The present invention is concerned with a method of manufacturing a tissue-integration device, and a tissue-integration device so produced, the method comprising the steps of wrapping a porous sheet of material around a mandrel in order to create overlapping layers of the porous sheet material, the wrapped mandrel then being placed in a mould in order to apply pressure and heat to the overlapping layers in order to effect the lamination thereof such as to form a device having spaces defined by overlapping pores of the adjacent layers.
