1. A breast implant shell comprising:

  • a fillable envelope including an open-cell foam element defining an anterior surface of the envelope, the element produced by the steps of;

    a. preparing a foaming solution, the foaming solution comprising an elastomer base and a curing agent;

    b. adding the foaming solution to a mold assembly having a textured surface component having a surface porosity of at least about 40%, a textured surface of the textured surface component being defined by an interconnected array of void space, wherein the foaming solution is added to the mold assembly in a manner sufficient to allow penetration of the foaming solution into the interconnected array of void space;

    c. curing the foaming solution to produce an elastomeric foam material on the textured surface component; and

    d. removing the textured surface component from the elastomeric foam material to obtain a foam material having an open-cell surface.
