Abstract: The invention features devices for capturing and culturing cells (e.g., microorganisms, cells containing microorganisms, or cells from eukaryotic cell cultures) and methods of using these devices. One device is a cassette containing growth media that may be employed in an automated rapid enumeration system. The cassette has, for example, been enhanced with features for controlling surface flatness, optical imaging, controlled dehydration of semi solid nutrient media, controlled air and particle exchange, and automated handling. Another device of the invention is a filtration funnel that may used to concentrate cells in a sample onto a membrane.

Abstract: An analyte test device is constructed as an integrated, single-use, disposable cartridge which can be releasably installed into a compatible analyte test monitor. In use, the device can be used in conjunction with the monitor to lance the skin of a patient to create a blood sample and, in turn, calculate the concentration of a particular analyte in the expressed blood sample. In one embodiment, the device includes a base and a cover which are affixed together to create a test cartridge which has a substantially flat and low profile design. A lancet carrier is disposed between the base and the cover and includes a anchor fixedly mounted on the base and a lancet support member which is slidably mounted on the base, the anchor and the lancet support member being connected by a spring. A lancet is removably mounted on the lancet support member is disposed directly beneath an analyte test strip which secured to the underside of the cover.

Abstract: An article suitable for conducting one or more assays with an apparatus, e.g., a meter, for determining the presence or concentration of an analyte in a sample of biological fluid. The article contains a plurality of biosensors arranged in such a manner that each of the biosensors can be utilized before the article must be removed from the apparatus.

Abstract: An analyte test device is constructed as an integrated, single-use, disposable cartridge which can be releasably installed into a compatible analyte test monitor. In use, the device can be used in conjunction with the monitor to lance the skin of a patient to create a blood sample, express the blood sample from the wound site using vacuum forces and calculate the concentration of a particular analyte in the expressed blood sample. In one embodiment, the device includes a base which includes a top surface and a bottom surface. The base is also shaped to define an aperture which extends transversely through its top and bottom surfaces. An electrochemical test sensor is affixed to the base in such a manner so that a vacuum path is at least partially defined between the base and the test sensor, the vacuum path being in fluid communication with the aperture.
