First Claim
Patent Images
1. A shell for an inflatable breast implant, the shell comprising:
- a wall comprising a particle/matrix composition comprising an elastomeric silicone polymer matrix defining enclosed spaces, and discontinuous particles of a swellable material occupying the enclosed spaces in the matrix;
wherein, when the wall is contacted with an aqueous fluid, the particles of swellable material enlarge within the enclosed spaces such that the wall becomes self-sealing to a needle puncture.
