Textured breast implant and methods of making same
First Claim
Patent Images
1. 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.

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.

1. 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. - View Dependent Claims (2, 3, 4, 5, 6, 7, 8, 9, 10, 11)

12. 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. - View Dependent Claims (13, 14, 15)

16. 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. - View Dependent Claims (17, 18, 19, 20)
