Fabrication of a monorail-type diagnostic catheter for rescue retrieval technique of a distal embolic protection device.

In this technical report, we describe a challenging case concerning the retrieval of a distal embolic protection device (DEPD) post-carotid artery stenting. We propose a novel rescue retrieval technique for DEPD, employing a fabricated monorail-type HN5 diagnostic catheter. When integrated with existing strategies, this approach may optimize and streamline the process of DEPD removal.
