  • Publication number: 20140243879
    Abstract: An embolic protection device includes a first filter configured to be disposed in a first vessel and a second filter configured to be disposed in a second vessel. A first tether extends from a proximal end of the first filter and a first magnet is coupled to the first tether. A second tether extends from a proximal end of the second filter and a second magnet is coupled to the second tether. The device is configured such that when the first filter is disposed in the first vessel and the second filter is disposed in the second vessel, the first magnet and the second magnet are magnetically coupled to each other to couple the first tether to the second tether.

  • Publication number: 20080033320
    Abstract: An interstitial fluid (ISF) extraction device includes a penetration member configured for penetrating a target site of a user's skin layer and, subsequently, residing in the user's skin layer and extracting an ISF sample therefrom and at least three concentrically-arranged pressure rings, each adapted for applying pressure to the user's skin layer in the vicinity of the target site while the penetration member is residing in the user's skin layer. In addition, the ISF extraction device is configured such that (i) the pressure rings apply pressure in an oscillating manner with asymmetric deployment and retraction cycles and (ii) only one of the at least three concentrically-arranged pressure rings is deployed at a time, thereby mitigating an ISF glucose lag of the ISF sample extracted by the penetration member.

  • Publication number: 20060036187
    Abstract: Systems and methods are provided for extracting a bodily fluid sample (e.g., an interstitial fluid sample) and monitoring an analyte therein. Certain of the systems include a a penetration member configured for penetrating and residing in a target site of a user's skin layer and, subsequently, extracting a fluid sample therefrom. The system also includes a pressure ring(s) adapted for applying pressure to the user's skin layer in the vicinity of the target site. The system is configured such that the pressure ring(s) is capable of applying pressure in an oscillating manner. Certain methods include penetrating the skin and applying pressure to the skin in an oscillating manner.

  • Publication number: 20050180881
    Abstract: A body fluid is collected for testing for an analyte contained within the body fluid. The fluid is collected in an apparatus including a reservoir for receiving and collecting a flow of body fluid from a discharge end of a conduit. A capillary test space is in fluid flow communication with the reservoir. The capillary test space is positioned to be in contact with the fluid in the reservoir after the fluid has accumulated to a predetermined transfer volume of fluid. The capillary test space is sized to wick the fluid from the reservoir when the fluid contacts the capillary test space.

  • Publication number: 20050002018
    Abstract: An analyte (e.g., glucose) is tested in a sample (e.g., blood or blood-free interstitial fluid) having both the analyte and other constituents (e.g., protein). The analyte has an absorption peak over a narrow bandwidth at a characteristic wavelength. The other constituents have an absorption over a broad bandwidth. The broad bandwidth includes and is broader than the narrow bandwidth. Radiant energy (e.g., IR radiation) is directed at the sample. The energy has a source bandwidth including the broad bandwidth. The sample absorbs a portion of the energy. A remainder of the energy is available for analysis. The remainder is analyzed by filtering the remainder into an analyte portion and a reference portion. The analyte portion contains substantially only the narrow bandwidth. The reference portion contains substantially only the broad bandwidth. The analyte portion and the reference portion are measured and compared to calculate an amount of the analyte in the sample.

  • Publication number: 20040249253
    Abstract: A system for extracting a bodily fluid sample (e.g., an interstitial fluid [ISF] 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.
