摘要： A method for monitoring a cardiovascular pressure in a patient includes measuring, by pressure sensing circuitry of an implantable pressure sensing device, the cardiovascular pressure of the patient. The method further includes transmitting, via wireless communication circuitry of the implantable pressure sensing device, the measured cardiovascular pressure to another device. The method further includes determining, by processing circuitry of the other device, whether a posture of the patient at a time of the measured cardiovascular pressure was a target posture for cardiovascular pressure measurements. The method further includes determining, by the processing circuitry of the other device, whether to store or discard the transmitted cardiovascular pressure based on determining whether the posture was the target posture.

摘要： Systems for liquid biopsy and/or drug delivery may include a capsule endoscope and a tether coupled to the capsule endoscope. The tether may include a flexible member with a lumen in fluidic communication with a port configured to permit passage of fluid, and the port may be, for example, on the capsule endoscope or the tether. In methods for liquid biopsy and/or drug delivery, the capsule endoscope may be advanced into a gastrointestinal tract of a patient, and navigated to a region of interest, where a patient sample may be withdrawn and/or a therapeutic substance may be administered through the lumen (e.g., through the port).

摘要： A medical temperature monitoring system includes an electrical wire set having a thermistor at a distal end of the wire set configured to sense temperatures to which the thermistor is exposed; an electronic circuit in electrical communication with the wire set and the thermistor and configured to convert the temperatures sensed by the thermistor to temperature display signals; a display in electrical communication with the electronic circuit for receiving the temperature display signals and displaying temperatures corresponding to the temperature display signals; and a bead of cured protective material encapsulating the thermistor. The protective material is a radiation curable adhesive applied to the thermistor in an uncured state and then cured to encapsulate the thermistor. The bead of cured protective material electrically isolates the conductor sufficient to pass a Hi-Pot test at 500 VAC,

摘要： The present invention provides a capsule for fluid sampling and drug delivery including: an enclosure; a sampling/drug delivery assembly, including a storage chamber arranged in the enclosure, a first one-way element and a second one-way element communicating with outside of the capsule and the storage chamber, and a pump changing pressure in the storage chamber, wherein the first one-way element and the second one-way element have same direction of access; and a control module, including a microprocessor in communication with the pump. The capsule can realize multiple times of sampling and drug delivery by means of control flow direction of sample or drug through the first one-way element and the second one-way element, and by changing the pressure of the storage chamber through the pump.

摘要： An aspect of an embodiment of the invention, relates to an imaging capsule for scanning inside a living body with a fail-safe radiation mechanism that prevents the emission of radiation from the imaging capsule until the imaging capsule is instructed to emit radiation and power is available to activate a motor to unblock the emission of radiation. Optionally, when power is not available the imaging capsule automatically, blocks the emission of radiation.
