Abstract
The invention relates to an absorbable implantable tissue expander device that can be used in surgeries as a gradually diminishing space filler. The absorbable tissue expander has a fluid-tight or semipermeable envelope having a bio-absorbable biocompatible shell defining a chamber. The envelope is inflatable upon infusion of a fluid into the chamber and deflatable upon removal of the fluid from the chamber. The tissue expander also enables the controlled inflation and deflation of the envelope after the device is implanted in a tissue.
