Clinical Data

Facilitated Antegrade Steering Technique in Chronic Total Occlusions

The FAST-CTO trial demonstrated the safety and efficacy of the CrossBoss and Stingray Coronary CTO Crossing and Re-Entry devices to recanalize coronary CTOs in comparison to historical controls.

  • Multi-center, non-randomized US IDE study
  • 147 patients in 16 centers

Safe and Effective

Use of the CrossBoss and Stingray Crossing and Re-Entry devices result in a high technical success, 77%, without increasing complications.1

Reduced Procedure Time

Procedural success was improved with a 28.1% reduction in mean procedure time (minutes) as well as a reduction in fluoroscopy time.1

Primary Endpoints
