Abstract
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.

2. A transcutaneous system for measuring an analyte concentration in a host, the system comprising:
-
a sensor adapted for transcutaneous insertion through a skin of a host; a subassembly comprising a mounting unit adapted for placement adjacent to the skin of the host and an electronics unit configured to be releasably attachable to the mounting unit, wherein the subassembly is configured such that the mounting unit and the electronics unit are located over an exit site of the sensor when the sensor is inserted through the skin of the host; and an applicator comprising a needle configured to receive the sensor, wherein the applicator comprises a plunger configured to push the needle and the sensor through the mounting unit and subsequently retract the needle into the applicator, thereby leaving the sensor in the host. - View Dependent Claims (3, 4, 5, 6, 7, 8, 9, 10, 11)

19. An applicator system for inserting a transcutaneous sensor into a host, the applicator comprising:
-
a sensor configured for transcutaneous placement through a skin of a host; a needle configured for inserting the sensor into the host, wherein the sensor is disposed in the needle prior to insertion into the host; a subassembly comprising a housing adapted for placement adjacent to the skin of the host and an electronics unit releasably attachable to the housing; and an applicator configured for inserting the needle and the into the skin of the host, wherein the needle and the sensor are disposed within the applicator prior to insertion of the sensor; wherein the applicator is configured to insert the needle and the sensor into the skin of the host to leave the sensor transcutaneously placed within the host, and wherein the applicator is configured such that it must be released from the housing in order to allow the electronics unit to be attached to the housing. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27)
