A gastrointestinal treatment system including a gastrointestinal capsule adapted to treat a subject following ingestion of the gastrointestinal capsule. The gastrointestinal capsule includes: (a) a housing; (b) a vibrating agitator, powered by the battery, the vibrating agitator adapted such that, in a first vibrating mode of operation, the housing exerts vibrations on an environment surrounding the capsule; (c) a power supply disposed within the housing and adapted to power the vibrating agitator; and (d) a controller adapted, in response to receipt of an activation input, to activate the vibrating agitator to operate in the first vibrating mode of operation at at least one predetermined time of day. The system and method may be used to treat an ailment of the gastrointestinal tract and/or to mitigate at least one symptom of jetlag in a subject travelling from an origin location to a destination location.

A system comprises an implantable medical device configured to generate temperature data and impedance data associated with temperature and impedance of a patient proximate to the implantable medical device. The system further comprises processing circuitry configured to determine whether a first one or more infection criteria are satisfied by temperature data and impedance data generated by the implantable medical device during a first time interval, wherein the first one or more infection criteria include at least one criterion indicative of decreased impedance, determine whether a second one or more infection criteria are satisfied by the temperature data and impedance data generated by the implantable medical device during a second time interval subsequent to the first time interval, wherein the second one or more infection criteria include at least one criterion indicative of increased impedance, and output, based on satisfaction of the first and second infection criteria, an indication of infection.

Example medical devices, including example stents and stent systems, are disclosed. An example stent includes an expandable tubular scaffold having a proximal end and a distal end, a first wire coupled to the tubular scaffold, wherein the first wire is shaped into a first coil. The example stent also includes a sensor electrically coupled to the first wire, wherein the sensor is inductively powered by a magnetic field passing through the first wire.

Assemblies are provided for positioning within a lumen comprising a stent graft; and a sensor positioned on the stent graft. Within certain aspects the sensors are wireless sensors, and include for example one or more fluid pressure sensors, contact sensors, position sensors, pulse pressure sensors, blood volume sensors, blood flow sensors, chemistry sensors (e.g., for blood and/or other fluids), metabolic sensors (e.g., for blood and/or other fluids), mechanical stress sensors and/or temperature sensors.

An implantable medical device (IMD), includes a processor for controlling the IMD; circuitry for providing therapeutic or diagnostic medical operations for a patient; wireless communication circuitry for conducting wireless communications; a non-rechargeable battery; and device power control circuitry. The device power control circuitry includes at least one capacitor; charging control circuitry for switching between charging the at least one capacitor using the non-rechargeable battery and discharging the at least one capacitor to provide power for device operations. The IMD is configured to maintain a count related to a number of times of discharge of the at least one capacitor to provide an end-of-life estimation for the non-rechargeable battery.

In one embodiment of the present disclosure, an ingestible medication device is a self-contained electronic device that stores an active agent, and that controls release of the active agent using an on board processor. The ingestible medication device embodies one or more ingestible device identifiers, including personal identifiers and active agent identifiers, which are compared with external device identifiers to determine whether to release the active agent. A method for managing an ingestible medication device detects proximity to a limited range, RFID-enabled patient wristband, indicating that the wristband is worn by the patient that ingested the ingestible medication device. Various methods enable a nurse to track medication information to monitor compliance with medication regimen and dosage information. Other methods track an ingestible medication device selected for filling a prescription at a pharmacy of the health care provider, including transfer to a caregiver station using a transport cart.

Transbody communication systems employing communication channels are provided. Various aspects include, for example, an in vivo transmitter to transmit an encoded signal; a transbody functionality module to facilitate communication of the encoded signal; and a receiver to receive the encoded signal. Methods and apparatus are also provided.

Disclosed is a radio antenna comprising a substrate of dielectric material; a ground plane of electrically conductive material on a first face of the substrate; a resonator for converting an incident electrical signal into an electromagnetic wave and for resonating at at least two different resonant frequencies. The resonator comprises at least three elements, each in the form of strips of conductive material and arranged on a second face of the substrate opposite the first face. A second element is electrically connected to the ground plane by means of a via passing through the substrate at a first end of the corresponding strip, forms an extension of the first element, and is electrically connected directly to the first element at a second end of said strip which is opposite the first end.

The invention relates to an active implantable medical device comprising a processing unit able to be alternately operated during a predetermined period of activity and on standby during a standby period in a cyclical manner, and means for acquiring data relating to physiological and/or physical activity. The device also comprises means for calculating a frequency analysis of the data acquired, said calculating means being capable of successively perform part of the frequency analysis during periods of activity of the processing unit.
