Brief summary
A multicenter, randomized, controlled, superiority clinical trial to evaluate the efficacy and safety of drug-eluting peripheral arterial stent system(G-stream) in the treatment of femoropopliteal artery stenosis or occlusion.
Detailed description
To evaluate the efficacy and safety of the drug-eluting peripheral arterial stent system(G-stream) in the treatment of superficial femoral artery and/or proximal popliteal artery. Taking the drug eluting balloon catheter (AcoArt-Orchid) as control.
Interventions
Sirolimus drug-eluting self-expanding stent available from 20mm to 250mm in length, 3.5mm to 7.5mm in diameter of superficial femoral and proximal popliteal arteries (SFA/PPA) cases for inhibiting in-stent restenosis and improve long-term outcome.
A proprietary lipophilic coating technology that uses magnesium sterate as excipient, facilitates paclitaxel transfer to the vessel wall, enhances drug delivery, and brings minimal downstream effect. Available from 20mm to 300 mm in length, 3mm to 12 mm in diameter, fits every SFA cases, reduces radiation exposure time.
