Publication number: 20240115781Abstract: Systems and apparatuses for blood oxygenation are disclosed. A system includes a first layer defining a plurality of banks of first channels each extending in a first direction. The plurality of banks of first channels are configured to receive blood via a trunk channel. The system includes a second layer defining a bank of second channels extending in a second direction. The bank of second channels are configured to receive oxygen. The first direction is different from the second direction. The system includes a membrane disposed between the first layer and the second layer and configured to cause the oxygen to permeate from the second layer to the first layer to oxygenate the blood.Type: ApplicationFiled: October 3, 2023Publication date: April 11, 2024Applicant: The Charles Stark Draper Laboratory, Inc.Inventors: Brett Isenberg, Else Vedula, David Sutherland, Diana Lewis, Jose Santos, WeiXuan Lai, Ernie Kim, Beau Landis, Jeffrey Borenstein, Bryan Teece, Samuel Blumenstiel, Joseph Urban
