摘要：
Embodiments of the invention are directed towards a rapid exchange catheter configured for insertion into a subintimal space and crossing an occlusion in a subintimal space. The catheter includes a proximal end, a distal end, a first lumen configured to receive a first wire, the first lumen extending longitudinally through a least a lateral port of the catheter, and a second lumen having at least a portion distal of the lateral port and extending through at least the distal end of the catheter. The catheter also includes an exchange port, arranged on an exterior portion of the catheter configured to receive a second wire and second rapid exchange port in communication with the second lumen. Moreover, other embodiments of the invention are directed towards methods for using the rapid exchange catheter to cross an obstruction in a vessel, e.g., a total or partial occlusion, in a subintimal space.
