Abstract
An implant configured to be placed in a living body to be expansively deformed and contractively deformed comprises a first layer that forms a filling unit that is configured to be filled with a filling material to maintain an expanded state of the implant, the first layer comprising a porous membrane; a second layer that covers the first layer, the second layer comprising at least one of (i) a fluid-impermeable membrane, and (ii) a gas-permeable porous membrane that is impermeable by liquids or gels; and an introduction port that communicates with the filling unit and is configured to introduce the filling material into the filling unit. An introduction region is formed between the first layer and the second layer, the introduction region being configured to receive a fluid permeating the first layer when the filling material is introduced into the filling unit.
