A prosthesis for repairing a tissue or muscle wall defect includes a plurality of petals connected to one another at a common center. The petals are arranged in circular fashion and cooperate to form a substantially flat disc. The petals are also arranged in an overlapping manner such that each of the petals is movable relative to an adjacent pair of the petals. The petals are sized and shaped such that at least some of the petals come in direct contact with a surrounding structure of a tissue defect when the prosthesis is inserted therein.
