Devices and methods for the treatment of chronic total occlusions are provided. One disclosed embodiment comprises a method of facilitating treatment via a vascular wall defining a vascular lumen containing an occlusion therein. The method includes providing a first intravascular device having a distal portion with a concave side, inserting the first device into the vascular lumen, positioning the distal portion in the vascular wall, and orienting the concave side of the distal portion toward the vascular lumen.
