Abstract: Medical devices configured for in vivo assays of one or more analytes can sometimes be problematic if left inserted in a tissue, such as skin, for an extended time. Certain medical device surface profiles may aid in alleviating this issue. Accordingly, medical devices may comprise a base surface having a tissue-facing surface profile defined thereon, and a sensor extending through the base surface and at least a portion of the tissue-facing surface profile. The tissue-facing surface profile deviates from the base surface, and the tissue-facing surface profile is also configured to undergo a change in shape, hardness, or a combination thereof after contacting a tissue for a length of time. A dynamic material may be present in at least a portion of the tissue-facing surface profile.

Abstract: A transcutaneous sensor configured to measure one or more physiological conditions of a patient. The transcutaneous sensor includes a substrate and first and second working electrodes on the substrate. The first working electrode includes a first active sensing area and the second working electrode includes a second active sensing area. The first active sensing area of the first working electrode is longitudinally offset along the substrate from the second active sensing area of the second working electrode.

Abstract: Generally, embodiments of the invention relate to self-powered analyte determining devices (e.g., electrochemical analyte monitoring systems) that include a working electrode, a counter electrode, and an optional resistance value, where the working electrode includes analyte sensing components and the self-powered analyte determining device spontaneously passes a current directly proportional to analyte concentration in the absence of an external power source. Also provided are systems and methods of using the, for example electrochemical, analyte sensors in analyte monitoring.
