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 surgical instrument with a programmable control unit and methods for programming the control unit while the surgical instrument is in a sterile container. The method may comprise packaging the surgical instrument in the container and then sterilizing the surgical instrument while the surgical instrument is in the container. The method may further comprise programming the surgical instrument while the surgical instrument is in the container with a programming device positioned outside of the container.

Methods and systems for providing data communication in medical systems are disclosed including a data communication unit to transmit one or more signals related to the monitored analyte level received from the analyte sensor to a remote device.

Analyte monitoring system and methods

The invention relates to a method for calibrating an analyte-measurement device that is used to evaluate a concentration of analyte in bodily fluid at or from a measurement site in a body. The method involves measuring a concentration, or calibration concentration, of an analyte in blood from an “off-finger” calibration site, and calibrating the analyte-measurement device based on that calibration concentration. The invention also relates to a device, system, or kit for measuring a concentration of an analyte in a body, which employs a calibration device for adjusting analyte concentration measured in bodily fluid based on an analyte concentration measured in blood from an “off-finger” calibration site.

A wireless communication system is provided that includes an antenna structure adapted for coupling to a medical device antenna when the medical device is not implanted in a patient's body. The antenna structure effectively extends the medical device antenna length, thereby improving the efficiency and reliability of a communication link between the medical device and a programmer or monitor outside the implanted environment. The antenna structure is fabricated from any conductive material, which may be in the form of conductive wire, tape, ink, foil, film, adhesive or the like, and is attached to a portion of a medical device packaging assembly or another accessory device or substrate such as a pouch or overlay. The antenna structure may be a monopole, dipole, slot antenna, microstrip patch, or loop antenna, and may be fixed or movable relative to the substrate on which it is implemented.

Implantable medical device package antenna

An implantable medical device is provided including a housing, an external circuit element extending outwardly from the housing, an internal circuit enclosed by the housing, a feedthrough array disposed along the housing having at least one filtered feedthrough and at least one unfiltered feedthrough, wherein the unfiltered feedthrough is adapted for connection to the outwardly extending circuit element; and including means for minimizing electromagnetic coupling between the filtered feedthrough and the unfiltered feedthrough.

A wireless data communication card configured in accordance with an example embodiment of the invention includes a low profile antenna arrangement that does not protrude from the housing of the computing device when the wireless data communication card is inserted into the housing. The low profile design is achieved without compromising the radio frequency (“RF”) characteristics and performance of the wireless data communication card by tuning the antenna arrangement to account for conductive ground structure located within the housing of the computing device. In accordance with one practical embodiment of the invention, the wireless data communication card is compliant with IEEE Standard 802.11(b) and compliant with PCMCIA specifications.

A telemetry component according to an embodiment of the invention, such as a programmer or a monitor for an implantable medical device (“IMD”), includes at least one radio frequency (“RF”) antenna that is configured to accommodate far-field telemetry between the telemetry component and the IMD The RF antenna is shaped, sized, positioned, and otherwise configured to account for surface current cancellation caused by induced surface current on an electrically conductive surface of the telemetry component

Compact conformal antenna for a medical telemetry system

An implantable medical device (“IMD”) configured in accordance with an example embodiment of the invention generally includes a housing, a connector header block coupled to the housing, and a telemetry antenna located within the header block. The header block is formed from a dielectric material, which encapsulates the antenna. The antenna is configured to support far field telemetry with an external device such as a programmer. In one example embodiment, the antenna is formed from a thin round wire, has a feed point on the top perimeter sidewall of the housing, and has a floating endpoint in the header block. The antenna is contoured to form a simple curve in a plane that is approximately parallel with the major sides of the housing.
