Abstract
An artificial capillary cell culture device having two separate perfusion circuits, and with the ultrafiltration fibers of the two circuits being woven into a single bundle, is disclosed. The present device provides a matrix for high density growth of cultured cells in a continuous perfusion system. The device is particularly well adapted for the use of pressure differences between perfusion circuits, such as in the simulation of lymphatic drainage.
