Abstract
The invention relates to a method for the manufacture of a breast prosthesis, comprising: providing and superimposing inner and outer plastic foils; welding together the plastic foils to form the circumferential welding seam, thereby leaving a gap to form a filling channel connecting the inner space to an outside; filling the inner space with a fluid curable mass, which is a precursor of the filler material, by injecting the fluid curable mass into the inner space through the filling channel; and curing the fluid curable mass inside the inner space to form the filler material; wherein the filling channel is provided with a check valve to prevent fluid curable mass from entering the filling channel after injection. The invention additionally proposes a breast prosthesis made by such method.
Claims13
A method for the manufacture of a breast prosthesis,
- the breast prosthesis comprising:
- a shell, the shell comprising inner and outer plastic foils that are welded together along a common circumference to form a circumferential welding seam and define an inner space of the shell, the inner space being filled with a filler material;
- and
- the method comprising:
- providing and superimposing inner and outer plastic foils;
- welding together the plastic foils to form the circumferential welding seam, thereby leaving a gap to form a filling channel connecting the inner space to an outside;
- filling the inner space with a fluid curable mass, which is a precursor of the filler material, by injecting the fluid curable mass into the inner space through the filling channel;
- and
- curing the fluid curable mass inside the inner space to form the filler material;
- wherein the filling channel is provided with a check valve to prevent fluid curable mass from entering the filling channel after injection, and wherein the check valve is a flapper valve.

- and
- wherein a support tube is inserted into the filling channel prior to the injecting of the fluid curable mass and wherein the fluid curable mass is injected into the inner space through the support tube.
