Claims

1. A breast implant system comprising at least one casing (3, 4) with a flexible outer shape for implantation in a patient's body so as to form part of a breast implant (10) and further comprising at least one first element (1) contained in the casing and optionally at least one second element (2) also contained in the casing and even further comprising a lubricating fluid for reducing surface friction between an outer surface of said at least one first element (1) and surfaces contacting said outer surface, characterized by a reservoir (R; R'; R"; R"') comprising said lubricating fluid and connected to the casing (3, 4) so as to allow lubricating fluid to be supplied to and removed from the casing.
  2. The breast implant system of claim 1, wherein the lubricating fluid is a liquid or a gel, which is preferably isotonic.
  3. The breast implant system of any of claims 1 and 2, adapted to change the friction between surfaces in the breast implant to allow a change of the outer shape of the breast implant post-operatively and, preferably, non-invasively.
  4. The breast implant system of any of claims 1 to 3, wherein the outer surface of the at least one first element (1) or of at least two or at least three first elements (1) is displaceable relative to a contacting inner surface of the casing and/or relative to a contacting outer surface of the at least one second element (2).
  5. The breast implant system of any of claims 1 to 4, wherein the reservoir (R; R'; R"; R"') is adapted for implantation inside the patient's chest area, preferably outside the thorax, more preferably below the minor pectoralis muscle (40) or between the major and the minor pectoralis muscles (40, 41).
  6. The breast implant system of any of claims 1 to 5, wherein the reservoir is adapted for implantation within the patient's body remote from the breast implant (10), the system further comprising at least one conduit (5) between the remotely implantable reservoir and the casing for fluid exchange between the reservoir and the casing, wherein preferably at least part (R"') of the reservoir (R) is adapted to be implanted in the armpit or underneath the patient's arm or in the patient's abdominal cavity.
  7. The breast implant system of claim 6, wherein at least part (R"') of the reservoir (R) is adapted to be implanted subcutaneously such that fluid can be exchanged between the casing and the reservoir by manually compressing the subcutaneously implanted reservoir (R) or part (R"') thereof, thereby urging fluid to flow from the reservoir into the casing.
  8. The breast implant system of any of claims 1 to 7, comprising at least one valve (28) between the reservoir and the casing, wherein the at least one valve (28) preferably includes a pressure relief valve which opens in at least one direction at a predetermined pressure.
  9. The breast implant system of any of claims 1 to 8, comprising 10 or more, preferably 100 or more of the first elements (1) contained in the casing (3, 4).
  10. The breast implant system of any of claims 1 to 9, wherein the outer wall of the casing has a shape adapted to allow lengthening of the functional length thereof without interfering with fibrosis covering said outer wall, when the breast implant is implanted in the body, wherein the outer wall preferably has at least one wrinkle or cease adapted to allow lenghtening of the outer wall without lenghtening fibrosis covering the outer wall when implanted.
  11. The breast implant system of any of claims 1 to 10, wherein at least one first element (1) and at least one second element (2) within the casing are interconnected so as to allow for exchanging content between them.
  12. The breast implant system of any of claims 1 to 11, wherein the outer surface of the at least one first element (1) is displaceable relative to a contacting outer surface of the at least one second element (2) by moving the first element between different spots within the casing (3, 4) so as to change the outer shape of the breast implant (10).
  13. The breast implant system of any of claims 1 to 12, wherein the exchange of an amount of fluid between the reservoir and the casing (3, 4) involves a displacement of an amount of fluid between sub-chambers (R", R"') of the reservoir, said amount being different to the amount of fluid exchanged between the casing (3, 4) and the reservoir.
  14. The breast implant system of any of claims 1 to 13, further comprising at least one pump (13), wherein the at least one pump (13) is adapted for exchanging lubricating fluid between the reservoir (R) and the casing (3, 4) and/or for pumping fluid between the first and second elements.
  15. The breast implant system of claim 14, further comprising a control unit (C1, C2) adapted to directly or indirectly control the at least one pump (13) or another component of the system, wherein the control unit (C1, C2) is preferably adapted to be operable by the patient from outside the patient's body.
