and a high intensity lighting effect can be achieved, thereby improving image capture resolution and image recognition accuracy.

Several configurations of optical systems are disclosed herein. In some embodiments, the optical system includes a substrate having a first surface and a second surface, and a first reflector disposed on the substrate and configured to receive light. The light includes at least one of a first wavelength of light and a second wavelength of light. The first reflector is configured to reflect the first wavelength of light along a first light path toward a first diffractive lens and to transmit the second wavelength of light toward a second reflector. The second reflector is configured to reflect the second wavelength of light along a second light path toward a second diffractive lens.

The disclosure relates to an endoscopic system that includes an image sensor, an emitter and an electromagnetic radiation driver. The image sensor includes a pixel array and is configured to generate and read out pixel data for an image based on electromagnetic radiation received by the pixel array. The pixel array includes a plurality of lines for reading out pixel data.
