    摘要: Methods and apparatus are provided for point-of-care nucleic acid amplification and detection. One embodiment of the invention comprises a fully integrated, sample-to-answer molecular diagnostic instrument that optionally may be used in a multiplexed fashion to detect multiple target nucleic acid sequences of interest and that optionally may be configured for disposal after one-time use. Optionally, sample preparation is fully or partially achieved via heat treatment and/or using a filter paper, such as a chemically treated filter paper, e.g., an FTA card. The instrument preferable utilizes an isothermal nucleic acid amplification technique, such as loop-mediated isothermal amplification (LAMP), to reduce the instrumentation requirements associated with nucleic acid amplification. Detection of target amplification may be achieved, for example, via detection of a color shift or fluorescence in a dye added to the amplification reaction.

    摘要: The apparatus is provided for sealing a vascular puncture tract by forming the autologous plug within the puncture tract, and extruding that plug into the puncture tract. The apparatus of the present invention forms an autologous blood plug by drawing blood into the apparatus from a vessel, mixing a blood congealing agent with the drawn blood, and ejecting a plug formed from the clotted blood within the puncture tract. Also provided are various closure elements to isolate the drawn blood from the vessel during mixture with the blood congealing agent, and to facilitate placement of the apparatus relative to the vessel.

    摘要: The present invention provides methods and apparatus for endovascularly replacing a patient's heart valve. The apparatus includes a replacement valve and an expandable anchor configured for endovascular delivery to a vicinity of the patient's heart valve. In some embodiments, the replacement valve is adapted to wrap about the anchor, for example, by everting during endovascular deployment. In some embodiments, the replacement valve is not connected to expandable portions of the anchor. In some embodiments, the anchor is configured for active foreshortening during endovascular deployment. In some embodiments, the anchor includes expandable lip and skirt regions for engaging the patient's heart valve during deployment. In some embodiments, the anchor comprises a braid fabricated from a single strand of wire. In some embodiments, the apparatus includes a lock configured to maintain anchor expansion. The invention also includes methods for endovascularly replacing a patient's heart valve. In some embodiments, the method includes the steps of endovascularly delivering a replacement valve and an expandable anchor to a vicinity of the heart valve, wrapping at least a portion of the replacement valve about the anchor, and expanding the anchor to a deployed configuration.
