1. A surgically implantable rupture-resistant breast prosthesis comprising:

  • a flexible, creasable shell of silicone polymer adapted to contain a saline inflating liquid and having a wall with inner and outer surfaces; and

    an abrasion resistant hydrogel layer having substantially greater lubricity than the shell bonded to one of such wall surfaces to substantially reduce self-abrasion damage to the shell wall during sliding contact between opposing areas of this one surface when a saline inflating liquid is confined within the shell and the shell wall has a crease after surgical implantation.
