Abstract
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.
