Abstract: Intraluminal devices are provided with an inner cavity. The inner cavity may be loaded with a bioactive substance. Fenestrations extend between an outer surface and the inner cavity. Thus, the bioactive substance may be released from the intraluminal device through the fenestrations.

Abstract: A bi-directional steerable guidewire having a deflectable distal tip which comprises a longitudinal hypotube and a spring coil attached to the distal end of the hypotube and also includes a longitudinally movable deflection member which is attached to the distal end of the spring coil and a tip retaining member which extends from the distal end of the hypotube to the distal end of the spring coil for providing very precise deflection of the distal tip.
