摘要:
A device and method for delivering a device such as a sensor or fluid transport structure or a fluid transport structure sensor combination into, for example, animal skin. Such a device utilizes an introducer device such as a needle or trocar to puncture skin and allow a sensor to enter through the resultant skin puncture. A device in accordance with embodiments of the present invention includes a housing for mounting to animal skin including an opening for receiving both the distal end of an analyte sensor and the end of an introducer, an actuator device for forcing the introducer from a first position within the housing, through the exit port to a second position, with sufficient force to puncture skin.
摘要:
A multi-conductor cable including a plurality of miniature coaxial conductor pairs, each including an inner conductor supported by a very thin tubular layer of solid, relatively stiff dielectic material, surrounded by a much thicker wrapping of dielectric tape having a lower dielectric constant than that of the tubular layer. An outer conductor of multiple strands of wire is helically laid about the dielectric tape wrapping. The tubular layer provides mechanical support for each inner conductor, protecting against breakage due to bending of the individual conductor strands, without significantly increasing either the capacitance or diameter of the coaxial conductor pairs.

Embodiments provide analyte sensors, such as implantable analyte sensors, and methods of producing the same. An implantable sensor may include a base with a plurality of chambers. One or more sensor reagents may be retained within the chambers to form analysis regions. A membrane may be coupled to the chambers over the sensor reagents. The implantable sensor may be implanted into the dermis of a subject. One or more of the sensor reagents may exhibit a color change in response to the presence of a target analyte or reaction product thereof. The wavelengths of light reflected from the analysis regions may be detected and analyzed to determine a target analyte concentration. One or more portions of the sensor or components thereof may be configured to facilitate calibration of the sensor, correction of an optical signal obtained from the sensor by a reader device to accommodate variations in the surrounding tissues, and/or calculation of a representative value by a reader device.
摘要:
A sensing element adapted to, at least in part, be inserted into a mammalian body. The sensing element is made up of a core of a structurally robust metal and a plated portion made of an electrochemically active metal conjoined to at least a portion of the core. This sensing element may be used as part of a method for the continuous or intermittent monitoring of an analyte within a mammalian body. The method includes inserting at least a portion of the sensing element into the mammalian body and measuring any electric current produced by at least of portion of the sensor.
摘要:
A method of measuring an analyte concentration in body fluid in an animal body having skin and subcutaneous soft tissue that includes body fluid. The method comprises, introducing a portion of an analyte-measuring device into the subcutaneous soft tissue. The analyte-measuring device includes an analyte sensing element, having a sharpened distal end to facilitate introduction into the animal body. Additionally the sensing element has an indicating electrode that is adapted to be activated by electric power and to form a raw analyte measurement, when it is activated and in contact with the body fluid, in less than two minutes. The sensing device further has a reference electrode and an electric power and display device that is adapted to mate to the analyte-sensing element. The power and display device activates the analyte-sensing element by applying electric power to it. The analyte-sensing element is introduced into the animal body and is activated by the electric power and display device, thereby causing the analyte-sensing element to form a raw analyte measurement. The power and display device forms and displays a second analyte measurement that is related to the raw analyte measurement, within two minutes of the analyte sensing element being introduced into the body.
