Description

The R-Stent sirolimus-eluting coronary stent is intended to expand the lumen of the coronary arteries and reduce the risk of restenosis, and to treat coronary lesions with a diameter from 2.24 to 4.0 mm.

Ultra-thin struts (65 µm) reduce the risk of late stent thrombosis
Ultra-low crossing profile (~1.0 mm) for improved flexibility and deliverability
Increased radial strength gives reliable vessel-wall support and reduces recoil (<5%) for a stable result after implantation
A thin 3 µm bioresorbable polymer coating reduces the risk of vessel inflammation
The coating technology keeps the polymer intact after stent expansion and ensures controlled drug release

Contraindications apply. Read the instructions for use or consult a specialist.
