Breast implant with low coefficient of friction between internal shells in an aqueous fluid environment

摘要

A fluid-filled surgically-implantable prosthetic device encloses one or more non-enclosing fitted shells arranged adjacent to and in a graduated relation to each other. The invention relates specifically to implantable breast prostheses with a low coefficient of friction between two or more interacting elastomeric shells in an aqueous fluid environment, without the addition of a lubricating agent to the fluid.
