The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government.
Read our disclaimer for details.
This is a prospective, multi-center, non-randomized, single arm clinical trial that will be conducted at up to 40 sites in the United States and Outside United States (OUS). This study will enroll patients with symptomatic ischemic heart disease due to a single de novo lesion contained within a native coronary artery with reference vessel diameter between 2.5 mm and 4.0 mm and lesion length ≤ 24 mm that is amenable to percutaneous coronary intervention (PCI) and stent deployment. All patients will be followed at 30 days, 6 months, 9 months, 1 year and annually for 5 years post index stenting procedure.
The primary endpoint will be the incidence of Target Vessel Failure (TVF) within 270 days of treatment with the COBRA PzFTM Coronary Stent System.

Accepts Healthy Volunteers:
General Inclusion Criteria:
Patient >/= to 18 years old.
Eligible for percutaneous coronary intervention (PCI).
Patient understands the nature of the procedure and provides written informed consent prior to the catheterization procedure.
Patient is willing to comply with specified follow-up evaluation and can be contacted by telephone.
Acceptable candidate for coronary artery bypass graft (CABG) surgery.
Stable angina pectoris (Canadian Cardiovascular Society (CCS) 1, 2, 3 or 4) or unstable angina pectoris (Braunwald Class 1-3, B-C) or a positive functional ischemia study (e.g., ETT, SPECT, Stress echocardiography or Cardiac CT).
Male or non-pregnant female patient (Note: females of child bearing potential must have a negative pregnancy test prior to enrollment in the study).
Angiographic Inclusion Criteria
Patient indicated for elective stenting of a single stenotic lesion in a native coronary artery.
Reference vessel >/= 2.5 mm and </= 4.0 mm in diameter by visual estimate.
Target lesion </= 24 mm in length by visual estimate (the intention should be to cover the whole lesion with one stent of adequate length).
Protected left main lesion with >50% stenosis.
Target lesion stenosis >/= 70% and < 100% by visual estimate.
Target lesion stenosis <70% who meet physiological criteria for revascularization (i.e. positive FFR).
General Exclusion Criteria:
Currently enrolled in another investigational device or drug trial that has not completed the primary endpoint or that clinically interferes with the current study endpoints.
Previously enrolled in another stent trial within the prior 2 years.
ANY planned elective surgery or percutaneous intervention within the subsequent 3 months.
A previous coronary interventional procedure of any kind within 30 days prior to the procedure.
The patient requires staged procedure of either the target or any non-target vessel within 9 months post-procedure.
The target lesion requires treatment with a device other than PTCA prior to stent placement (such as, but not limited to, directional coronary atherectomy, excimer laser, rotational atherectomy, etc.).
Previous drug eluting stent (DES) deployment anywhere in the target vessel.
Any previous stent placement within 15 mm (proximal or distal) of the target lesion.
Co-morbid condition(s) that could limit the patient's ability to participate in the trial or to comply with follow-up requirements, or impact the scientific integrity of the trial.
Concurrent medical condition with a life expectancy of less than 12 months.
Documented left ventricular ejection fraction (LVEF) < 30% within 12 months prior to enrollment.
