Catheters, systems, and methods for bypassing an occlusion

A system for bypassing an occlusion, comprising:

• a first catheter, comprising:
• a first catheter body;
• a first tip positioned at a first distal end of the first catheter body;
• a first guidewire lumen extending through the first catheter body and first the tip of the first catheter, wherein a first central axis of a first distal opening of the first guidewire lumen of the first catheter is parallel to a first longitudinal center line of the first catheter;
• a second guidewire lumen extending through the first catheter body and the first tip of the first catheter, wherein a second central axis of a second distal opening of the second guidewire lumen of the first catheter is angularly offset from the first longitudinal center line of the first catheter;
• and
• a first magnet positioned along the tip of the first catheter;
• and
• a second catheter, wherein:
• the first catheter is configured to be positioned in a subintimal space of a blood vessel;
• and
• the second catheter is configured to be positioned in a lumen of the blood vessel.

• and
• advancing a guidewire through the first guidewire lumen of the first catheter, through the first distal opening of the first guidewire lumen of the first catheter, and into the second distal opening of the second guidewire lumen of the second catheter.
