摘要：
An inflatable sleeve or packer includes a mandrel that extends along a longitudinal axis and a sealed inflatable jacket which is connected to the mandrel and selectively adopts a rest configuration or a maximum inflation configuration. The sleeve also includes a restraining sheath which covers the inflatable jacket and is at least partially formed by essentially inextensible fibers including peripheral fibers which each extend around the longitudinal axis, the peripheral fibers adopting a pleated configuration for the rest configuration of the jacket and a stretched configuration for the maximum inflation configuration thereof.
