Breast implant system

A breast implant system having a size and shape adapted to either replace a natural breast that has been removed or increase the size of a natural breast, the breast implant system comprising:

• a plurality of chambers including at least one first fluid chamber and at least one second fluid chamber,
• said at least one first fluid chamber and said at least one second fluid chamber being adapted for implantation in a human body, with the at least one first fluid chamber having a flexible outer wall and forming part of one breast implant,
• said at least one first fluid chamber and said at least one second fluid chamber being interconnected when implanted, such that fluid can be exchanged from the at least one first fluid chamber to the at least one second fluid chamber and vice versa so as to change their respective fluid contents, and, thus, the shape of the breast implant after its implantation, wherein at least one of the at least one first and the at least one second fluid chambers is adapted to allow an increase in its volume and at least a second one of the at least one first and the at least one second fluid chambers is adapted to allow a decrease in its volume and wherein said fluid chambers only fill a part of the breast implant, whereas a major part of the breast implant is filled with a material which is not provided for fluid exchange, and
• a pump adapted to be implanted in the human body for pumping fluid between the at least one first fluid chamber and the at least one second fluid chamber.
