Patent number: 11918348Abstract: 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.Type: GrantFiled: November 30, 2018Date of Patent: March 5, 2024Assignee: Abbott Diabetes Care Inc.Inventors: Jonathan McCanless, Hyun Brian Cho, Benjamin Feldman, Frank David Fujimoto

Publication number: 20220273200Abstract: 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.Type: ApplicationFiled: March 28, 2022Publication date: September 1, 2022Applicant: ABBOTT DIABETES CARE INC.Inventors: Steven T.

Patent number: 7958887Abstract: The present invention describes the configuration of a porous sheet for improving the efficiency for generating an aerosol from a liquid formulation. This aerosolized liquid formulation can be used for intrapulmonary delivery of pharmaceutically active drugs and diagnostic agents when said invention is used in conjunction with the appropriate device. The individual pores in each array (defined as the rows and columns of pores for example in a rectangular array) are generated such that there is a discrete or continuous variation in the pore size within the plurality of pores on the sheet. The drug is subsequently aerosolized by forcing the liquid formulation through the pores on the sheet. The resulting aerosol will contain a controlled range of particle sizes defined by the properties of the porous sheet and the liquid formulation.Type: GrantFiled: March 8, 2007Date of Patent: June 14, 2011Assignee: Aradigm CorporationInventors: Giles Kelliher, David Fujimoto, Justin Drish
