A radially self-expanding stent (10) is disclosed that is circumscribed with a matrix (15) of flexible polymeric material. This matrix (15) provides a barrier to tissue and/or tumor ingrowth. A deployment device (20) for the stent (10) includes an interior tube (30) on which the stent (10) may be placed and a hose (55) folded on itself surrounding and compressing the stent (10) on the interior tube (30).
