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

This study has been completed.

BridgePoint Medical Identifier:
First received: December 2, 2008
Last updated: December 2, 2009
Last verified: December 2009

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.
