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 a exterior portion of the catheter configured to the 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.

(canceled)37. A rapid exchange catheter system , comprising:a shaft having an inner lumen and an exchange port fluidly coupled with the inner lumen, the exchange port arranged on a distal portion of the rapid exchange catheter system, and the inner lumen and the exchange port configured to receive a first wire; anda rigid shroud coupled to the shaft on the distal portion of the rapid exchange catheter system, the rigid shroud comprising a second lumen and a lateral port fluidly coupled with the second lumen, the second lumen and the lateral port configured to receive a second wire;wherein, as viewed from an end view of the rapid exchange catheter system, the exchange port is exterior of the rigid shroud.38. The rapid exchange catheter system of claim 37 , further comprising a cannula disposed within the lumen claim 37 , the cannula configured to extend from the lateral port and receive the second wire.39. The rapid exchange catheter system of claim 37 , wherein the exchange port is disposed proximally relative to the rigid shroud.40. The rapid exchange catheter system ...

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. 1. A method for forming a pathway in an interstitial space within a blood vessel and lumen of the blood vessel , comprising the steps of:advancing a first wire into the interstitial space;advancing a rapid exchange catheter system over the first wire into the subintimal space;advancing a second wire down a central lumen of the rapid exchange catheter system; andadvancing the second wire through a lateral port of the rapid exchange catheter system into the lumen of the blood vessel.2. The method of claim 1 , further comprising the step of orientating the lateral port of the rapid exchange catheter to be aligned with the lumen of the blood vessel.3. The method of claim 2 , wherein the lateral port has an exit orientation arranged at about ninety degrees from a longitudinal axis of the catheter.4. The method of claim 1 , wherein the step of advancing the second wire comprises the steps of:advancing a cannula over the second wire into the lumen of the blood vessel; andadvancing a second wire through a lumen of cannula into the lumen of the blood vessel.5. The method of claim 1 ...
