    Patent number: 4507810
    Abstract: An implantable breast prosthesis having a shell of bio-compatible material filled with a plurality of individual, irregularly shaped cells. The shell is at least partially filled with a liquid.

Cells are interconnected with the shell and with each other so as to avoid excessive movement.
