Abstract
Abstract A breast prosthesis comprises a semi-rigid flat bottom portion with a first inner covering portion extending over the bottom and connected adjacent its periphery to the bottom and being inflatable outwardly therefrom and a second cover portion extending over the first cover portion and being secured at its periphery either to the first cover portion or the bottom and being filled with a liquid. The space between the inner covering and the bottom comprises an inflatable chamber which is inflated through an opening defined at the breast-like structure and it includes a sealing member having a filling opening therein which is closed interiorly by superposed flap members which may be spread apart to permit insertion of a gas filling tube.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
147 words
A breast prosthesis comprising an inflatable bag diVided into superposed chambers, one of said chambers having liquid therein and the other being inflatable, said bag including a flat bottom adapted to be oriented toward the body, a first inner expansible covering extending over the bottom and defining the inflatable chamber between said first covering and said bottom, said inflation chamber being inflatable to expand said first inner covering outwardly from said bottom and a second outer expansible covering overlying the whole of said first covering and secured around its periphery over said first covering and to said bottom, the space between said first and second expansible covering defining a liquid chamber having liquid therein, said first inner covering portion being expandable upon inflation into the liquid of said liquid chamber to at least partly modify the shape of said liquid chamber and said second outer expansible covering.
Claim 2
Dependent Claim
