Biguard™ Sirolimus-eluting Coronary Bifurcation Stent System Accurate positioning, specially designed for treating bifurcated coronary disease Structure: • Stent plantform: Partner™ stent-based platform, local structural improvements. • Opening structure: three axial sinusoidal curve for the bifurcated blood vessel opening structure. • Developing markers: made of 99.99% gold, convenient for positioning at a vascular bifurcation. Features: • Direct effect on the bifurcated vascular disease. • To avoid the proximal stent silk bifurcation openings covering insufficiency and opening overlap seriously. • Precise positioning can be achieved through developing markers of the bracket itself. • The trouble of three structure rotational positioning can be avoided. • Simplify the implantation process, reduce the time of surgery. • Rapamycin drug-eluting effectively inhibit restenosis.
