1. A method for creating a textured surface on a workpiece, the method comprising:
- a) providing a workpiece having a surface;
b) applying particles of a solid polymeric material to at least a portion of the surface to create a particle covered portion of the surface;
c) applying a polymer dispersion to at least the particle covered portion of the surface to create a coated surface;
d) applying particles of a solid polymeric material to at least a portion of coated surface; and
e) applying a polymer dispersion to at least the particle covered portion of the coated surface.

Abstract
A method for forming a randomly textured surface on an implantable device such as soft tissue prosthesis. The textured surface has numerous cavities, interstices and passageways or tunnels and is thus referred to as a microporous surface texture. The surface is formed by tow or more applications of polymeric particles and a polymeric dispersion.
