ABSTRACT:
The flexible needle stop includes a normally unfolded needle impenetrable needle barrier formed of a flexible foldable material. The flexible foldable material can be a single layer sheet material, a wire mesh material and/or one or more layers of scale-like components arranged side by side. The scale-like components are physically unconnected and of a size that permits flexion of the needle stop that incorporates the scale-like components. The flexible needle stop member can include a bead-like periphery which affords the needle stop member with a resilient memory and helps restore the needle stop member to its normally unfolded condition after a folding restraint is removed. The needle stop can be freely disposed within a fill chamber of a tissue expander, attached to an inner surface of the fill chamber or incorporated in the shell wall of a tissue expander.
