Abstract
A tissue expanding device includes a substantially non-extensible base and a top layer joined to the periphery of the base such that the base and the expansion layer are in contact with each other when the device is in a non-expanded state. In the non-expanded state, the device has a thickness substantially equal to the thickness of the combined thickness of the base and expansion layer.
