An endoluminal prosthesis (20) comprises a first membrane (25) having a lumen (29) for allowing fluid flow, and a stent (38-68) having contracted and expanded states. At least one surface enhancement member (27, 28), separate from the stent, is secured to the stent prior to a coaxial overlapping state of the stent and the first membrane. The at least one surface enhancement member has stronger bonding properties with the first membrane, relative to bonding properties of bare surfaces of the stent with the first membrane, when the stent and the first membrane are in the coaxially overlapping state.
