An analyte monitor includes a sensor, a sensor control unit, and a display unit. The sensor has, for example, a substrate, a recessed channel formed in the substrate, and conductive material disposed in the recessed channel to form a working electrode. 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. The analyte monitor may also be part of a drug delivery system to alter the level of the analyte based on the data obtained using the sensor.

Analyte Monitoring Device And Methods Of Use

A telemetered characteristic monitor system includes a remotely located data receiving device, a sensor for producing signal indicative of a characteristic of a user, and a transmitter device. The transmitter device includes a housing, a sensor connector, a processor, and a transmitter. The transmitter receives the signals from the sensor and wirelessly transmits the processed signals to the remotely located data receiving device. The processor coupled to the sensor processes the signals from the sensor for transmission to the remotely located data receiving device. The data receiving device may be a characteristic monitor, a data receiver that provides data to another device, an RF programmer for a medical device, a medication delivery device (such as an infusion pump), or the like.

Telemetered characteristic monitor system and method of using the same

A body fluid sampling system for use on a tissue site includes a single drive force generator. A plurality of penetrating members are operatively coupled to the force generator. The force generator moves each of the members along a path out of a housing with a penetrating member exit, into the tissue site, stops in the tissue site, and withdraws out of the tissue site. A flexible support member couples the penetrating members to define a linear array. The support member is movable and configured to move each of the penetrating members to a launch position associated with the force generator.

A tissue penetration device and method of using same. The tissue penetration device may optionally include sampling and analyzing functions, which may be integrated. An embodiment provides control of a lancet used for sampling blood. Electric field coils or solenoids may drive the lancet using electromagnetic force. Advancement and retraction of a lancet may be controlled by a feedback loop monitoring the position and velocity of the lancet embodiments of the lancet driver can be configured to follow a predetermined tissue lancing profile. Embodiments of the invention include a lancet and method for using a lancet to maintain the patency of the wound tract once the lancet has cut into the skin.

Tissue penetration device

Systems and methods for integrating a continuous glucose sensor, including a receiver, a medicament delivery device, and optionally a single point glucose monitor are provided. Manual integrations provide for a physical association between the devices wherein a user (for example, patient or doctor) manually selects the amount, type, and/or time of delivery. Semi-automated integration of the devices includes integrations wherein an operable connection between the integrated components aids the user (for example, patient or doctor) in selecting, inputting, calculating, or validating the amount, type, or time of medicament delivery of glucose values, for example, by transmitting data to another component and thereby reducing the amount of user input required. Automated integration between the devices includes integrations wherein an operable connection between the integrated components provides for full control of the system without required user interaction.

Integrated delivery device for continuous glucose sensor

The systems of the present invention include a medication infusion pump (4) and a hand-held 'fob' (6) for the remote control of the infusion pump and/or measurement device (300). In addition to remotely controlling the insulin pump and the measurement device, the fob provides for the consolidation of blood chemistry data and insulin delivery data over a period of time and maintains such consolidated data for immediate and later retrieval by the user or a physician.

Systems and methods for remotely controlling medication infusion and analyte monitoring

Devices, systems and methods are provided for remotely controlling
medication delivery to a patient by means of a medication infusion pump, such as a
subcutaneous infusion pump, and for remotely controlling the monitoring of one or
more physiological fluid analytes such as by a percutaneous measurement device. The
systems of the present invention include a medication infusion pump and a hand-held
"fob" for the remote control of the infusion pump and/or measurement device. In
addition to remotely controlling the insulin pump and the measurement device, the fob
provides for the consolidation of blood chemistry data and insulin delivery data over a
period of time and maintains such consolidated data for immediate and later retrieval
by the user or a physician. The methods of the present invention allow a user to
customize and optimize an insulin bolus delivery protocol, i.e., bolus volume and
delivery duration, by factoring in or compensating for the user's current or substantially
current blood chemistry evaluation and/or the user's anticipated and/or actual
carbohydrate intake.

Systems for remotely controlling medication infusion and analyte monitoring

The present invention relates to a method for wireless transmission of data between components of a blood glucose system (1, I1) including a master controller (2, 2') having a receiver (10) and a transmitter (9), and at least one slave device (3) having a receiver (19) and a transmitter (18), and to a corresponding blood glucose system (1, I1) • The slave device (3) is normally operated in a power saving mode in which its receiver (19) is only activated intermittently at a receiver activation frequency for a predetermined listening period The controller (2, 21) transmits a communication initiation data frame to the slave device (3) by means of a signal comprising a preamble signal transmitted for a preamble period Upon receipt of the communication initiation data frame, the slave device (3) is switched to a communication mode in which it transmits a response to the controller (2, 21), and the slave device (3) is switched from the communication mode to the power saving mode Initially the receiver activation frequency is set to a first frequency value upon switching from communication mode to power saving mode, and then to a second frequency value smaller than the first frequency value if no communication initiation data frame is received for a predetermined power saving timeout period The communication initiation data frame is transmitted such that the preamble period exceeds the length of the cycle duration corresponding to the first frequency value, and, in case no response is received by the controller during the response period, the communication initiation data frame is adapted and retransmitted such that the preamble period is increased and exceeds the length of the cycle duration corresponding to the second frequency value
