Abstract
A recanalization catheter assembly for recanalization of an occluded blood vessel is disclosed. The recanalization catheter assembly includes an elongate shaft having a tubular portion, a guide member, and a rotary ablation tool. The tubular portion includes a distal opening, from where the rotary ablation tool extends distally. The guide member extends distal of the distal opening and includes a guidewire lumen to receive a guidewire therethrough. The guide member is configured to advance over the guidewire in a subintimal space between a first tissue layer and a second tissue layer of a wall of the blood vessel, while the rotary ablation tool is advanced in a true lumen of the blood vessel.
