The purpose of this study is to examine the treatment of coronary Bare Metal Stent restenosis with a drug coated AngioSculpt scoring balloon.

Prospective, controlled, multicenter, randomized, single-blind trial. The aim is to examine the treatment of coronary Bare Metal Stent restenosis with a drug coated AngioSculpt scoring balloon. Patients are randomized to treatment by an AngioSculpt scoring balloon (no drug coating)or a drug coated AngioSculpt scoring balloon (paclitaxel 3.0 µg/mm²). Primary efficacy endpoint is late lumen loss in-segment at 6 months. Key secondary endpoints include procedural Success, MACE (cardiac death, target vessel myocardial infarction, and clinically driven target lesion revascularization at 6 months). Individual clinical endpoints include stent thrombosis (ARC), cardiac death, any death, target vessel myocardial infarction, any infarction, clinically driven target lesion revascularization, clinically driven target vessel revascularization, any revascularization.

Inclusion Criteria:

• >18 years of age
• clinical evidence of stable or unstable angina or a positive functional study
• patients with ≤ 2 primary in-stent restenosis (ISR) lesions (≥ 70% diameter stenosis) within previously placed bare metal stents (BMS)

Exclusion Criteria:

• acute myocardial infarction within the past 72 hours
• chronic renal insufficiency with serum creatinine levels >2.0 mg per deciliter%
• known hypersensitivity or contraindications to aspirin, heparin, clopidogrel, ticlopidine or paclitaxel, and sensitivity to contrast media not amenable to premedication
• concomitant medical illness associated with a life-expectancy of less than two years
• stented segment length ≥30 mm, vessel diameter <2.5 mm, diameter stenosis <70%
