A tissue/organ retraction or displacement sponge comprising a rigid dry absorbent shaped sponge body (10, 20, 30, 40) constructed of laminated layers (14, 16) of sponge material with differing pore size density causing differing swelling rates and expansion. The sponge when hydrated substantially expands protecting an organ or moving the same to be a different area.
