Abstract

Provided are methods for making textured implantable materials made from two part RTV silicone foams and having a desired color or tone without the need for dyes or colorants.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . A method of making a material having a preselected color and suitable for implantation in a mammal, the method comprising:
 providing a silicone base component;   providing a catalyst for the base component; and   mixing the base component with the catalyst at about 50 rpm for about 30 seconds to achieve a foam solution; and   allowing the foam solution to polymerize to achieve a polymerized silicone foam material having a bronze brown tone having RGB color code values R=about 184 to about 225, G=about 114 to about 140, and B=45 to about 55.   
     
     
         2 . The method of  claim 1  that excludes the addition of any colorant, dye or similar agent. 
     
     
         3 . The method of  claim 1  wherein the viscosity of the foam solution is between about 4300 mPas to about 4700 mPas. 
     
     
         4 . The method of  claim 1  wherein the viscosity of the foam solution is about 4500 mPas. 
     
     
         5 . An implantable material useful as a component of a breast implant made by the method of  claim 1 . 
     
     
         6 . A method of making a breast implant shell comprising:
 providing a silicone base component;   providing a catalyst for the base component; and   mixing the base component with the catalyst at about 50 rpm for about 30 seconds to achieve a foam solution; and   allowing the foam solution to polymerize to achieve a polymerized silicone foam material having a bronze brown tone having RGB color code values R=about 184 to about 225, G=about 114 to about 140, and B=45 to about 55.   
     
     
         7 . The method of  claim 6  that excludes the addition of any colorant, dye or similar agent. 
     
     
         8 . The method of  claim 6  wherein the viscosity of the foam solution is between about 4300 mPas to about 4700 mPas. 
     
     
         9 . The method of  claim 6  wherein the viscosity of the foam solution is about 4500 mPas. 
     
     
         10 . An implantable material useful as a component of a breast implant made by the method of  claim 6 .
