Abstract:
1. A process for manufacturing a two-layer breast prosthesis comprising the steps of: a) providing: (i) a first film envelope configured to define a first interior volume; and (ii) a second film envelope joined to the first film envelope along a common side edge to thereby define a second interior volume wherein said second film envelope and said first film envelope share a common interstitial film wall and wherein said first and said second film envelopes further comprise a respective first and a second fill opening extending from the common side edge to the respective first interior volume and second interior volume; b) at least partially filling the second interior volume of step a) by passing a curable elastic material precursor through the second fill opening; c) at least partially filling the first interior volume of step a) by passing a self-shaping dispersion through the first fill opening, wherein air is removed from the self-shaping dispersion prior to passing the self-shaping dispersion through the first fill opening; d) sealing the first and second fill openings; and e) curing the elastic material precursor in the second film envelope to provide a two-layer breast prosthesis comprising a cured elastic material layer and an uncured self-shaping layer.
