Patent number: 8437829Abstract: Novel membranes comprising various polymers containing heterocyclic nitrogen groups are described. These membranes are usefully employed in electrochemical sensors, such as amperometric biosensors. More particularly, these membranes effectively regulate a flux of analyte to a measurement electrode in an electrochemical sensor, thereby improving the functioning of the electrochemical sensor over a significant range of analyte concentrations. Electrochemical sensors equipped with such membranes are also described.Type: GrantFiled: August 20, 2009Date of Patent: May 7, 2013Assignee: Abbott Diabetes Care Inc.Inventors: Fei Mao, Hyun Cho

Patent number: 8435179Abstract: Systems and methods for minimizing or eliminating transient non-glucose related signal noise due to non-glucose rate limiting phenomenon such as ischemia, pH changes, temperatures changes, and the like. The system monitors a data stream from a glucose sensor and detects signal artifacts that have higher amplitude than electronic or diffusion-related system noise. The system replaces some or the entire data stream continually or intermittently including signal estimation methods that particularly address transient signal artifacts. The system is also capable of detecting the severity of the signal artifacts and selectively applying one or more signal estimation algorithm factors responsive to the severity of the signal artifacts, which includes selectively applying distinct sets of parameters to a signal estimation algorithm or selectively applying distinct signal estimation algorithms.Type: GrantFiled: January 27, 2011Date of Patent: May 7, 2013Assignee: DexCom, Inc.Inventors: Paul V. Goode, Jr., James H. Brauker, Apurv U. Kamath, James Patrick Thrower, Victoria Carr-Brendel
