Currently available stents were designed for straight lesions, optimised to provide scaffolding (coverage and radial strength) and ease of deliverability. 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.
