The invention refers to an implantable sensing system comprising an electronic implant and a reading unit to obtain measurements originating at the implant or its surroundings to characterize physical and/or chemical clinical parameters of a living body. The electronic implant comprises an electronic circuit and at least two electrodes connected to the electronic circuit. The electronic circuit comprises a capacitor and a device of asymmetric conductance capable of rectifying an alternating current, both connected in series between two electrodes. An electronic component is connected in parallel with the device of asymmetric conductance, for the capacitor discharge. The capacitor, the device of asymmetric conductance and/or the electronic component, can be a transducer selected such as an operational parameter of the transducer is variable depending on a physical and/or chemical condition of a medium of a living body. The implant features a minimal invasiveness, such as it can be implanted by injection or by catheterization rather than by open surgery.

Medical implants including sensors are described. The implant may have a flexible shell with a base, wherein the plurality of sensors may be incorporated onto and/or into the shell. The plurality of sensors may be distributed at different locations of the shell. Each sensor of the plurality of sensors may be configured to measure one or more parameters such as, e.g., temperature and/or pressure, and may comprise an electromagnetic coil useful for wireless transmission of data. Each sensor may be configured to transmit data at a frequency different from the frequency of one or more of the other sensors, may be configured to transmit data at a time different from a time data is transmitted by one or more of the other sensors, and/or may include a device identifier different from the device identifier of one or more of the other sensors.

An ingestible capsule for detecting cancerous and non-cancerous tissues in a colon of patient is disclosed. The capsule has a radiation source integrated into the capsule body for illuminating tissues within a colon of the patient. Tissues of the colon are irradiated with radiation from the radiation source to elicit a fluorescence response, and a photon detector measures photons of the fluorescence response. Intensity and fluorescence lifetime of the fluorescence response is determined based on measured photons. A system employing the capsule is configured to distinguish cancerous and non-cancerous tissues based on the determined fluorescence lifetime of the fluorescence response.

A system and a method for treatment of a disorder in a gastrointestinal tract of a subject, using a treatment protocol, the treatment protocol being based at least in part on data relating to other subjects and their responses to treatment with various treatment protocols.

A computerized-method for a mucosal assessment of a mucosal disease in a Gastrointestinal Tract (GIT) of a subject, including receiving a stream of images of at least a portion of the GIT, parsing the stream into a plurality of segments, wherein each segment corresponds to a region of the at least portion of the GIT, obtaining a set of values for each segment, wherein the set of values refers to the pathological involvement of the segment in the mucosal disease and to severity of mucosal manifestation of the mucosal disease in the segment, and based on said set of values for each segment, generating a representation indicating the location and severity of the mucosal manifestation of the mucosal disease in the entirety of the at least portion of the subject's GIT, thereby allowing to assess the condition of the mucosal disease in the at least portion of the GIT.

Various embodiment disclosed herein include a method for monitoring serum potassium in a patient. The method can include gathering cardiac electrogram data from the patient using two or more electrodes, separating the cardiac electrogram data into discrete subunits including a T-wave, aligning T-waves to create aligned discrete subunits, averaging the aligned discrete subunits to generate an average T-wave for the cardiac electrogram data, and determining a serum potassium value using the average T-wave for the cardiac electrogram data and a predetermined model relating T-wave values with serum potassium magnitudes.

An imaging system includes a tether, a tapered end portion coupling the tether to an imaging capsule, the imaging capsule comprising a camera lens, and at least one fluid wicking element, positioned on the imaging system proximate to the camera lens of the imaging capsule to enable the fluid wicking element to wick liquid away from the camera lens. In some embodiments, the fluid wicking element of the imaging system further functions as an alignment element for the imaging system to enable a positioning of the imaging system in an opening.

Implantable device for measuring the glucose concentration of a body fluid when implanted, the implantable device comprising a glucose measurement unit, the glucose measurement unit comprising a first light source configured to emit light towards a light transmissive part of a housing of the device and a first optical sensor configured to detect light returned through the light transmissive part from the first light source, and output a first electrical signal based on the detected light; and a wireless communication module configured to wirelessly communicate with an external wireless communication device, wherein the wireless communication module is configured to wirelessly transmit a signal based on the first electrical signal to the external wireless communication device.

In one embodiment, a sensor includes a capsule having a cavity and a sheath, a transducer coupled to electronic circuitry in the cavity, and a clip outside the capsule. The capsule and the clip are configured to hold in vivo an object within an opening between the capsule and the clip. The transducer is configured to detect an incoming signal indicative of a physiological parameter of the object being held, and the electronic circuitry is configured to wirelessly transmit a signal containing information about the physiological parameter obtained from the incoming signal. The sensor is part of a measurement system to measure the physiological parameter. Another embodiment describes a method using the measurement system.
