Abstract

Recoverable articles including an inner resilient tubular member that is held in a laterally expanded configuration by engagement with an outer holdout member are provided. The outer surface of the inner member is provided with a plurality of channels extending therealong. The holdout member occupies the channels so as to provide the holdout engagement. The holdout engagement is arranged to be weakened mechanically without any substantial change in the molecular structural properties of the holdout member, thereby to allow recovery of the inner tubular member towards its unexpanded configuration.
