A tissue expansion device with a plurality of lobes made from non-compliant material, each lobe defining a chamber therein. Each chamber is fluidly isolated from every other chamber in the plurality of lobes. Each chamber has an inflation element with a valve to release a pressurized fluid to inflate the lobe to expand a cavity, and a deflation element with a valve to deflate the lobe by compressing the fluid.
