Tryton侧枝支架是由Tryton医疗公司(Newton, MA, USA)研制开发的，被设计用于治疗冠状动脉分杈病变。该支架使用独特的气囊扩张，5个French兼容系统通过单一导线输送。 当与当前使用的标准导管共同使用治疗主要血管病变的时候，该系统能够在侧枝处提供效果更好覆盖和环状束缚力。Tryton侧枝支架当前仅用于研究目的。

　　在正在使用冠状动脉支架的患者中，大约有25％发生位于侧枝处的冠状动脉疾病。但是，药物释放支架的设计并不能完全治疗这些患者。放置在分杈处的支架目前会发生更多的急性并发症和远期的再狭窄。
 
　　Stent Designed Specifically for Bifurcations
 
　　A new coronary stent being developed for the treatment of bifurcation lesions has been used clinically for the first time.

　　The Tryton side-branch stent, being developed by Tryton Medical (Newton, MA, USA), is designed to treat coronary artery arterial lesions involving a bifurcation. The stent is a unique balloon expandable, 5 French compatible system that is delivered with a single wire. When used in conjunction with any existing standard stent for the main vessel, it provides superior coverage and hoop strength to the origin of the side-branch. The Tryton side branch stent is currently for investigational use only.

　　Coronary artery disease located at the branch of arteries occurs in up to 25% of patients currently undergoing coronary stenting. However, the designs of available drug-eluting stents do not adequately address this group of patients. Stents placed at bifurcations are currently associated with higher acute complications as well as late restenosis.
