| 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 said chamber and deflatable upon removal of the fluid from said chamber. The tissue expander also has a means for the controlled inflation and deflation of the envelope after the device is implanted in a tissue. |
