| 20080264506 | System and method for using electrowetting on dielectric (EWOD) for controlling fluid in a microfluidic circuit - A system for controlling fluid flow in a microfluidic circuit includes at least one microfluidic channel having a first fluid, a switch element coupled to the microfluidic channel, the switch element comprising at least one inlet, at least one outlet and a second fluid, the second fluid being immiscible with respect to the first fluid. The system also includes an actuator configured to alter the position of the second fluid, such that when in a first position, the second fluid allows the first fluid to flow from the at least one inlet to the at least one outlet, and such that when in a second position, the second fluid prevents the first fluid from flowing from the at least one inlet to the at least one outlet. | 10-30-2008 |
| 20090082552 | Microfluidic protein assay - A microfluidic device for separating a fluid sample into components is disclosed. The microfluidic device is used for assaying proteins for the purpose of identification of protein species. The microfluidic device employs integrated features such as a sample well for holding a protein sample, a thermal control device for heating the protein sample in the sample well, and a protein separation region in fluid communication with the sample well. Also disclosed is a method for assaying a protein sample. | 03-26-2009 |
| 20090087884 | Microfluidic nucleic acid amplification and separation - Microfluidic devices designed for assaying biochemical molecules are disclosed. The microfluidic devices are capable of assaying nucleic acids for identification of nucleic acid species. The microfluidic devices are adapted to carry out an amplification of the nucleic acid and subsequent separation of amplified nucleic acid species. Also disclosed is a method for amplifying and separating a nucleic acid sample on a microfluidic device. | 04-02-2009 |
| 20090087924 | MICROFLUIDIC REVERSE AFFINITY-BLOT DEVICE - The microfluidic reverse affinity-blot device of the present disclosure combines affinity binding for isolation and/or enrichment of protein(s) from a sample, followed by separation/identification thereof. In general terms, a microfluidic reverse affinity-blot device is a closed system of interconnected components that is comprised of defined points of entry and exit, wherein the interconnected components include a capture region upstream from a protein separation region and subsequent detection region. Methods of use are also described. | 04-02-2009 |
| 20090206293 | Flow Controller with Channel Having Deformable Wall - An apparatus and method for controlling the flow of fluid though a channel. A first substrate defines features comprising a first channel. At least a portion of the first channel is bounded a deformable material having a first contour in which the first channel has a first cross-sectional area and a second contour in which the first channel has a second cross-sectional area. | 08-20-2009 |
| 20110106101 | Steerable Stylet - A stylet for inserting an electrode array into a cochlea includes a first sensor insertable within a lumen of the electrode array and sensitive to force applied by a lumen wall to the first sensor and a first actuator adapted to move the electrode array in response to the force sensed by the first sensor. | 05-05-2011 |
| 20110139484 | Hermetic Electrical Feedthrough - A method for fabricating a hermetic electrical feedthrough includes engraving a circuitous groove into a surface of an electrically conductive monolithic slab so that the interior of the circuitous groove forms a pin. A dielectric material is formed in the circuitous groove. The pin is then electrically isolated from the surrounding material and provides electrical access through the hermetic feedthrough. | 06-16-2011 |
