Seven years of CRAFT: clinical results of a multicenter cohort of carotid artery relining with the CASPER RX stent.

Background And Purpose: Carotid artery stenting (CAS) is an established treatment for carotid stenosis or occlusion. Use of the dual-layer microporous CASPER RX stent has had mixed results in prior reports. The CaRotid Artery Filtering Technique (CRAFT) uses the distal end of the CASPER stent as an embolic protection device during deployment.
