Nano+™ Polymer-free Sirolimus-eluting Coronary Stent System

Nano+™ Polymer-free Sirolimus-eluting Coronary Stent System

Nothing Beats Free

Product Description

  • Nanoporous cavities on strut abluminal surface functioning as drug carrier to ensure the firm adhesion.
  • Vacuum drug coating technology ensures complete drug dosage and coating stability.
  • Post-treatment after drug loading helps with sustained drug release.

Polymer-free Stent

  • Soft tapered tip provides smooth transition from guidewire to balloon catheter and excellent crossability.
  • Short shoulder design at both ends of the balloon ensures the accurate dilation to the lesion, and reduces the damage to normal vessel next to the lesion.
  • Patented hydrophilic coating on distal shaft provides outstanding pushability.


  • Polymer-free design significantly reduces the inflammatory response after stent implantation to guarantee the long-term safety.
  • Polymer-free design facilitates earlier endothelialization which significantly shorten the DAPT time.
  • The rough strut surface helps with earlier and easier endothelialization to reduce the risk of thrombosis.

An OCT Study in Europe Shows Nano+™ A Great Combination of DES Efficacy and BMS Safety [3]. 

In a prospective, multicentre, single-arm, open-label study, OCT examinations  were performed at three months in 45 patients (47 lesions). 23 patients with 24 lesions had serial coronary angiography and OCT assessment at three and six months.

Coverage Status Of The Individual Stents/Patients At Two Time Points (Three And Six Months)

Coverage status of the individual stents/patients at two time points (three and six months).

Serial OCT showed almost complete vascular healing at six months, even when coverage was insufficient at three months. This suggests an adequate safety and efficacy profile of the device at that point in time.
