Eligibility

Inclusion Criteria:

• Adult aged 25-80
• Patient understands and has signed the study informed consent form.
• Patient is a suitable candidate for non-emergent, coronary angioplasty
• Patient has an angiographic documented Chronic Total Occlusion (i.e. >3 months occlusion duration either by documentation or PI assessment Investigator) showing distal TIMI flow 0.
• Coronary angiography of CTO lesion reveals satisfactory distal vessel visualization
• CTO lesion is located in a coronary vessel with a reference diameter of at least 2 millimeters.

• Intolerance to Aspirin and/or inability to tolerate a second antiplatelet agent (Clopidogrel and Prasugrel and Ticagrelor).
• Appearance of a fresh thrombus or intraluminal filling defects.
• Recent major cerebrovascular event (stroke or TIA within 30 days)
• Significant anemia (hemoglobin < 8.0 mg / dl)
• Unstable angina requiring emergent percutaneous trans-luminal coronary angioplasty (PTCA) or coronary artery bypass graft (CABG)

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Cardiovascular Adverse Events (Primary Safety)	Accumulative incidence of Major Adverse Cardiovascular Events (MACE), defined as the composite of death, myocardial infarction (MI), or urgent revascularization (target vessel revascularization (TVR) or urgent coronary artery bypass surgery (CABG)).	30 days
Primary	Technical Success (Primary Efficacy)	Intra-procedural technical success, defined as the ability of the NovaCross™ microcatheter to successfully facilitate placement of a guidewire beyond a native coronary chronic total occlusion in the true vessel lumen	1 day
Secondary	Procedural Success	The ability to cross the lesion with a guidewire in the true lumen, effectively dilate the CTO lesion, and place a coronary stent with residual lumen stenosis of less than 30% while restoring antegrade TIMI 3 flow	1 day
Secondary	Assistance in Guidewire Penetration	The ability of the NovaCross™ micro-catheter to facilitate a guidewire successfully penetrating the proximal cap of the CTO	1 day
Secondary	Crossability	The effectiveness of the extendable portion in intra-CTO microcatheter crossability	1 day
Secondary	Procedual Visualization	The ability to have full visualization of the NovaCross during the CTO procedure	1 day
Secondary	Operator Ease of Use	Assess the usability of the NovaCross™ by the operator	1 day
Secondary	Device Related Perforation Rate	Device-related perforation at the site of target coronary lesion and/or its proximal reference segment	1 day
