<p>The present invention relates to a process for manufacturing implants or intermediate products of such implants, in particular breast implants, comprising
a) providing an implant shell comprising cured or uncured silicone, in particular having a front side, a back side and a region bridging said front and back side,
b) if need be, subjecting the uncured silicone of said implant shell to at least one curing step, in order to undergo complete or partial vulcanization, and applying at least one uncured additional silicone layer to the implant shell so obtained,
c) placing a first foam sheet over at least part of the uncured implant shell, in particular over the front side, the region bridging said front and back side and at least part of the back side of the implant shell, as provided in step a) or as obtained in step b),
d) subjecting the implant shell obtained in step c) to at least one curing step in order to vulcanize the uncured silicone of step a) or of the additional uncured silicone layer of step b) and, if need be, the silicone of the implant shell not cured yet, thereby bonding the first foam sheet to the implant shell,
e) if need be, remove excess foam sheet not bonded by curing in step d) to the back side of the implant shell, and
f) apply at least one sheet comprising partially or completely uncured silicone to the back side of the implant shell, thereby in particular covering those parts not covered by the first foam sheet.</p> |
