VasoStar Vibrational Guidewire System to Facilitate Crossing Coronary Artery Chronic Total Occlusions
Trial Parameters
Brief Summary
The goal of this project is to provide an improvement in wire performance to expedite crossing difficult lesions in the coronary vasculature.
Eligibility Criteria
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: * Successfu
