Abstract: According to one aspect, a medical device system for visualizing internal patient anatomy may comprise: a shaft including a distal tip portion, the tip portion including an imaging device, and a signal modulator; and a control unit operatively coupled to the shaft and including a de-modulator. The imaging device may be configured to output a first signal to the signal modulator. The signal modulator may be configured to modulate the received first signal and output a modulated second signal to the control unit; and the de-modulator of the control unit may be configured to receive the modulated second signal, de-modulate the second signal, and output a de-modulated third signal. The control unit may be configured to output the de-modulated third signal to an electronic display.

Abstract: A method for performing a medical procedure may comprise advancing a first device through a first body lumen. A distal portion of the first device may include a magnet. The method may further comprise advancing a second device through a second body lumen. The second device may include a magnetic field sensor. The method may further comprise receiving a signal from the magnetic field sensor. The signal may be indicative of a magnetic field measured by the magnetic field sensor. The method may further comprise, if the received signal matches a magnetic field of the magnet, identifying a position of the magnet.

Abstract: A system for determining characteristics of tissue within a body of a patient may include a medical device. The medical device may include a distal end configured to be advanced within the body of the patient; at least one aperture at the distal end; a laser emitter operable to emit monochromatic light out from the distal end via the at least one aperture and onto target tissue; and at least one photodetector array. The at least one photodetector array may be configured to: receive light incident on the at least one aperture that is one or more of scattered by or reflected from the target tissue; and generate Raman spectroscopy image data based on monochromatic light incident on the at least one aperture, the Raman spectroscopy image data including an array of intensity values.

Abstract: A method is provided for enhancing video images in a medical device. The method includes receiving a first image frame and a second image frame from one or more image sensors. The first image sub-blocks are generated by dividing the first image frame. At least one curve to the first image sub-blocks are associated based on one or more look-up tables. A target in at least one of the first image sub-blocks is identified. Second image sub-blocks are generated by dividing the second image frame. At least one curve is associated to the second image sub-blocks based on the one or more look-up tables. The target is identified in at least one of the second image sub-blocks. Histogram enhanced images of the target in the first image sub-blocks and the second image sub-blocks are generated. A video image stream is generated based on the histogram enhanced images of the target.

Abstract: A method of generating a color image using a monochromatic image sensor. The method includes sequentially illuminating a surface in a plurality of colors, one color at a time. The monochromatic image sensor captures a plurality of image frames of the surface based on the plurality of colors. The plurality of image frames are identified, and at least one feature in the target of the plurality of image frames is highlighted. Color intensities of the plurality of image frames are normalized. A color intensity map of the target for each of the plurality of image frames is generated. A correlation score is determined by comparing each color intensity map of the plurality of image frames. The color image is generated based on the correlation score.
