  • Patent number: 10085831
    Abstract: Disclosed are an artificial breast implant in which the surface thereof is formed or modified with a silicone open cell (open pore) foam layer, and a method for producing the same. More specifically, disclosed are an artificial breast implant that has a surface including an open cell foam layer made of silicone and thus minimizes side effects such as in vivo rejection, which may occur after implantation of the implant into the body, in particular, the occurrence of capsular contracture to achieve superior biocompatibility and safety, and a method for producing the same.

  • Patent number: 9408692
    Abstract: A silicone prosthesis including a silicone shell, which has superior texture and comfort when implanted in the body, minimizes stress concentration that may arise when wearing for a long time by eliminating the difference in physical characteristics and stress in all parts of the shell, due to the silicone prosthesis having a uniform thickness, increases resistance to fatigue fracture so as to maximize the safety and lifespan of the silicone prosthesis, and which controls the flow of the silicone in various angles, thereby providing a round or an anatomical type silicone prosthesis having a shell with enhanced durability and a uniform thickness.

  • Patent number: 9132004
    Abstract: The present invention relates to a silicon breast implant which minimizes stress concentration applied thereto after being inserted into the human body to maximize the resistance of same to fatigue-induced rupture, thereby improving the durability of the implant. The breast implant may include an elegant patch-adhesion portion having a thin thickness so as to provide superior overall feel and improve the appearance of the product. Further, the breast implant has a silicon shell defining an outer wall thereof and the patch adhesion portion for closing, from the outside, a hole formed in a bottom surface of the silicon shell so that the patch adhesion portion is increased in strength to maximize adhesion durability, safety of use, and effectiveness. The silicon shell has a uniform overall thickness, and the patch adhesion portion comprises a patch hole through which a patch adheres to a lower end of the silicon shell using an adhesive material.

  • Patent number: 8480736
    Abstract: The present invention relates to an artificial breast prosthesis which minimizes stress concentration and to a production method therefore, and more specifically relates to an artificial breast prosthesis which has excellent mechanical properties, superior tactile texture, and excellent safety and efficacy as a breast prosthesis, and also relates to a production method therefore. The artificial breast prosthesis made with the production method of the present invention, comprises a silicone shell which is of the same thickness as the connecting portion and has the same or similar physical properties thereof, and which minimizes the concentration of the stresses sustained after insertion into the body and maximizes resistance to fatigue failure such that durability is improved while at the same time the thinness of the connecting portion provides an outstanding texture to the prosthesis as a whole, and safety and efficiency are improved as stress concentration is minimized.
