Guide extension catheters and related methods are disclosed. A guide extension catheter can comprise an elongate tube member, a push member, and a removable support member. The push member can be eccentrically coupled directly or indirectly to the elongate tube member and can extend proximally therefrom for slidably positioning the elongate tube member within and partially beyond a distal end of a guide catheter. The removable support member can comprise a structure that surrounds at least a portion of the push member. The removable support member alone, or when placed over the push member, can be more rigid along its longitudinal axis than the elongate tube member and can have a cross-sectional dimension that is greater than a maximal cross-sectional dimension of the push member.

Catheter devices, assemblies and related methods for percutaneous crossing of an occlusion in a blood vessel are disclosed. A catheter device can include a central catheter, two side tubes, and a distally-protruding, curved subintimal guidewire. The central catheter can define a central lumen that extends from a proximal end to a distal end of the central catheter. The lumen can be configured to receive a primary guidewire. The central catheter can also define at least one reentry aperture oriented transverse to the central lumen. The first and second side tubes can be coupled with the central catheter, extending along a longitudinal axis thereof, with the first side tube flanking an opposite side of the central catheter relative to the second side tube. The subintimal guidewire can extend from the first side tube, distally beyond the distal end of the central catheter, to the second side tube.
