Title: Process for the manufacture of light breast prostheses
Inventor: WILD HELMUT
IPC: A61F2/12
Filed: 1995-04-12
Abstract: ABSTRACT OF THE DISCLOSURE      For the manufacture of breast prostheses comprising a shell-shaped body  made  from  an  addition-vulcanising two-component silicone rubber mass, which body is enclosed in a plastic sheet sheathing,  and where a filler of fairly low density composed of hollow spheres or microspheres is added to the two-component silicone rubber mass.  The mixture is filled into a sheath of plastic sheet and is cured in a mould under the effect of heat.  To obtain the most uniform distribution possible of the filler in the prosthetic body, the mould is turned continuously through one or two axes before and during the curing of the two-component silicone rubber mass until the silicone rubber is vulcanised to such an extent that any rising of the  filler materials  is prevented.   Alternatively the invention contemplates controlling the viscosity of the two-component silicone rubber mass in order to prevent the light filler from rising before the rubber is cured,  or filler material having the same density as the silicone rubber mass, but which expands under the effects of curing heat, can be used.
