In straight lesions, these stents have been shown to provide superb acute and long-term results. One lesion subset that continues to challenge the interventionalist is bifurcations lesions. A number of different strategies have been employed with standard stents to address bifurcation lesions each of which have significant limitations. Large contemporary registries characterising current stent usage in bifurcating lesions have demonstrated decreased procedural success with increased rates in restenosis and thrombosis (acute, subacute and delayed). The limitations of currently available stents have led groups to develop stents designed specifically to treat bifurcation lesions. The Tryton Side-Branch Stent Stent TM (Tryton Medical, Inc., Newton, MA, USA) is a balloon expandable cobalt chromium stent, designed specifically to treat bifurcation lesions.\n\nThe primary objective of this study is to evaluate the safety and feasibility of the use of the Tryton bifurcation coronary stent system for the treatment of single de novo bifurcation lesions in native coronary arteries with reference vessel diameters (RVD) for the proximal main vessel of 2.5 - 5.0 mm, distal main branch of 2.5 - 5.0 mm, and side branch RVD 2.5 - 3.5 mm.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'minimumAge': '18 Years', 'healthyVolunteers': False, 'eligibilityCriteria': "Inclusion Criteria:\n\nGeneral Inclusion Criteria\n\n* Candidate for percutaneous coronary intervention \\& emergent coronary artery bypass graft surgery\n* Clinical evidence of ischemic heart disease or a positive functional study\n* Female patients of childbearing potential has negative pregnancy test within 7 days before trial procedure\n* Patient or patient's legal representative provided written informed consent\n* Patient agrees to comply with follow-up evaluations\n\nAngiographic Inclusion Criteria\n\n* Target lesion in a single de novo true bifurcation lesion (Medina classification Type 1.1.1; 1.0.1; 0.1.1; 0.0.1) involving a native coronary artery with reference vessel diameter for the proximal main of 2.5 - 5.0 mm, distal main of 2.5 - 5.0 mm, \\& side branch RVD of 2.5 - 3.5 mm\n* Target lesion in main vessel has stenosis of \\> 50% and \\<100%\n* Syntax score \\< 32\n\nExclusion Criteria:\n\nGeneral Exclusion Criteria\n\n* Known hypersensitivity/contraindication to aspirin, heparin or bivalirudin, clopidogrel or ticlopidine, cobalt, nickel, chromium, molybdenum, or sensitivity to contrast media, which can't be adequately pre-medicated\n* Platelet count \\<100,000 cells/mm³ or \\>700,000 cells/mm³, or a white blood cell (WBC) count \\<3,000 cells/mm³ within 7 days prior to index procedure\n* Serum creatinine level \\>170 micromol/L within 7 days prior to index procedure\n* Evidence of acute MI within 72 hours of intended trial procedure (defined as: QWMI or NQWMI having CK enzymes \\>2X laboratory upper limit of normal in the presence of a confirming cardiac specific biomarker (Troponin I or T)\n* Previous stenting anywhere in target vessel\n* Percutaneous coronary intervention (PCI) of non-target vessel within 30 days prior to procedure that results in any MAC(C)E event.
