A surgical implant namely a tissue expander or adjustable implant having a synthetic mesh loosely attached to the surface. The mesh is elastic in all directions and the implant adjustable or expandable. The expandable implant is filled to an over filled volume into the surrounding tissue until a new capsule forms.
