Abstract: A non-rotating anatomical-shaped breast implant having a front side with a smooth surface and a rear side with a textured surface. A smooth surface ripples or wrinkles little, if at all. Rippling or wrinkling of the implant may undesirably produce a visible or palpable waviness on the skin of the breast. A smooth surface is more likely to produce the look and feel of a natural breast. A rear side with a textured surface is desirable because tissue growth of the body, after the implant has been implanted, engages the textured surface to anchor the implant in place such that the front side with the smooth surface remains matched with the front side of the body and such that the anatomical-shaped breast implant with its tear drop shaped fullness remains at a natural position within the breast. The disclosure further includes a method for minimizing the rotation of an implant within the body and a method for making an implant envelope that has different thicknesses.
