ABSTRACT:
A method of coating a polymer onto an implant having at least one interstice. The method includes (1) providing a solution containing a polymer; (2) applying the solution onto the implant; (3) and removing the solution spanning the interstice by (a) contacting the outer surface of the implant with a surface of a substrate, so that the solution spanning the interstice is drawn to the surface of the substrate via affinity between them; or by (b) bursting and removing the solution spanning the interstice on the implant with an air pressure difference before drying; and (4) drying the solution to form a coating.
