`
`An analyte monitor includes a sensor, a sensor control unit,
`and a display unit. The sensor control unit typically has a
`housing adapted for placement on skin and is adapted to
`receive a portion of an electrochemical sensor. The sensor
`control unit also includes two or more conductive contacts
`disposed on the housing and configured for coupling to two
`or more contact pads on the sensor. A transmitter is disposed
`in the housing and coupled to the plurality of conductive
`contacts for transmitting data obtained using the sensor. The
`display unit has a receiver for receiving data transmitted by
`the transmitter of the sensor control unit and a display
`coupled to the receiver for displaying an indication of a level
`of an analyte, such as blood glucose. An inserter having a
`retractable
`introducer
`is provided for subcutaneously
`implanting the sensor in a predictable and reliable fashion.
