摘要:
The present invention provides methods and apparatuses for crossing or bypassing total or near total occlusions of vessels through the use of elongate members and specialized catheters that include a piercing catheter, a reentry catheter, a multilumen, reentry catheter, and combinations thereof. 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.
