摘要： An inflatable in-vivo capsule endoscope and method of operation is provided. The inflatable in-vivo capsule endoscope may include a sensing device for capturing in-vivo images and one or more permanent magnets for magnetically guiding the endoscope, housed interior to a capsule-shaped body. The inflatable in-vivo capsule endoscope may include an inflatable buoy attached externally to the capsule-shaped body. An inflation device may inflate the in-vivo capsule endoscope to reduce its specific gravity by injecting gas into the inflatable buoy, such that when the inflatable buoy is injected with an above threshold volume of gas, the inflatable in-vivo capsule endoscope floats in liquid. The inflatable in-vivo capsule endoscope may be magnetically guided via its permanent magnets when exposed to an externally generated magnetic field. A reduced magnetic field strength and external magnet size may be used to magnetically navigate an inflated capsule floating in liquid than a conventional uninflated capsule.

摘要： A capsule endoscope device, system and method for dynamically adjusting a color illumination spectrum. A plurality of different color groups of LEDs may emit light, recorded by an image sensor, corresponding to a plurality of different respective wavelength subranges. A driving circuit may send a driving current to independently activate each different color group of LEDs during entirely or partially non-overlapping time pulses. A single color group of LEDs is independently activated at any one time, and the plurality of different color groups of LEDs are sequentially activated in successive time pulses to simulate a white light or multi-color illumination spectrum over a plurality of the time pulses. The activation pattern of the color groups of LEDs may be dynamically adjusted, in real-time, to achieve a flexible and customizable illumination spectrum ideal for imaging a variety of different environments e.g., in the GI tract.

摘要： Systems for liquid biopsy and/or drug delivery may include a capsule endoscope and a tether coupled to the capsule endoscope. The tether may include a flexible member with a lumen in fluidic communication with a port configured to permit passage of fluid, and the port may be, for example, on the capsule endoscope or the tether. In methods for liquid biopsy and/or drug delivery, the capsule endoscope may be advanced into a gastrointestinal tract of a patient, and navigated to a region of interest, where a patient sample may be withdrawn and/or a therapeutic substance may be administered through the lumen (e.g., through the port).
