Abstract
An improved skin expansion device includes an inflatable envelope fluidly connected through a base thicker than the envelope to a conduit in fluid connection with an injection chamber. The base fluidly connects the conduit to the inflatable envelope through at least one fluid channel extending between a position proximate the perimeter of the base to an inwardly disposed location in fluid communication with the interior of the inflatable envelope. The conduit is connected to the base along the perimeter and in fluid communication with the fluid channel.
