Abstract
A vascular occlusion-crossing assembly (2) includes an elongate delivery system (4) and a flexible elongate member (6) which passes along the body (34) of the delivery assembly. A laterally-extending, vascular tunica-separation guide (32) helps guide the distal end (36) of the delivery assembly between tunica layers (40, 42, 44) to a position distal of an occlusion (52). The distal portion (30) of a distally moving elongate member, typically a flexible hollow needle, is deflected into this distal lumen (54) on the far side of an occlusion (52). A guidewire (62) may be passed along the elongate member thereby crossing the occlusion.
