  • Microfluidic device for generating neural cells to simulate post-stroke conditions
    Patent number: 9632076
    Abstract: This application provides devices for modeling ischemic stroke conditions. The devices can be used to culture neurons and to subject a first population of the neurons to low-oxygen conditions and a second population of neurons to normoxic conditions. The neurons are cultured on a porous barrier, and on the other side of the barrier run one or more fluid-filled channels. By flowing fluid with different oxygen levels through the channels, one can deliver desired oxygen concentrations to the cells nearest those channels.
    Type: Grant
    Filed: November 12, 2014
    Date of Patent: April 25, 2017
    Assignees: The Charles Stark Draper Laboratory, Inc., The University of South Florida
    Inventors: Anilkumar Harapanahalli Achyuta, Javier Cuevas, Shivshankar Sundaram, Chris Katnik
