A prospective, single-treatment, multi centre clinical trial enrolling 30 patients in 2 centres in Romania, with a clinical and angiographic follow-up at 4 and 9 months to determine the primary endpoint of late lumen loss and secondary endpoints. A subgroup of 15 patients will also undergo post implantation, 4 and 9 months IVUS examinations. Additional clinical follow-ups take place at 1 month and yearly up to three (3) years.

The objective of this trial is to assess the safety and clinical performance of the ORSIRO drug eluting stent in patients with single de-novo coronary artery lesions.

  • In-segment late lumen loss [ Time Frame: 4 and 9 months post procedure ] [ Designated as safety issue: No ]
  • In-stent late lumen loss [ Time Frame: 4 months post procedure. ] [ Designated as safety issue: No ]
  • Target Lesion Revascularization [ Time Frame: 1, 4 and 9 months and at 1, 2 and 3 years post-procedure ] [ Designated as safety issue: Yes ]

Enrollment: 30

Primary Completion Date: April 2010 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
ORSIRO Device: ORSIRO - Drug Eluting Coronary Stent
The coronary stent is delivered to the intended implantation location by means of the fast-exchange delivery system and then expanded to its final diameter by dilating the balloon. It remains in the vessel as a permanent implant.


Ages Eligible for Study:   18 Years to 80 Years
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  1. Patient is ≥18 years old;
  2. Clinical evidence of ischemic heart disease and / or a positive functional study. Documented stable angina pectoris (Canadian cardiovascular society classification (CCS) 1, 2, 3 or 4 ), or documented silent ischemia;
  3. Single de novo lesion with ≥50% and <90% stenosis in 1 coronary artery;

Exclusion Criteria:

  1. Documented left ventricular ejection fraction (LVEF) ≤30%;
  2. Unstable angina pectoris(Braunwald Class A I-III)
  3. Three-vessel coronary artery disease
  4. Evidence of myocardial infarction within 72 hours prior to the index procedure;
  5. Known allergies to the following: Acetylsalicylic acid (ASA) (Aspirin®), Clopidogrel bisulfate (Plavix®.) or Ticlopidine (Ticlid®.), Heparin, contrast agent (that cannot be adequately premedicated), cobalt-chromium (CoCr), Poly-L-Lactidic Acid (PLLA), silicon carbide (aSiC:H)

  8. Total occlusion (TIMI 0 or 1);
  9. Target vessel has evidence of thrombus or is excessively tortuous that makes it unsuitable for proper stent delivery and deployment;
  10. Significant (>50%) stenosis proximal or distal to the target lesion that might require revascularization or impede run off;

  12. Target lesion is located in or supplied by an arterial or venous bypass graft;
  13. Ostial target lesion (within 5.0mm of vessel origin);
