The three types of silicone gel-filled breast implants are as follows:
One type is a single lumen implant that is prefilled by the manufacturer with a fixed volume of silicone gel.
A second type is a double lumen implant with (1) an inner lumen prefilled by the manufacturer with a fixed volume of silicone gel and (2) an outer lumen that is filled during the operation with a fixed volume of saline through a valve.
A third type is a double lumen implant with (1) an outer lumen prefilled by the manufacturer with a fixed volume of silicone gel and (2) an inner lumen that is filled during the operation with saline through a valve. This type of implant allows for adjustments of the saline volume after the operation.
A silicone gel-filled breast implant has a silicone rubber shell with the same general composition as shown in the Saline-Filled Breast Implants section above.
The filler is silicone gel that has the general composition of:
cured polymeric (large) silicones
small amounts of uncured large and smaller silicones
minute amounts (parts per million) of metals, including a metal catalyst (usually platinum). (A catalyst is something that causes a change in material.)
