The present invention provides a lumen support stent with a clear through-lumen for use in a body lumen. The methods comprise adsorbing volatilized PGM in at least one PGM trapping material, which is disposed on a third substrate monolith disposed between the first substrate monolith and the second substrate monolith. The coaxial region can be formed by a portion of the second limb being disposed in a volume of the first limb, which allows for a low profile construct that is useful in various soft tissue repair procedures. Seams positioned between adjacent conductors have a textured surface pattern, and seams positioned along edges of the flat electrical cable have a substantially smooth surface pattern. In the meantime, the suspected offending item may be analyzed. The seat member comprises first and second plugs engageable with the seat engagement portions of the first and second leg members, respectively.
