Abstract
Tissue expansion system includes a pump, a controller, and inflatable bladder, and a pressure sensor. The pump is adapted for substantially continuous operation in response to a pressure within a subcutaneously implanted inflatable bladder. The pump is thus able to deliver inflation medium to the bladder when the pressure within the bladder is below a predetermined lower threshold while stopping delivery of the fluid when the pressure rises above a higher threshold or reaches a predetermined maximum volume.
