Study Arms (1)
VasoStar guidewire system
EXPERIMENTALThe VasoStar guidewire system will be used to cross vascular occlusion lesions.
Interventions
The VasoStar Vibrational Guidewire System vibrates longitudinally at the distal segment of a wire with an electromagnetic source.
Eligibility Criteria
You may qualify if:
- 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.
You may not qualify if:
- 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-stent target lesion
- Severe cerebrovascular disease including history of prior stroke or transient ischemic attack within 1 month at the time of the procedure
- Saphenous vein graft (SVG) chronic total occlusion or an in-stent chronic total occlusion
- Short life expectancy due to other illnesses such as cancer or pulmonary, hepatic or renal disease
- Participation in another investigational protocol at the time of the procedure
