Abstract: A method of manufacturing a laminated item such as a prosthesis or tissue expander having a flexible, expandable membrane surrounding an interior lumen to enhance the strength and performance of the membrane comprises the steps of applying a first layer of a fluid, resilient, stretchable material to a mandrel; allowing the fluid material to drain off the mandrel in a first flow direction; allowing the fluid material to harden to form a resilient, stretchable first layer on the mandrel; applying a second layer of the fluid material on the first layer; changing the orientation of the mandrel to allow the fluid material to drain off the mandrel in a second flow direction, the second flow direction being at an angle to the first flow direction; and allowing the fluid material to harden to form a resilient, stretchable second layer on the first layer.
