A recoverable article comprising an inner resilient tubular member (4) that is held in a laterally expanded configuration by engagement with outer holdout means (6), wherein the outer surface of the inner member (4) is provided with a plurality of channels extending therealong and the holdout means occupies the channels so as to provide said holdout engagement, wherein the holdout means (6) is arranged to be removed intact without any substantial change in the molecular structural properties of the holdout means, thereby to allow recovery of the inner tubular member (4) towards its unexpanded configuration.
