Patent number: 8652831Abstract: A disposable biosensor test strip is provided that includes a plurality of penetrating members. Each penetrating member is associated with a capillary chamber that has a depth suitable for capillary flow of blood and holds a volume of less than about 1.0 .?l of the blood sample. A working electrode and a counter or reference electrode are disposed within the capillary chamber. A reagent is proximal to or in contact with at least the working electrode. The reagent includes an enzyme and a mediator. The reagent reacts with glucose to produce an electroactive reaction product. A blood sample, containing glucose, is applied into the capillary chamber. The capillary chamber directs capillary flow of the blood sample into contact with the reagent to cause the blood sample to at least partially solubilize or hydrate the reagent. The blood sample is detected in the capillary chamber. The electroactive reaction product is electro-oxidized or electro-reduced at the working electrode.Type: GrantFiled: March 26, 2008Date of Patent: February 18, 2014Assignee: Sanofi-Aventis Deutschland GmbHInventor: Dirk Boecker

Patent number: 8650018Abstract: A system and method for predicting the onset of glaucoma uses a Finite Element Model (FEM) to obtain a response profile of the Optical Nerve Head (ONH) inside an eye. To do this, the FEM is programmed with data from first and second images of the ONH that are respectively taken at the beginning and the end of an imposed pressure differential (e.g. over a range of about 8kPa). The FEM is then subjected to a sequence of pressure increments and the resultant profile is compared with empirical data to predict an onset of glaucoma.Type: GrantFiled: February 10, 2012Date of Patent: February 11, 2014Assignee: Heidelberg Engineering GmbHInventor: Josef F.
