CrossBoss and Stingray Catheter and Entera Guidewire Chronic Total Occlusion (CTO) Study

January 24, 2021 updated by: Boston Scientific Corporation

This study is to determine if the BridgePoint Medical System (CrossBoss Catheter, Stingray Catheter, Entera Guidewire) can facilitate safe and effective placement of a guidewire in the true lumen of coronary vessels distal to a chronic total occlusion (CTO).

The hypothesis is that the BridgePoint Medical System can do this without an increase in major complications.
