Partner™ Sirolimus-eluting Coronary Stent System The successful delivery of efficacy and safety through the combination of a proven drug and a reliable polymer A Proven Drug Maximum DES Efficacy Over 5 years of proven clinical application experience • Effective anti-restenosis and anti-inflammatory properties. A Reliable Polymer Long-term Safety • Advanced polymer-coating technology provides ptimally controlled releasing of sirolimus that efficaciously inhibits intimal hyperplasia and restenosis. ’ PBMA/PEVA coating is a widely used biocompatible coating that provides an ideally controlled drug release. Only 6 pm thickness of polymer, thinner coating increases deliverability of stent. Advanced Stent Design High Confidence Delivery Proprietary DOUBLE-HELIX stent structure is engineered for outstanding flexibility and conformability. • Optimal thickness of stent strut provides favorable balance between radial strength and deliverability. 36 mm length makes it easy to achieve full coverage of long lesion.
