Artificial breast implant provided on the surface threof with silicon open cell foam layer, and method for producing the same

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.

Problems solved by technology

Although the saline filled artificial breast prosthesis ensures safety of a user even if the filling material leaks into the human body after rupture of the shell as a result of using sterile saline as the filling material, and is easy to change the volume of a breast by adjusting the injection amount of saline, the saline filled artificial breast prosthesis is significantly deteriorated to the touch after surgery as compared to other artificial breast prostheses and the shell thereof has inferior durability.

However, in the case of the hydro-gel filled artificial breast prosthesis, safety with respect to long term use has not been established, volume change depending on the lapse of time and occurrence of wrinkles may increase after the artificial breast prosthesis is inserted into the human body, and feeling is unnatural as compared to a silicone gel filled artificial breast prosthesis.

At present, the above described hydro-gel filled artificial breast prostheses are not distributed on the market on the basis of the year 2000 due to problems in relation to the proof of safety.

This prosthesis has caused gel bleed and capsular contracture, but a rupture speed thereof was relatively low due to the use of the thick shell.

First, in the case of rupture, an event in which Dow Corning sold the prosthesis was bankrupted due to rupture of a great amount of the second generation silicone gel filled artificial breast prosthesis using a thin shell is well-known.

Second, capsular contracture is a natural biological rejection reaction in which collagen films are firmly accumulated around a prosthesis, after insertion of the implant
