Outcome Measures

Primary Outcomes (2)

  • Number of participants with successful crossing of the target lesion with the VasoStar guidewire system

    1 day

  • Incidence of Treatment-Emergent Serious Adverse Events

    Number of device- or procedure- related serious adverse events

    30 days

Secondary Outcomes (6)

  • Improved 6-minute walk distance at 6 months following the VasoStar successful procedure

    6 months

  • Improved 6-minute walk distance at 12 months following the VasoStar successful procedure

    12 months

  • Improved score on the Seattle Angina Questionnaire at the 6-month visit compared to the score at baseline

    6 months

  • Improved score on the Seattle Angina Questionnaire at the 12-month visit compared to the score at baseline

    12 months

  • Reduced number of hospitalizations for cardiac symptoms within 1 year following the VasoStar procedure, compared to the reported number of hospitalizations following standard CTO procedures.

    1 year

  • +1 more secondary outcomes

Study Arms (1)

VasoStar guidewire system

EXPERIMENTAL

The VasoStar guidewire system will be used to cross vascular occlusion lesions.

Device: VasoStar guidewire system

Interventions

The VasoStar Vibrational Guidewire System vibrates longitudinally at the distal segment of a wire with an electromagnetic source.

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

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
