Abstract

A breast implant comprising a plurality of bags filled with a fluid and each having, when at rest, a predetermined configuration. Each of the bags is defined by a flexible membrane. A means, particularly an outer shell, is provided to hold the bags together.

Claims

1. A breast prosthesis comprising:

a plurality of pockets filled with a liquid, wherein each of said pockets has, at rest, a predetermined configuration, and each of said pockets is delimited by a flexible membrane; and

a holding device for holding said pockets against one another, wherein said pockets are formed integrally with one another so as to form at least one string.

2. The breast prosthesis as claimed in claim 1, wherein said flexible membranes of said pockets, which are held in mutual contact, adhere to one another.

3. The breast prosthesis as claimed in claim 1, wherein said holding device comprises a flexible outer envelope defining an interior space in which said pockets are contained.

4. The breast prosthesis as claimed in claim 3, wherein said flexible outer envelope is hermetically sealed and a portion of said interior space, defined between said flexible outer envelope and said pockets, is filled with a liquid.

5. The breast prosthesis as claimed in claim 1, wherein all of said pockets are substantially identical.

6. The breast prosthesis as claimed in claim 1, wherein each of said pockets has a substantially spherical shape.

7. The breast prosthesis as claimed in claim 1, wherein each of said pockets has an elongate shape, and said pockets are rolled up on themselves.

8. The breast prosthesis as claimed in claim 1, wherein each of said pockets is hermetically sealed.

9. The breast prosthesis as claimed in claim 1, wherein each of said pockets is equipped with at least one calibrated opening to permit circulation of said liquid.

10. The breast prosthesis as claimed in claim 9, wherein said pockets are connected to one another by a fine conduit connecting said circulation openings so as to form at least one string of communicating pockets.

11. The breast prosthesis as claimed in claim 10, wherein said flexible outer envelope is hermetically sealed and a portion of said interior space defined between said envelope and said pockets is filled with liquid, and said at least one string of communicating pockets has opposite ends which are open.

12. The breast prosthesis as claimed in claim 10, wherein said pockets and said conduits of said at least one string are delimited by the same flexible membrane.

13. The breast prosthesis as claimed in claim 1, wherein said at least one string comprises a plurality of strings which are rolled up on themselves.

14. The breast prosthesis as claimed in claim 1, wherein said flexible membranes of said pockets are made of silicone elastomer.

15. The breast prosthesis as claimed in claim 1, wherein said liquid comprises a physiological serum.
