Abstract:
1. An implantable tissue expander comprising: an integrally formed, resiliently deformable, internal skeletal element extending between a flat base surface and an outer surface, the outer surface having a convex shape encompassing the entire outer surface, and including at least one plurality of non-random elongate cells extending longitudinally along mutually parallel axes from said base surface to said outer surface and being defined by elongate cell walls formed of a resilient human-implantable material; and a sealed enclosure, sealing said internal skeletal element and configured to prevent body fluids from filling said plurality of non-random elongate cells; wherein the skeletal element is temporarily and resiliently deformable in that after being deformed to reduced dimensions, the base and the outer surface are able to regain their flat and convex configurations, respectively, by virtue of the resiliency of the skeletal element.
