Process for coating tubular prostheses, especially vascular prostheses.

摘要

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.
