Abstract:
1. An implantable device for injecting fluid into or for tapping fluid from either an organ or vessel of the body of a human or animal patient, or an inflatable and/or deflatable compartment of a surgical implant, comprising: a housing having a puncture zone suitable for being transpierced by a hollow needle for injecting fluid into and/or tapping fluid from a chamber inside the housing, wherein the puncture zone is made up of at least a first and a second superposed flexible membranes mounted to be free, at least locally, relative to each other, to allow the first and the second superposed flexible membranes, at least locally, to move along each other, so that, once the needle has been removed, the orifice formed by the needle is sliced into a first sub-orifice formed in the first membrane and a second sub-orifice formed in the second membrane and substantially not coinciding so as to impart a substantially leaktight property to the puncture zone, wherein the housing further comprises a perforated skeleton, the skeleton having a inner side and an outer side, the first membrane being provided in the form of a first extensible sheath and the second membrane being provided in the form of a second extensible sheath, the first sheath covering the skeleton to form a sheathed skeleton, and the second sheath is force-fitted over the first sheath and, wherein the first and second membranes are each on the same side of the skeleton.
