Improved localization of the capsule in acoustic capsule endoscopy is provided by using analysis of the frames of the acoustic images to deduce the relative motion of the capsule from frame to frame. This idea can be supplemented with any combination of: further localization methods; propulsion of the capsule via acoustic radiation reaction; bidirectional communication and system level feedback control; energy harvesting; photoacoustic (or x-ray acoustic) imaging; and adding therapy and/or sensor capabilities to the capsule.

A processor first executes activation through a first program stored in a main memory when there is an activation instruction, a switching unit switches a program from the first program to a second program in sub memory when activation through the first program is impossible within a first period of time, and the processor halts power supply from the battery when activation through the second program is impossible within a second period of time.

A capsule endoscopic system is disclosed for receiving data from a capsule device and providing inductive power to the capsule device wirelessly, where the capsule endoscopic system incorporates a feature to automatically protect the capsule device and the docking device from damage if the capsule device is docked in a backward orientation. In one embodiment, the docking device comprises a current sense circuit to detect the current flowing through the primary coil or primary drive circuit. The occurrence of wrong orientation can be detected from the current. A detection/control circuit can be used to provide the needed control in order to prevent damage to the system. In another embodiment, a resonant circuit comprising a capacitor and the primary coil is used to provide the needed protection when the capsule device is docked with a wrong orientation.

An endoscope includes an insertion portion. First and second electronic instruments are located in the insertion portion and are supplied with drive power from different systems. A plurality of power limiting portions limit the drive power supplied to the first and second electronic instruments, respectively, via mutually different systems. First and second wirings, at least a portion of which are located inside the insertion portion, connect respective power limiting portions with the respective ones of the first and second electronic instruments. A ground conductor extends from one end of the insertion portion to the other end of the insertion portion and is connected between a first connection connecting the first electronic instrument and the first wiring and a second connection connecting the second electronic instrument and the second wiring.

A camera attachment device includes a mounting ring for attachment over a camera lens of a mobile phone. A periscope module includes a first periscope end for attachment to the mobile phone at the mounting ring. A second periscope end is for capturing images. A periscope tube is connected between the first periscope end and the second periscope end. A light collector is attached to the mounting ring. The light collector is shaped to extend over a light source from the mobile phone. The light collector is configured to receive light from the light source and direct the light through the mounting ring and into the first periscope end. The light exits the second periscope end so as to provide illumination for capturing the images.

A modular endoscope system comprises a first modular section comprising imaging and illumination units, and a patient-insertable second modular section that can be detached to the first modular section via an attachment mechanism, wherein the first modular section is positionable at a distal end section of the second modular section and is configured to illuminate and image a portion of a patient anatomy. A method of using a modular endoscopy system comprises attaching a first modular section of the modular endoscopy system to a second modular section of the modular endoscopy system, positioning at least a portion of the modular endoscopy system within a patient, illuminating and imaging a portion of a patient anatomy via the first modular section, removing the modular endoscopy system from the patient, and detaching the second modular section from the first modular section after removal of the modular endoscopy system from the patient.

A portable imaging system includes a case having a first portion coupled to a second portion. The second portion includes an interior storage portion, a wireless imaging system that has a housing, a camera sensor disposed within the housing, and a light source. The portable imaging system further includes an imaging scope removably coupled to the wireless imaging system, a controller that is communicatively coupled to the wireless imaging system, and a display screen that is disposed on an interior surface of the first portion of the case. The display screen is communicatively coupled to the controller and the interior storage portion is configured to receive and store the wireless imaging system and the imaging scope.

A handheld surgical endoscope has a disposable, single-use portion that includes a fluid hub and cannula, and a re-usable portion that includes a handle and display module. The distal tip includes LED illumination and an imaging module that feeds live video to the display module. The single-use and re-usable portions mate and un-mate with each other via physically separated mechanical and electrical connectors. The surgical endoscope is configured for operation by a single clinician in many procedures.

An endoscopic system may include a catheter or tubing and at least one optical sensor disposed along the catheter or tubing and configured to capture image information from a body lumen when disposed within the body lumen and activated. The system may further include an untethered module operatively arranged with the at least one optical sensor and configured to store or transmit image information captured by the at least one optical sensor. The catheter or tubing, at least one optical sensor and module may be portable during use.
