Abstract: Sensor systems can be used to measure an analyte concentration. Sensor systems can include a base having a distal side configured to face towards a person's skin. An adhesive can couple the base to the skin. A transcutaneous analyte measurement sensor can be coupled to the base and can be located at least partially in the host. A transmitter can be coupled to the base and can transmit analyte measurement data to a remote device.

Abstract: Disclosed are devices for determining an analyte concentration (e.g., glucose). The devices comprise a sensor configured to generate a signal associated with a concentration of an analyte and a sensing membrane located over the sensor. The sensing membrane comprises an enzyme layer, wherein the enzyme layer comprises an enzyme and a polymer comprising polyurethane and/or polyurea segments and one or more zwitterionic repeating units. The enzyme layer protects the enzyme and prevents it from leaching from the sensing membrane into a host or deactivating.

Abstract: The present disclosure relates to a needle including a wall structure, a cutting edge and a blunt contour. The needle advantageously can be used to deliver a sensor (such as a glucose or other analyte sensor) through an outer skin layer and into a sensor depth in a less invasive way than prior art needles. The size of the cutting edge is balanced against a portion of the distal wall structure that has blunt contours. Thus, the needle is capable of cutting the more durable outer skin layer (first phase) and then progressively stretching open the cut for further advancement into the subcutaneous layer (second phase). When the needle is sufficiently advanced, it is retracted leaving the sensor in a desired position. Early testing has shown a reduction of “dip and recover” from glucose sensors delivered using the needle.
