TM Nano+ Polymer-free Sirolimus-eluting Coronary Stent System Efficacy of DES, safety of BMS The efflcacy of DES Nano+ stent, in which is used the effective and widely applied Sirolimus. with drug-coating and special technical post-treatment. would guarantee high drug loading density and Ideal drug release kinetics. At the surface of Nana, nanoporcus cavity as drug carrier Smaller cavity has stronger adhesion of drug. More than 80% surface porosity guarantees firm adhesion. Nanoporous cavity does not attest the macroscopic properties at Stent. The high etfectlve drug loading dosage of Nano+ “‘ polymer-free stent: 2.2 ug/mm2 The safety of EMS Nano+ m stent adopts the Polymer-tree drug-loading technology. Only bare metal stents is left after the complete release of drug. There Is no polymer coating that could cause Inflammatory response. Nano+ 7” stent improves the adhesion. extension and proliferation of endothellal cells, and facilitates complete healing of vessel intima A newer and more advanced balloon delivery system Small tapered tlp design. patented hydrophlllc coating on the shaft provides excellent deliverebiiity over the torturous anatomy.
