Application No. 09/207,631
BACKGROUND
Appellant's invention relates to a method of manufacturing a
molded breast prosthesis. An understanding of the invention can
be derived from a reading of claim 15, the sole independent claim
on appeal, which is reproduced below.
15. A method of manufacturing a moulded, foil-
wrapped breast prosthesis comprising joining two foil
sheets of a formable plastic material to provide a
prosthesis bag, said foil sheets forming a front side
and a rear side, respectively, of said bag and said
bag having a filling opening;
filling said bag with a quantity of a curable
compound and thereafter sealing the filling opening of
the bag;
placing the filled bag into a mould cavity of a
mould, said mould cavity having an opening and a
bottom wall with a surface corresponding to a desired
shape of said front side of the prosthesis, said front
side being placed in contact with said bottom wall
surface;
applying vacuum to said bottom wall of the mould
cavity to bring the bag into close contact therewith;
whereafter the compound is cured and the moulded
prothesis is removed from the mould, characterized in
that the curing is performed without closing the mould
cavity at said opening and the vacuum is maintained
until at least the compound closest to said front side
of the bag placed in close contact with said bottom
wall surface in cured.
