  • Oxygen enhancing membrane systems for implantable devices
    Patent number: 10610140
    Abstract: The present invention relates generally to systems and methods for increasing oxygen availability to implantable devices. The preferred embodiments provide a membrane system configured to provide protection of the device from the biological environment and/or a catalyst for enabling an enzymatic reaction, wherein the membrane system includes a polymer formed from a high oxygen soluble material. The high oxygen soluble polymer material is disposed adjacent to an oxygen-utilizing source on the implantable device so as to dynamically retain high oxygen availability to the oxygen-utilizing source during oxygen deficits. Membrane systems of the preferred embodiments are useful for implantable devices with oxygen-utilizing sources and/or that function in low oxygen environments, such as enzyme-based electrochemical sensors and cell transplantation devices.

  • Systems and methods for processing analyte sensor data
    Patent number: 10588557
    Abstract: Systems and methods for applying time-dependent algorithmic compensation functions to data output from a continuous analyte sensor. Some embodiments determine a time since sensor implantation and/or whether a newly initialized sensor has been used previously, for example, by initializing a sensor, acquiring sensor data, using the sensor, to measure an analyte level in the host's body over a first interval based on a first elapsed time since the sensor was implanted, determining whether the sensor has been previously used in a previous sensor session or the sensor is a new sensor, and upon determining the sensor is a new sensor, adjusting the acquired sensor data to compensate for sensor drift of the new sensor by applying a first set of time-dependent algorithmic functions to the sensor data associated with the first interval.
