Abstract
Methods for texturing surgical implants, for example, breast implants, are provided. The methods include the use of computer controlled 3D printing of a sacrificial material to create a textured surface on an unfinished surface of the implant.
Claims20
A method for creating a textured surface on a breast implant, the method comprising:
- providing a breast implant shell;
- applying a first tacky layer onto the shell;
- using a three-dimensional printing process to deposit a texturing material onto the first tacky layer to form a micrometer-scale pattern for creating an imprint on the first tacky layer;
- curing the first tacky layer to form a first cured, imprinted layer;
- removing the texturing material from the tacky first cured, imprinted layer to obtain a textured surface that facilitates cell ingrowth on the textured surface;
- after removing the texturing material from the first cured, imprinted layer, applying a second tacky layer onto the first cured, imprinted layer;
- depositing, via three-dimensional printing, additional texturing material onto the second tacky layer to form a second micrometer-scale pattern for creating a second imprint on the second tacky layer;
- curing the second tacky layer to form a second cured, imprinted layer;
- and
- removing the texturing material from the second cured, imprinted layer to obtain a second textured surface that facilitates cell ingrowth on the second cured, imprinted layer.

A method for creating a textured surface on a breast implant, the method comprising:
- providing a breast implant shell;
- and
- repeatedly forming a pattern of textured layers on the shell, each layer being formed by (i) applying a tacky silicone layer onto the shell, (ii) using a three-dimensional printing process to deposit a texturing material in a predetermined pattern for leaving an imprint onto the tacky silicone layer, (iii) curing the silicone layer to create a cured, imprinted silicone layer, and (iv) removing the texturing material from the cured, imprinted silicone layer to obtain a textured surface that facilitates cell ingrowth on the textured surface.
A method for creating a textured surface on a breast implant, the method comprising:
- applying a first tacky layer onto a breast implant shell;
- forming a first micrometer-scale pattern on the first tacky layer using sugar and a solid freeform fabrication (SFF) or layer manufacturing (LM) technique;
- curing the first tacky layer to form a first cured, imprinted surface;
- removing the sugar from the first cured, imprinted surface;
- after removing the sugar from the first cured, imprinted surface, applying a second tacky layer onto the first cured, imprinted surface;
- forming a second micrometer-scale pattern on the second tacky layer using sugar and a solid freeform fabrication (SFF) or layer manufacturing (LM) technique;
- curing the second tacky layer to form a second cured, imprinted surface;
- and
- removing the sugar from the second cured, imprinted surface to obtain a second textured surface that facilitates cell ingrowth on the implant.
