Abstract: A cell cultivation apparatus for cultivating microorganisms and growing cells at high density is provided. The apparatus includes a membrane comprising multiple surface features on a first side of the membrane for cell placement. The surface features comprising one or more compartments within which a cell can be located. The membrane includes a material that is at least partially permeable to gas. A second side of the membrane defines a gas region. The second side of the membrane is separated from the first side of the membrane by the membrane. The apparatus further includes a media region for receiving media. The compartments are configured to at least partially reduce media flow shear forces on one or more cells in the compartments. The surface features may be ridges, protrusions, fins, wells, and/or posts.

Abstract: Methods of manufacture, devices, and systems are described for a nasal swab. The swab includes an elongated body having a distal end. The swab includes a collection layer proximate to the distal end of the elongated body. The collection layer has a first geometric layout and configured to collect samples in the nasal passageway. The swab includes a collection tip at the distal end of the elongated body, the collection tip having a second geometric layout and configured to collect samples in the nasal passageway. The first geometric layout is different from the second geometric layout.

Abstract: An oxygen transporter device configured to transport O2 from an ambient air location into or toward a subcutaneous site. The device includes an absorption component, a cannula, and a discharge component configured to be implanted in a subcutaneous location while the absorption component is not subcutaneous. The cannula can extend through or across the skin of a patient. The discharge component can includes one or more multi-layered, flexible mesh sheets, which are coupled to cells.

Abstract: Oxygen-charged (or oxygen-rich) implantable medical devices for and methods of local delivery of oxygen via outgassing is disclosed. The presently disclosed oxygen-charged implantable medical devices are, for example, polymeric implants that are functionalized to locally deliver oxygen from the implant surface for prolonged periods of time, thus increasing rates of healing and reducing rates of infection as compared with conventional medical implant devices.
