Patent number: 11925934Abstract: Microfluidic devices for cell sorting or cell fractionation are disclosed. A microfluidic device can comprise one or more inlets, a first wall and a second wall, and two or more outlets. The first and second walls can be substantially planar to each other and the first wall having can have a plurality of ridges protruding from the first wall and defining a compression gap between the ridge and a surface of the second wall. The microfluidic device can also be a cell sorting device for sorting a plurality of cells based on one or more biophysical cellular properties including size, elasticity, viscosity, and/or viscoelasticity wherein the cells are subjected to one or more compressions due to the compression gap. Also disclosed are methods for cell sorting based on a variety of biophysical cellular properties.Type: GrantFiled: July 1, 2020Date of Patent: March 12, 2024Assignee: Georgia Tech Research CorporationInventors: Todd Sulchek, Alexander Alexeev, Gonghao Wang

Patent number: 11400321Abstract: A system configured to create a self-contained negative pressure environment (SCONE) to remove airborne particulates emitted from a patient. The system prevents exposure to pathogenic biological airborne particulates during triage, transportation, and treatment, including aerosol generating procedures (AGPs) and end of life care. This system is directed to a collapsible device having a flexible cover covering two support members, with openings in the flexible cover such that medical professionals can reach in and operate within. The present invention is further adaptable to patients and operating environments of various sizes.Type: GrantFiled: March 31, 2021Date of Patent: August 2, 2022Assignee: SCONE MEDICAL SOLUTIONS INC.Inventors: Michael Adams, Kristen Adams, Joseph V. Ranalletta, Gonghao Wang

Patent number: 10709370Abstract: A blood separation device adapted to receive a blood sample having a whole blood portion and a plasma portion is disclosed. The blood separation device includes a housing defining a first chamber, a second chamber, and a separation member disposed therebetween. The blood separation device also includes an actuator, wherein actuation of the actuator draws the blood sample into the first chamber and the separation member is adapted to allow the plasma portion to pass through the separation member to the second chamber. The blood separation device matches the plasma chamber volume, the blood chamber volume, and the applied single pressure source so that the correct trans-membrane pressure and shear rate is obtained.Type: GrantFiled: June 9, 2017Date of Patent: July 14, 2020Assignee: Becton, Dickinson and CompanyInventors: Qihua Xu, Gonghao Wang

Patent number: 8356714Abstract: An apparatus for separating particles includes a first planar wall and a spaced apart second planar wall parallel to the first planar wall. The first planar wall and the second planar wall define a passage therebetween, which is disposed along a fluid flow axis. A first plurality of spaced apart elongated ridges extends into the passage from the first planar wall. The first plurality of spaced apart elongated ridges is disposed along a diagonal direction relative to the fluid flow axis. When a fluid is moved through the passage in a direction corresponding to the fluid flow axis, particles of a first type will tend to move in a first direction that is diagonally away from the fluid flow axis and particles of a second type, different from the first type, will tend to move in a second direction that is different from the first direction.Type: GrantFiled: June 2, 2010Date of Patent: January 22, 2013Assignee: Georgia Tech Research CorporationInventors: Todd A.
