  • Intragastric device
    Patent number: 10327936
    Abstract: An implant configured for ingestion by a patient. After the implant has been swallowed by the patient and is disposed within the target location, e.g. the patient's stomach, an inflation subcomponent causes the implant to expand from a compact delivery state to an expanded, volume-occupying, deployed state. In the deployed state the implant creates a sensation of satiety in the patient stomach and thereby aids in limiting food intake and obesity. After a predetermined time a deflation subcomponent is actuated and the implant reduces in size so as to allow it to pass through the remainder of the patient's digestive track. The device may further incorporate tracking and visualization subcomponents, as well as pharmaceutical delivery subcomponents.

  • INTRAGASTRIC DEVICE
    Publication number: 20170079821
    Abstract: An implant configured for ingestion by a patient. After the implant has been swallowed by the patient and is disposed within the target location, e.g. the patient's stomach, an inflation subcomponent causes the implant to expand from a compact delivery state to an expanded, volume-occupying, deployed state. In the deployed state the implant creates a sensation of satiety in the patient stomach and thereby aids in limiting food intake and obesity. After a predetermined time a deflation subcomponent is actuated and the implant reduces in size so as to allow it to pass through the remainder of the patient's digestive track.

  • INTEGRATED RECEIVER FOR CONTINUOUS ANALYTE SENSOR
    Publication number: 20170055889
    Abstract: A system is provided for monitoring glucose in a host, including a continuous glucose sensor that produces a data stream indicative of a host's glucose concentration and an integrated receiver that receives the data stream from the continuous glucose sensor and calibrates the data stream using a single point glucose monitor that is integral with the integrated receiver. The integrated receiver obtains a glucose value from the single point glucose monitor, calibrates the sensor data stream received from the continuous glucose sensor, and displays one or both of the single point glucose measurement values and the calibrated continuous glucose sensor values on the user interface.
