  • Patent number: 9307938
    Abstract: An implantable product such as an article, device, or system can include analyte and non-analyte containers in parts that can be operated as optical cavities. The product can also include fluidic components such as filter assemblies that control transfer of objects that affect or shift spectrum features or characteristics such as by shifting transmission mode peaks or reflection mode valleys, shifting phase, reducing maxima or contrast, or increasing intermediate intensity width such as full width half maximum (FWHM). Analyte, e.g. glucose molecules, can be predominantly included in a set of objects that transfer more rapidly into the analyte container than other objects, and can have a negligible or zero rate of transfer into the non-analyte container; objects that transfer more rapidly into the non-analyte container can include objects smaller than the analyte or molecules of a set of selected types, including, e.g., sodium chloride.

  • Publication number: 20080015425
    Abstract: A sampling device for sampling body fluid includes a lancet for making an incision, a capillary tube for drawing-up body fluid from the incision, and a test strip affixed to an upper end of the capillary tube for receiving the fluid. An absorbent pad can be disposed between the test strip and capillary tube for spreading-out the fluid being transferred to the test strip. An on-site analyzer such as an optical analyzer and/or an electrochemical analyzer can be mounted in the device for analyzing the fluid. Alternatively, a test strip can be slid through a slot formed in the bottom end of the device so that by passing the device against the skin after an incision has been formed, the test strip will directly contact body fluid emanating from the incision.

  • Publication number: 20070106178
    Abstract: An integrated lancing test strip includes a pair of blade members that each have a lancing tip that are configured to lance skin. A pair of spacer members connect the blade members together such that the blade members define an internal capillary. A test strip is positioned along the internal capillary, and the test strip is configured to test analyte levels in the bodily fluid. During use, the lancing tips form one or more incisions in the skin. The fluid from the incisions is drawn via capillary action through the internal capillary and onto the test strip.

  • Publication number: 20070093728
    Abstract: A device and method for lancing a patient, virtually simultaneously producing and collecting a small fluid sample from a body. The device comprises a blood collection system including a lancing needle (16), drive mechanism (11), kneading or vibration mechanism (25), optional suction system (7), and sample ejection mechanism. The device is preferably sized to be hand-held in one hand and operable with one hand. The device can optionally contain integral testing or analysis component (83) for receiving the sample and providing testing or analysis indication or readout for the user. A method involves piercing the skin at a rapid rate, kneading the surrounding area by ultrasonic action, piezoelectric or mechanical oscillation to stimulate the blood flow from the wound, drawing the fluid using a pumping system.

  • Publication number: 20070038126
    Abstract: A method is provided of measuring in vivo of an endogenous fluorophore in a tissue site. A known excitation wavelength of the endogenous flurophore is selected within a range of wavelengths at which the endogenous flurophore undergoes fluorescence. The tissue site is irradiated with irradiated light having at least the selected excitation wavelength within the range of wavelengths. A fluorescence emission of the tissue site resulting from the irradiation thereof is detected. A relative or absolute concentration of the endogenous fluorophore is determined by multiplying it by a calibration factor that depends one at least one of, a known excitation and emission property of the endogenous fluorophore, an intensity of the irradiated light, optical properties of an excitation probe, and specific properties of the tissue. The relative or absolute concentration of the endogenous fluorphore is used to estimate at least one of a, in vivo cellular energy production status or state of end-organ tissue oxygenation.

  • Publication number: 20060155316
    Abstract: A sample of a body fluid such as blood or interstitial fluid is obtained from a body by lancing a portion of a user's skin, preferably in an area other than a finger tip, to form an incision. After the needle has been removed from the incision, a force is applied to depress the skin in a manner forming a ring of depressed body tissue in surrounding relationship to the incision, causing the incision to bulge and the sides of the incision to open, whereby body fluid is forced out through the opening of the incision. A stimulator member is mounted to an end of a lancet-carrying housing for applying the force. The stimulator member can be movable relative to the housing, and can be either heated or vibrated to promote movement of the body fluid.

  • Publication number: 20060088945
    Abstract: An electrochemical test device is provided for determining the presence or concentration of an analyte in an aqueous fluid sample. The electrochemical test device includes a working electrode and a counter electrode made of an amorphous semiconductor material. The working electrode is overlaid with a reagent capable of reacting with an analyte to produce a measurable change in potential which can be correlated to the concentration of the analyte in the fluid sample. The test device optionally contains a reference electrode made of an amorphous semiconductor material having a reference material on the reference electrode. The test device electrodes can be constructed on a flexible film substrate, such as a polymeric film or a metal foil coated with a non-conductive coating.

  • Publication number: 20060079811
    Abstract: A bodily fluid sampling device includes a piercing device and a sensor enclosed in a housing. A cassette, which contains test media, is positioned proximal to the sensor so that the sensor is able to analyze a bodily fluid sample collected on the test media. The cassette includes a supply portion from which unused test media is supplied and a storage portion in which contaminated test media is stored after exposure to the bodily fluid. The cassette is adapted to collect a series of bodily fluid samples without requiring disposal of the test media.

  • Publication number: 20050283094
    Abstract: A body fluid testing device includes a test strip, an incision forming member, and a housing. The test strip includes an expression surface. In addition, the test strip is attached to the housing to form a cavity, and the cavity slidably receives the incision forming member. The body fluid testing device is positioned over the incision site where the incision forming member makes an incision. The user presses the expression surface against the skin to express body fluid. The cavity collects body fluid via capillary action, and the test strip analyzes the body fluid.

  • Publication number: 20050251064
    Abstract: An integrated sampling device defines a first opening and a second opening. The first opening is connected to a channel for drawing fluid automatically towards a test media upon incision by an incision portion. The second opening is positioned over the test media allowing manual sampling of fluid if the channel fails to draw a sufficient amount of fluid onto the test media.

  • Publication number: 20050025195
    Abstract: A data detection system includes, in part, a CID detector, a DC balance monitor and a transition density detector. The CID detector is configured to detect whether the received data stream includes a CID exceeding a predetermined threshold count. The DC balance monitor is configured to detect DC imbalances in the incoming data and that may be indicative of errors in the data. The transition density detector is configured to detect whether a minimum transition density exists during a given time period. If a violation is detected by any one of these three detectors, an out-of-frame signal is asserted. The incoming data stream may be a scrambled SONET or SDH data stream.
