Abstract:
In one embodiment according to the present invention, a device is provided comprising a cartridge having a plurality of cavities. The device may include a plurality of penetrating members at least partially contained in the cavities of the single cartridge wherein the penetrating members are slidably movable to extend outward from lateral openings on the cartridge to penetrate tissue. The device may have a sterility barrier coupled to the cartridge, wherein the sterility barrier covers a plurality of the lateral openings, and wherein the sterility barrier covering the lateral openings is configured to be moved so that a penetrating member exits the lateral opening without contacting the barrier. The device may include a plurality of analyte detecting members coupled to the cartridge and a plurality of sample capture devices, wherein the sample capture devices each having an opening there through to allow a penetrating member to pass through.
Abstract:
A system for extracting a bodily fluid sample (e.g., an interstitial fluid nullISFnull sample) and monitoring an analyte therein includes a disposable cartridge and a local controller module. The disposable cartridge includes a sampling module adapted to extract a bodily fluid sample and an analysis module adapted to measure an analyte (e.g., glucose) in the bodily fluid sample. The local controller module is in electronic communication with the disposable cartridge and is adapted to receive and store measurement data from the analysis module. An ISF extraction device includes a penetration member configured for penetrating and residing in a target site of a user's skin layer and, subsequently, extracting an ISF sample therefrom. The device also includes a pressure ring(s) adapted for applying pressure to the user's skin layer in the vicinity of the target site. The device is configured such that the pressure ring(s) is capable of applying pressure in an oscillating manner whereby an ISF glucose lag of the ISF sample extracted by the penetration member is mitigated. A method for extracting ISF includes providing an ISF fluid extraction device with a penetration member and a pressure ring(s). Next, a user's skin layer is contacted by the pressure ring(s) and penetrated by the penetration member. An ISF sample is then extracted from the user's skin layer while pressure is being applied in an oscillating manner by the pressure ring(s). The oscillating pressure mitigates an ISF glucose lag of the extracted ISF sample.
Abstract:
A cassette containing cartridges for sampling blood from a patient. The cassette includes a container for storing a plurality of cartridges and at least one cartridge in the container. The cartridge includes a cartridge case and a lancet. The lancet has a tip and is housed in the cartridge case. The lancet can be driven to extend the tip outside the cartridge case for lancing the skin of the patient to yield blood. The container has a compartment that contains at least one cartridge. A cartridge from the compartment can be loaded onto a glucometer that drives the lancet in the cartridge to lance the skin of a patient.
Abstract:
In some aspects, an analyte sensor is provided for detecting an analyte concentration level in a bio-fluid sample. The analyte sensor may include one or more conductors received in a hollow portion of a hollow member. The first conductor may be made, at least in part, of a semiconductor material and an active region may be provided in contact with at least the first conductor. The analyte sensor may, in one aspect, include a lancet and an integrated sensor. Manufacturing methods and apparatus and systems utilizing the analyte sensors are provided, as are numerous other aspects.

Abstract:
Systems, devices and methods for determining the concentration of physiological fluid analytes are provided. The subject systems have a plurality of biosensor devices present on a disposable cartridge. Each biosensor device includes a biosensor and a skin penetration means. In practicing the subject methods, a movement means of the device is used to move each biosensor device in a first direction that provides for penetration of the skin-piercing means into a skin layer followed by movement of the biosensor in a second direction that provides for removal of the skin-piercing means from the skin layer, where this movement profile provides for physiological fluid access and analyte concentration determination by the analyte sensor means. The subject systems, devices and methods for using the same find use in determining the concentration of a variety of different physiological fluid analytes, and are particularly suited for use in detection of physiological fluid glucose concentration.
