A piercing catheter comprises a distal tip used to pierce an occlusion in a crossing procedure and can be configured to microdissect the occlusion or provide support for an elongate member. A reentry catheter comprises a distal side port and ramp to facilitate the reentry or perforation of a vessel wall. A multi-lumen, reentry catheter comprises a tearable lumen divider and a distal side port and ramp. 21 6186944_1 (GHMatters) P93255.AU.1 ALANAJ17/22 =4.. C) fo 3.00) OLO) UD =3
