Micromesh stent technology – also a solution for peripheral ? Dr Daniel Périard Hôpital Cantonal Fribourg Switzerland Disclosure

I have no potential conflict of interest regarding this presentation. RoadSaver ™ carotid stent

It is a double layer of braided nitinol wires The outer layer provides high radial force, flexibility and conformation to tortuous anatomy The inner micromesh layer has the smallest cell size, preventing plaque protrusion and 5Fr rapid exchange platform Fully re-sheathable and repositionable Ongoing studies evaluating the Roadsaver ™ for CAS

30 days primary patency 100% 30 days freedom from TLR 100% 30 days freedom from TVR 96% *

patients n=15 6 months primary patency 100 % 6 months in stent restenosis (PSV≥2) 0 % * recanalisation of a lesion proximal to the Roadsaver 84 y woman, rutherford 4

Immediate result of the Roadsaver™ implantation no restenosis at 6 months Duplex

The Roadsaver ™ may be used as a for small poplitea . High plaque coverage operates as a metallic covered stent, but keeps the side branch open

76 y man, rutherford 3 Roadsaver™ used of the as a scaffold for aneurysm and the stenosis and preserved flow in flow diverter for the stent and the the aneurysm side branch

Popliteal calcified stenosis with post- stenotic small aneurysm

day 0 day 18 conclusions

Innovative dual layer stent with excellent scaffold for SFA/pop calcified lesions. Safe Ease of use Absence of restenosis at 6 months Candidate for popliteal aneurysm cure (flow diverter) Further studies must confirm these results
