Brief summary
A prospective, open label, multi-center, single arm, observational study designed to evaluate the acute safety and device procedural success of the Scoreflex NC Scoring Percutaneous Transluminal Coronary Angioplasty (PTCA) catheters in subjects with stenotic coronary arteries during percutaneous coronary intervention. Two-hundred (200) subjects will be treated at up to 15 U.S. sites with the Scoreflex NC Scoring PTCA catheter during their index procedure. All subjects will be screened according to the protocol inclusion and exclusion criteria and will be followed through hospital discharge.
Interventions
To dilate coronary arteries during the subject's index procedure with Scoreflex NC Scoring PTCA catheters
