  • Patent number: 11918348
    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.

  • Publication number: 20220386911
    Abstract: An analyte sensor and methods and systems related thereto, where at least one or more of a lower portion of a sensor tail substrate, at least one electrode, a sensing element, a membrane, and an optional non-electrochemical functional layer comprise an antimicrobial quality. Asymmetric, double-sided adhesive binders suitable for adhering the analyte sensor to a skin surface comprising a non-woven scrim, a first pressure-sensitive adhesive layer, a second pressure-sensitive adhesive layer. Overbandages comprising a vapor-permeable backing, an aperture to circumferentially surround a sensor housing, a contact adhesive layer, first and second peelable release liners, and a third peelable release liner disposed upon an anchoring adhesive strip of the contact adhesive layer.

  • Publication number: 20220273200
    Abstract: On-body analyte sensors may be designed for extended wear to provide ongoing measurement of physiological analyte levels. However, on-body analyte sensors may be susceptible to damage or dislodgment during wear due to routine interactions that occur with one's surroundings. Guard rings may be adapted to protect on-body analyte sensors from such interactions. Guard rings may comprise an annular body comprising an inner perimeter face, an outer perimeter face, a top edge, and a bottom face adapted for contacting a tissue surface. The inner perimeter face is shaped to circumferentially surround a sensor housing of an on-body analyte sensor. At least a portion of the outer perimeter face defines a chamfered surface extending between the top face and the bottom face. Adhesive pads or strips may further be engaged with the guard rings and aid in securing the guard rings to a surface, such as skin.

  • Patent number: 8919607
    Abstract: An analyte test strip vial having a restrictor to dispense analyte test strips in a controlled manner. In general, the restrictor includes one or more openings (e.g., central and/or arc-shaped openings) that are appropriately sized to facilitate the dispensing of a manageable number of analyte test strips from the vial container. The restrictor may also include one or more surface features (e.g., tabs, cavities, and/or tapered surfaces) to facilitate in the removal of analyte test strips, and the matting and/or removal of the restrictor from the vial container.
