20080300681BIOLOGICAL TISSUE GROWTH THROUGH INDUCED TENSILE STRESS - A tissue expansion device implanted in a non-activated state over a region of desired tissue growth. Once implanted and positioned the device is activated creating a supporting structure that creates a convex shaped dome over the underlying tissue.

Alone or with the introduction of tissue enhancing agents and/or adipose tissue, new tissue within the convex shaped void grows until a balance is achieved eliminating the induced stress. Periodically the tissue expansion devices is again activated and enlarged creating an even larger void. Again, the newly enlarged void places additional tensile stress on the underlying tissue thus repeating the cycle of new tissue growth. Once the desired amount of tissue growth has been achieved the device is deactivated and removed.12-04-2008
