An elongated device and a system that at the same time allow acquisition of temperature-related data of high spatial and temporal resolution from hollow structures together with other relevant data of physical or chemical variables. In a preferred embodiment infrared or visible light sensors are used to obtain thermal or color images from the inner surface during imposed change of the temperature in the lumen of the hollow structure. The disclosure makes it possible to evaluate thermal variations when the inner surface returns to pre-change thermal conditions. High-resolution data can be obtained with the disclosure. The disclosure further includes a system with rotators, injection pumps, a control unit and display operably coupled to one or more of the data acquisition and processing system.

An anorectal expulsion device includes a balloon having a wall that extends between proximal and distal ends of the balloon and defines a balloon interior. The balloon interior contains a self-expanding, low compression-set material (e.g., open cell foam). The device also includes a catheter that extends through the proximal end of the balloon and at least a portion of the balloon interior. An interior of the catheter is in fluid communication with the balloon interior. The device also includes a termination component (e.g., a cap or a valve) coupled to the catheter at a position along the catheter that is outside of and proximal to the proximal end of the balloon (e.g., at the proximal end of the catheter). The physical configuration of the termination component is adjustable, and controls whether the balloon interior is in fluid communication with the external environment.

The present invention provides an improved breath analyzer and breath test method to determine the presence of disease in humans, including but not limited to, the bacterium H. pylori in a subjects digestive tract. In certain embodiments, the present invention provides a universal breath testing platform and methods of testing for diseases of the gastrointestinal tract, the liver, the kidneys, and the lungs, along with testing for cancer, infections, and metabolic diseases.

An ingestible device is disclosed which can produce spectral data of one or more analytes, as well as associated methods for characterizing the gastrointestinal tract of a subject which contains such analytes. Related kits and systems are also disclosed.

The present invention relates to a capsule-type endoscope assembly which can be assembled or disassembled in a digestive organ of an examinee, and a capsule-type endoscope system using same. A capsule-type endoscope of the present invention can be actively operated by application of an external magnetic field. In addition, according to the present invention, after an examinee has separately swallowed various diagnosis and treatment devices modularized according to a purpose of diagnosis and treatment, the diagnosis and treatment devices can be assembled in a digestive organ of the examinee. Therefore, a function of a capsule-type endoscope can be extended to various diagnosis and treatment areas conventionally covered by a conventional general endoscope.

Methods and apparatus are provided for high resolution intravital imaging and for chronic optical imaging of tissues such as lung.

An example of a system for monitoring and treating a medical condition of a patient may include signal inputs to receive patient condition signals indicative of a state of inflammatory bowel disease (IBD), a signal processing circuit configured to process the patient condition signals and generate patient condition parameters indicative of the state of IBD using the processed patient condition signals, and a medical condition analyzer configured to analyze the patient condition parameters and determine the medical condition including the state of IBD using an outcome of the analysis. The patient condition parameters may include one or more physiological marker parameters each representative of a physiological marker of IBD and one or more quality of life parameters each being measure of quality of life of the patient.
