Application: Fixed bed bioreactor vessel and methods of using the same (Patent ID: US20230348834A1)
The patent filed by Corning Inc. describes a packed-bed bioreactor that includes a vessel with an interior cavity, a center column with a columnar sidewall separating inner and outer regions, a cell culture substrate surrounding the center column, at least one port for media supply and removal, and a fountain head element above the center column. The bioreactor may also include a mixer to circulate media through the inner and outer regions, creating a turbulence zone to mix fluids like caustic, cell culture media, oxygen, nitrogen, and nutrients.
Additionally, the fountain head element is designed to redirect media from the inner region towards the outer wall in a thin film, exposing it to oxygen before entering the outer region. The patent also mentions the presence of a capture zone below the cell culture substrate to collect spent media, with sensors to measure various parameters like pH, dissolved oxygen, temperature, and composition. A controller is included to adjust the bioreactor's properties based on sensor signals, and the cell culture substrate can be made of porous materials like molded polymer lattice, 3D-printed polymer lattice sheet, woven mesh sheet, or dissolvable foam scaffold. The design of the bioreactor aims to optimize the culture conditions for cells in a controlled and efficient manner.
