简要总结

Evaluate the safety and effectiveness of the CapBuster System medical device in crossing de novo or restenotic chronic total occlusions in coronary arteries

详细描述

Primary Efficacy Endpoints:

Successful crossing of the targeted chronic total occlusion, defined as angiography confirmed guidewire placement in the true lumen without utilization of a re-entry device.

The effectiveness endpoint is designed to demonstrate successful crossing of the chronic total occlusion in at least 80% of lesions.

Primary Safety Endpoints:

Freedom from CapBuster System related clinically significant perforation, embolization, or dissection, defined as perforations or embolization that require intervention and flow-limiting (type C, D, E) dissections.

入选标准

  • •Males > 18 years of age and Female patients of non child-bearing potential
  • •Clinical diagnosis of coronary arterial disease requiring revascularization as evidenced by Duplex UltraSound, Digital Subtraction Angiography, CT angiography, or MR angiography
  • •Subject requires single- or multi-vessel percutaneous coronary intervention (PCI) of de novo or restenotic target lesion (including in-stent restenotic lesions).
  • •Subject's lesion(s) is (are) amenable to stent treatment with currently available CE or FDA-approved stents.
  • •Presence of coronary arterial de novo or restenotic chronic total occlusion (100% stenosis), with TIMI 0 flow, confirmed by angiography. Vessel distal to the occlusion(s) must be visualized per collateral or retrograde flow. A maximum of 1 target occlusions can be treated per patient. Target occlusion(s) can be in-stent restenosis
  • •Target vessel(s) must be ≥ 2.5 mm and ≤ 3.25 mm in diameter proximal to the target occlusion(s) by visual estimate
  • •In the opinion of the investigator, life expectancy of > 1 year
  • •Willing and able to sign the informed consent form

排除标准

  • •Target occlusion is within a bypass graft
  • •acute coronary syndrome with ST elevation,
  • •cardiogenic shock or out of hospital cardiac arrest
  • •Subject has signs or symptoms of systemic infection/sepsis (temperature ≥38.0o Celsius and WBC ≥12,000 cells/uL). If subject has localized infection, including cellulitis or osteomyelitis, or infection is adequately treated and controlled, per investigator discretion, patient may be enrolled.
  • •Known or suspected myocardial infarction or stroke within previous 30 days
  • •Currently participating in another investigational drug or device study
  • •Female patients of child-bearing potential.
  • •Evidence of STEMI within 72 hours of the intended treatment on infarct related or non-infarct related artery.
  • •Cardiogenic shock on presentation or during current hospitalization.
  • •Known allergies or contraindication to: contrast materials, antiplatelet therapy, aspirin, clopidogrel (Plavix) and ticlopidine (Ticlid), heparin, bivalirudin, stainless steel, or contrast agent (which cannot be adequately premedicated).
  • •Subject is currently participating in an investigational drug or device study that has not completed the primary endpoint or that clinically interferes with the current study endpoints. (Note: Trials requiring extended follow-up for products that were investigational, but have since become commercially available, are not considered investigational trials).
  • •Stroke or transient ischemic attack within the prior 3 months.
  • •Any target vessel that has evidence of excessive thrombus (e.g. requires target vessel thrombectomy).
  • •Any target vessel that has evidence of excessive tortuousity (greater than 60 degree angle) that makes it unsuitable for proper stent delivery and deployment,
  • •Any target lesion that requires treatment with a device other than percutaneous transluminal coronary angioplasty (PTCA) prior to stent placement (e.g. but not limited to, directional coronary atherectomy, excimer laser, rotational atherectomy, etc.).
