Patent number: 8262996Abstract: A sensor utilizing a non-leachable or diffusible redox mediator is described. The sensor includes a sample chamber to hold a sample in electrolytic contact with a working electrode, and in at least some instances, the sensor also contains a non-leachable or a diffusible second electron transfer agent. The sensor and/or the methods used produce a sensor signal in response to the analyte that can be distinguished from a background signal caused by the mediator. The invention can be used to determine the concentration of a biomolecule, such as glucose or lactate, in a biological fluid, such as blood or serum, using techniques such as coulometry, amperometry; and potentiometry. An enzyme capable of catalyzing the electrooxidation or electroreduction of the biomolecule is typically provided as a second electron transfer agent.Type: GrantFiled: September 29, 2009Date of Patent: September 11, 2012Assignee: Abbott Diabetes Care Inc.Inventors: Benjamin J. Feldman, Adam Heller, Ephraim Heller, Fei Mao, Joseph A. Vivolo, Jeffery V. Funderburk, Fredric C. Colman, Rajesh Krishnan

Patent number: 8260392Abstract: An analyte monitor includes a sensor, a sensor control unit, and a display unit. The sensor has, for example, a substrate, a recessed channel formed in the substrate, and conductive material disposed in the recessed channel to form a working electrode. The sensor control unit typically has a housing adapted for placement on skin and is adapted to receive a portion of an electrochemical sensor. The sensor control unit also includes two or more conductive contacts disposed on the housing and configured for coupling to two or more contact pads on the sensor. A transmitter is disposed in the housing and coupled to the plurality of conductive contacts for transmitting data obtained using the sensor. The display unit has a receiver for receiving data transmitted by the transmitter of the sensor control unit and a display coupled to the receiver for displaying an indication of a level of an analyte.Type: GrantFiled: June 9, 2008Date of Patent: September 4, 2012Assignee: Abbott Diabetes Care Inc.Inventors: James Say, Michael F. Tomasco, Adam Heller, Yoram Gal, Behrad Aria, Ephraim Heller, Phillip John Plante, Mark S. Vreeke, Keith A. Friedman, Fredric C. Colman
