The invention relates to an implantable device (1) for injecting and/or withdrawing fluid, comprising a housing (3) provided with a puncture area (4) configured in such a way that it can be pierced by a needle (5) in order to inject and/or withdraw fluid in a chamber (3A) fitted inside the housing, characterized in that said puncture area (4) comprises at least one and one second flexible membrane (6,7) which are superposed and freely mounted at least locally in relation to each other in order to enable, at least locally, displacement of one along the other such that the opening made by the needle (5) is divided up into sections of a first and second sub-opening (6A,7A) which do not coincide substantially in order to make the puncture area (4) substantially tight. Implantable medical sites.
