Abstract
A recanalization catheter assembly and method for establishing a subintimal pathway around an occlusion in a blood vessel. The recanalization catheter assembly an inflatable balloon structure including a distal anchoring portion configured to expand within a true lumen portion of the blood vessel distal of the occlusion to anchor the recanalization catheter from unintentional movement during expansion of a stent in the subintimal pathway. The expandable stent, such as a bioabsorbable stent, may be configured to promote native tissue regrowth around the stent to create a superficial intimal layer along the subintimal pathway.
