Brief summary

TRYTON Post Approval Study (PAS) of the Tryton Side Branch Stent

Detailed description

The primary objective of this PAS is to assure the continued safety and effectiveness of the Tryton Side Branch Stent™ with main branch approved DES in the treatment of de novo native coronary artery bifurcation lesions with side branch diameter ranging from ≥2.5 mm to ≤3.5 mm and main branch diameter ranging from ≥2.5 mm to ≤4.0 mm.

Inclusion criteria

General Inclusion Criteria 1. The patient must be ≥18 and ≤ 90 years of age; 2. Acceptable candidate for CABG; 3. The intention to treat the side branch of the target bifurcation based on angiographic evaluation 4. The patient is willing to comply with specified follow-up evaluations; 5. The patient or legally authorized representative has been informed of the nature of the study, agrees to its provisions and has been provided written informed consent, approved by the appropriate Institutional Review Board (IRB). 6. Planned use of FDA approved and commercially available drug-eluting stents (DES) for subject's index procedure Angiographic Inclusion Criteria 7. a) Single de novo lesion in a bifurcation involving both the main branch and the side branch b) The bifurcation: main branch and side branch with a visual diameter stenosis ≥ 50% (Medina classification 1.1.1; 0.1.1; 1.0.1) by visual assessment; 8. Target lesion located in a native coronary artery; 9. a) Bifurcation lesion main branch reference vessel diameter must be ≥2.5 mm to ≤ 4.0 mm, and b) Side branch reference vessel diameter must be ≥2.5mm by visual estimate (≥2.25mm by QCA) and \<3.5 mm by visual estimate (\<3.25 mm by QCA); 10. a) Bifurcation lesion main branch lesion length ≤ 28 mm and b) Side branch lesion length ≤ 5.0 mm (the ability to be treated with a single stent for both main and side branch); 11. Target lesion ≥50% and \<100% stenosed by visual estimate in both the main branch and side branch; -
