A capsule device and a method for the capsule device remain in a very low power state and monitor whether it enters a desired section of the gastrointestinal track. The capsule device is coated with an enteric material that is expected to dissolve after it enters the small bowel. In the monitoring state, the capsule device captures a first image using the camera and the light source at a first frame rate substantially below a target frame rate. The capsule device compares first information related to the first image with second information related to a coating image corresponding to the coating. If the first information does not matches the second information, the capsule device declares that the coating has dissolved and the capsule device configures the camera to capture third images at the target rate after declaring that the coating has dissolved.

An upper gastrointestinal bleeding monitoring system includes a detection device and a signal processing device to determine bleeding condition of an upper gastrointestinal tract by using relation of time and intensity ratios of RGB three primary colors. The detecting device is placed to the upper gastrointestinal tract of a patient via his/her mouth or nasal passage and then stay the upper gastrointestinal tract for several days for detection of bleeding. The signal processing device may receive and display signal from the detection device to help medical professionals check if bleeding occurs in an upper gastrointestinal tract. Moreover, a procedure of determination of bleeding in an upper gastrointestinal tract with the upper gastrointestinal bleeding monitoring system is described.

A system and method for monitoring a patient's compliance with a medication regimen includes an electronic tag having an antenna and a receiver/transmitter positioned with a medication capsule, and a reader positioned externally for detecting the presence and location of the tag in the patient.

Systems and methods are described for providing power transfer between modular intraluminal devices. A system embodiment includes, but is not limited to, a first intraluminal device and a second intraluminal device; the first intraluminal device including a body structure, a sensor, a processor, a data transmitter, and a wireless energy receiver oriented to wirelessly receive energy originating external to the first intraluminal device to power at least one of the sensor, the processor, or the data transmitter; the second intraluminal device including a second body structure, and an energy storage device configured to wirelessly transfer energy stored in the energy storage device to the wireless energy receiver of the first intraluminal device when the first intraluminal device and the second intraluminal device are positioned within a subject.

Systems and methods are described for providing power transfer between modular intraluminal devices. A system embodiment includes, but is not limited to, a first intraluminal device and a second intraluminal device; the first intraluminal device including a body structure, a sensor, a processor, a data transmitter, and an energy storage module configured to power at least one of the sensor, the processor, or the data transmitter; the second intraluminal device including a second body structure, an energy storage device, and a docking structure, where the energy storage device is configured to transfer energy when the first intraluminal device and the second intraluminal device are coupled via the docking structure, the docking structure further configured to automatically decouple the first intraluminal device and the second intraluminal device subsequent to transfer of the energy.

A body-mountable device is provided to facilitate communication, via in-body electrical signals transmitted via electrodes of the body-mountable device into fluid of the body, with a smart pill located in a gastrointestinal tract of a body to which the body-mountable device is mounted or with some other device located within the body. The body-mountable device can be a contact lens or other eye-mountable device such that the electrodes of the eye-mountable device can transmit in-body electrical signals via tear fluid. The body-mountable device could transmit a command to the smart pill to dispense a drug into the body. The smart pill could transmit, via in-body electrical signals, an indication of a detected property of the gastrointestinal tract to the body-mountable device. A latency of transmission of signals between the body-mountable device and the smart pill could be used to determine the location of the smart pill within the gastrointestinal tract.

The present invention relates to miniature biosensor technology which can be directly embedded into medical device technology to create a new category of multifunctional smart medical devices. The resulting data from these smart medical devices results in wireless communication networks and standardized referenceable databases, which are used in the creation of best practice guidelines, clinical decision support tools, personalized medicine applications, and comparative technology assessment.

Devices and methods for treating obesity are provided. More particularly, intragastric devices and methods of tracking and locating the same are provided.

A position detection system includes: an object to be detected having a magnetic field generator to generate a position detecting magnetic field, and configured to be introduced into a subject; detection coils, each being configured to detect the position detecting magnetic field to output a detection signal; and a processor including hardware. The processor is configured to: correct measured values of detection signals output from the detection coils using a magnetic field generated by applying the position detecting magnetic field to a metal plate, the metal plate being disposed on a side opposite to an area to be detected of the object to be detected relative to the detection coils; and calculate at least one of a position and a direction of the object to be detected using the corrected measured values of the detection signals.

Methods and systems for manufacturing a swallowable sensor device are disclosed. Such a method includes mechanically coupling a plurality of internal components, wherein the plurality of internal components includes a printed circuit board having a plurality of projections extending radially outward. A cavity is filled with a potting material, and the mechanically coupled components are inserted into the cavity. The cavity may be pre-filled with the potting material, or may be filled after the mechanically coupled components have been inserted therein. A distal end of each projection abuts against a wall of the cavity thereby preventing the potting material from covering each distal end. The cavity is sealed with a cap causing the potting material to harden within the sealed cavity to form a housing of the swallowable sensor device, wherein the distal end of each projection is exposed to an external environment of the swallowable sensor device.
