摘要: 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.

摘要: A method of reconstructing tissue is provided. The method includes implanting an absorbable tissue expander having a fluid-tight or semipermeable envelope and 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 has an injection port for the controlled inflation and deflation of the envelope after the device is implanted in a tissue. The method also may include a plurality of envelopes.
