Patent number: 9987576Abstract: A mechanical input to a fluidic filter network can be actuated. The fluidic filter network can include respective branches fluidically coupling the mechanical input to respective deformable mechanical outputs. A mechanical displacement can be selectively coupled a selected deformable mechanical output of the fluidic filter network to a deformable mechanical input of a microfluidic device. A fluid flow in a portion of the microfluidic device can be controlled using the displacement, the selected deformable mechanical output can be selected at least in part by actuating the mechanical input to produce a displacement having energy in a specified range of frequencies, and the fluidic filter network is generally fluidically isolated from the microfluidic device.Type: GrantFiled: December 10, 2013Date of Patent: June 5, 2018Assignees: University of Virginia Patent Foundation, The Regents of the University of CaliforniaInventors: James P. Landers, Matthew R. Begley

Publication number: 20170224968Abstract: Systems and methods for use in monitoring treatment of pressure-related conditions, such as hydrocephalus, include an implantable vessel, and a meter including one or more microfluidic channels connected to the vessel. The microfluidic channels may be configured to detect at least one of pressure and fluid flow rate through the vessel and to be read out remotely by a wirelessly coupled external device. The meter may include a passive resonant (LC) circuit. A dynamic flap may be included in the microfluidic channel that may act as part of the LC circuit. An external device may also be configured to inductively couple remotely to the LC circuit, with-out physical connections to the implantable vessel or pressure meter, and to display a pressure acting on the pressure meter and/or a fluid flow through the meter.Type: ApplicationFiled: April 26, 2017Publication date: August 10, 2017Inventors: Marcel Utz, George T. Gillies, William Broaddus, John A. Jane, Matthew R. Begley
