  • Microfabricated artificial lung assist device, and methods of use and manufacture thereof
    Patent number: 9457138
    Abstract: The invention provides systems and methods for exchanging gas in an oxygenator device, and methods for preparing and using such oxygenator devices. The systems and methods can be used to transfer oxygen to blood to assist lung function in a patient.
    Type: Grant
    Filed: February 11, 2014
    Date of Patent: October 4, 2016
    Assignee: THE CHARLES STARK DRAPER LABORATORY, INC.
    Inventors: Jeffrey T. Borenstein, Joseph L. Charest, James Ching-Ming Hsiao, Tatiana Kniazeva
  • Methods for reducing the blood priming volume and membrane surface area in microfluidic lung assist devices
    Patent number: 9180239
    Abstract: A device and method for oxygenating blood is disclosed herein. The device includes a plurality of passive mixing elements that causes a fluid to mix as it flows through the device. The passive mixing elements continually expose new red blood cells to the portion of the flow channel where oxygenation can occur. Accordingly, in some implementations, the device and method uses less blood to prime the device and allows for the oxygenation of blood with a substantial shorter flow channel when compared to conventional oxygenation methods and devices.
