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.

The present invention relates to the process of using signal-emitting and/or receiving objects or smart medical devices for image acquisition, and which can utilize a variety of external energy sources which are directly applied and/or incorporated into the host subject to produce a continuous and dynamic visual representation of the host subject on a computer display, which representation hereafter will be referred to as a visualization map. The derived images can be targeted, to small (i.e., focal) areas of clinical interest, to organ systems, or the entire body. The present invention provides a scalable method for continuous and dynamic imaging over prolonged periods of time, as dictated by the clinical context.

A system and method for monitoring a health status of a subject. The system comprises: a medical device implantable in the subject and having a passage or compartment through which blood flows through; a sensor device embedded at or near a surface of said passage within said medical device for generating signals suitable for measuring a Doppler shift effect occurring within said passage; and a control device coupled to said sensor device for measuring a liquid blood flow rate within said passage based on sensor generated signals outputs. The embedded sensor device comprises a first piezo-electric element configured to generate an acoustic excitation signal and a second piezo-electric element configured to receive said acoustic excitation signal. The second piezo-electric element emits a signal responsive to said acoustic excitation signal. Control device in real time compares a generated output signal with the input excitation signal to determine a Doppler frequency shift measurement.

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.

For fixedly implanting a device for material or signal delivery or acquisition or a part of such a device in a human or animal body, an opening is provided in hard tissue of the body, the opening reaching through a hard tissue layer, e.g. through a cortical bone layer into cancellous bone underneath. The device includes a plug portion and/or a cover portion which includes a ring of a material having thermoplastic properties extending around the plug portion or on a tissue facing surface of the cover portion. The opening provided in the hard tissue has a cross section at least in the area of its mouth that is adapted to the plug or cover portion such that the plug portion can be introduced through the mouth of the opening or the cover portion can be positioned over the mouth of the opening such that the ring extends around the opening, along its wall and/or on the hard tissue surface around its mouth.

A capsule endoscope system including: a capsule endoscope including an imaging sensor configured to capture an image of inside of a subject at a changeable imaging frame rate and generate an image signal, and an image transmitter configured to transmit a wireless signal including the image signal; and a receiving device including a first and a second antennas configured to receive the wireless signal, a receiver configured to detect a first reception intensity and a second reception intensity, a controller configured to generate a first instruction signal that changes the imaging frame rate to a first value higher than an initial value that is set in advance when the first or the second reception intensity satisfies a predetermined condition, and a transmitter configured to wirelessly transmit the first instruction signal to the capsule endoscope.

A device and methods for using a device, for determining a passing of flatus is described. The device comprises a sleeve comprising a first porous gas-permeable surface, a second surface attached to the first porous gas-permeable surface defining a pocket within the sleeve, and a flatus detector inserted within the pocket of the sleeve and positioned between the first porous gas-permeable surface and the second surface. The flatus detector may be a dry-surface carbon dioxide detector that irreversibly changes colour upon contact with increased concentrations of CO.sub.2 gas, a chemiresistor, or a near field communication tag. The chemiresistor or near field communication tag may be modified for detecting target gases. The device may be a patch that is affixed to a patient or attached to a garment that is worn by the patient, or a capsule, with a detector disposed therein.

An ingestible bolus for automatically monitoring location and physiological parameters including core temperature of ruminant animals. The location parameters are determined using magnetic field information and/or GPS data sensed by the sensors in the bolus and communicated along with a unique ID number and time stamp to a centralized location. A data center at the centralized location comprises a computing environment for analyzing the data received from the bolus and transfer the analyzed results including animal temperature, location to a user interface display. The temperature information is analyzed at the data center to determine the health status of the animal.
