A method for repairing an intervertebral disc, said disc comprising an annulus that substantially surrounds a nuclear space and is located between first and second adjacent vertebrae, said annulus having a wall, said method comprising: inserting an inflatable implant in a collapsed configuration through a passageway formed across the annulus wall and into the nuclear space; wherein said inflatable implant comprises, inflating said implant within the nuclear space from the collapsed configuration to an expanded configuration that a first portion of the membrane is located adjacent the first vertebra, a second portion of the membrane located opposite the first portion is positioned adjacent the second vertebra; wherein said internal self-sealing fill valve comprises internal opposing walls that are disposed relative to the membrane so as to collapse as a result of a compressive load between the first and second vertebrae, and thus between the first and second membrane portions, and thereby disposed on said internal chamber.
