Computational techniques are applied to video images of polyps to extract features and patterns from different perspectives of a polyp. The extracted features and patterns are synthesized using registration techniques to remove artifacts and noise, thereby generating improved images for the polyp. The generated images of each polyp can be used for training and testing purposes, where a machine learning system separates two types of polyps.

According to one aspect, an implantable medical device may include an anchor assembly configured to anchor the medical device to a body lumen. The implantable medical device may also include a capsule. The capsule may include a pH sensor. The pH sensor may be configured to measure a pH of contents within the body lumen. The capsule may also include a power source, a controller, and an impedance sensor. The impedance sensor may be configured to measure an impedance within the body lumen.

A method and system for GI health condition monitoring and improvement, where the method includes steps for receiving signals associated with the GI condition, the signals encoding physiological data, behavioral data, environmental stress data, emotional data, and cognitive data of the user; determining a characterization of the GI condition upon processing the set of signals with a model; based upon the characterization, modulating content of a treatment comprising a set of components, the set of components comprising a subset of cognitive behavioral therapy (CBT) components for improving a state of the user; and administering the treatment to the user. The system and method can be provided as a prescription digital therapeutic for improving patient outcomes for users with GI health conditions.

Systems and methods are provided for monitoring a user having a chronic gastrointestinal indication. A questionnaire regarding a plurality of conditions is provided on a repeating basis. Each such condition at least partly arises from the gastrointestinal indication. Questionnaire questions are each associated with a corresponding condition and provide an affordance that allows the user to select between low and high values in accordance with user association with the condition. Responses are stored in a data store associated with the user. A user requested report comprising a graphical quality of life measure of the user is provided based upon temporal questionnaire answers. Questionnaire information is communicated to a remote device for medical practitioner evaluation and computation of a temporal overall quality of life score based on a plurality of component quality of life scores, each of which is associated with a condition in the plurality of conditions.

A method for operating an accessory device to capture calibration data. The method can include capturing an image of a portion of a user's body that includes the user's stoma and at least two reference locations, and storing distance scale information representative of a distance between the two reference locations. The method further includes processing the captured image, including: identifying the reference locations, identifying the stoma, and generating calibration data representative of one or more stoma parameters as a function of the identified reference locations, identified stoma and the distance scale information. The calibration data can be stored.

A swallowable in-vivo device comprising a shell formed with at least one inlet extending across a shell wall and configured for allowing ingress of fluid at least into the shell; the shell accommodates therein a lateral flow (LF) arrangement configured for absorbing the fluid; the LF arrangement comprises a test zone configured for coming into contact, in-vivo, with a predetermined N substance present in the fluid or a compound comprising the substance, thereby causing a change in at least one property of the test zone; the shell further accommodates a sensor configured for sensing, in-vivo, the at least one property, at least when changed by interaction with the fluid; the LF arrangement has at least one curved segment, and at least one exposure portion juxtaposed with the inlet, configured for absorbing the fluid passing through the inlet into the shell.

A system may include an expandable member, and a plurality of sensors disposed on an outer surface of the expandable member and circumferentially spaced apart from one another, wherein each of the plurality of sensors includes a first emitter configured to emit light of a first wavelength, and a detector configured to detect light, and a controller coupled to the plurality of sensors.

This disclosure features methods and compositions for treating diseases of the gastrointestinal tract with glatiramer or a pharmaceutically acceptable salt thereof, such as glatiramer acetate).

A system and a method for automatically and continuously measuring and assessing hemodynamics uses fluorescence imaging in which the fluorescent agent is controlled and automated. A method of automatic perfusion assessment of an anatomical structure of a subject includes administration into a vein of a bolus corresponding to less than 0.01 mg ICG/kg body weight of a first fluorescence imaging agent. A system for automatic perfusion assessment during a medical procedure includes a controllable injection pump for holding at least one first fluorescence imaging agent, the injection pump being configured for injecting a predefined amount of the first fluorescence imaging agent into the blood. The system is configured for receiving and analysing a time series of fluorescence images and determining at least one perfusion parameter based on the analysis.
