The essential step of the novel coating process for covering plastic vascular prostheses with living cells consists in stepwise rotations of the prosthesis filled with a cell suspension by set angles and in settling pauses between the rotations, the duration of which, beginning with 2 sec, is increased in small proportions from 1 to 2 sec up to pause lengths of 2 to 3 min. �<??>A uniform covering of the inner wall of the prosthesis with a layer of living cells without any streaks or gaps is obtained with the novel process.
