Abstract
Miniature stirred tank bioreactor and system; the bioreactor configured for single use culturing, providing unobstructed culturing volume with sensors, probes and ports using minimally invasive placement in-wall or across the wall methods; the bioreactor further capable of containing scaffolds and features for culturing cells and tissue, including structures providing surfaces for cell growth, and screens for retaining microparticles during media exchange
Claims15
1-45. (canceled)
A disposable stir tank bioreactor vessel such that inside said vessel there is a rotatable shaft, said shaft comprising a plurality (two or more) of concentric tubes such that there is a space between each tube and its closest neighboring tube, such that said space is accessible by bioreactor fluid from below (preferably the top of the space is not blocked thereby permitting continuous upward low of fluid within the space).
(canceled)
A disposable stir tank bioreactor vessel comprising internal vertical columns, said columns either solid with an external surface or tubular with both internal and external surfaces.
(canceled)
A bioreactor vessel, such that inside said vessel there is a rotatable shaft, said vessel further comprising one or more platforms (for example, discs) centered around and connected to said shaft, said vessel further comprising a three-dimensional structure attached to said platform, said structure coated at least in part with a material permitting cell attachment and growth (preferably adapted for animal or human cells).
(canceled)
A disposable stir tank bioreactor vessel, such that inside said vessel there is a rotatable shaft, said vessel further comprising a screen enclosing a space (or volume of fluid) surrounding the shall so as to prevent microcarriers that are in that space or volume from escaping that space or volume.
