VasoStar Vibrational Guidewire System to Facilitate Crossing Coronary Artery Chronic Total Occlusions

Inclusion Criteria: * Male or female, over 18 years of age, presenting with at least one ischemia inducing lesion in a native coronary artery that is refractory to standard guidewire crossing. Chronic total occlusion (CTO) is defined as 100% coronary blockage for over a 3-month duration documented either by prior catheterization or by clinical evaluation * Suitable candidate for non-emergent, coronary angioplasty * Documented de-novo or restenotic coronary chronic total occlusion defined as a lesion with TIMI 0 flow for at least 90 days refractory to conventional guidewire crossing * Left ventricle ejection fraction \> 20% within the last 12 months. * For antegrade chronic total occlusion procedures, activated clotting time (ACT) should be \> 300 sec * Chronic total occlusion in a non-tortuous arterial segment * Voluntarily sign a Patient Informed Consent Form specific to the study. * Physically and mentally willing to comply with all study requirements. Exclusion Criteria: * Successful target lesion crossing with a conventional wire system prior to enrollment * Prisoners. * Pregnancy * Patient has an active implantable. * Extensive dissection created by refractory guidewire * Severe ongoing congestive heart failure (New York Heart Association Class IV symptoms) * Active infection * Uncontrolled Hypertension (Systolic blood pressure \> 180 mm) at the time of the procedure * History of severe reaction to contrast media * Recent myocardial infarction (within 2 weeks) * In-st…
