Cobalt – Chromium Stent System
“Performance delivered with success”
Designed to perform and quickly become the stent of choice even in the most
challenging cases of interventional cardiologists daily practice. The trusted
CoCr stent alloy is used to ensure outstanding radial strength, high radiocapacity
and biocompatibility providing enchanced trackability and improved pushability,
as well. Its high average burst pressure indicates good stent-to-wall apposition.
Hybrid cell design – MSW technology
- Closed cell ends for good anchoring and open cell mid-section for low metal-to-artery ratioClosed cell ends for good anchoring and open cell mid-section for low metal-to-artery ratio
- Multicellular Sinusoidal Waveform Technology for smooth repetitive oscillation to disperse forces more uniformly.
- 2.25-2.75 mm Small Vessel design
- 3.00-4.00 mm Medium Vessel design
Innovative stent delivery system
- Low profile reinforced shaft design for improved pushability and trackability
- Rontis’ proprietary hydrophilic coating, HiFlow, ensuring low friction forces
- Redesigned semi-compliant balloon providing homogeneous expansion and precise stent deployment
- 2, Platinum-Iridium marker bands for lower crossing profile and precise positioning
- No dog-boning effect
Soft tip
- Low profile, true 0.016’’, short and tapered atraumatic soft tip facilitates easier access across the tightest lesion
Folding pleating technology
- Fully automated tri-folding process for increased flexibility, lower balloon primary crossing profile and enhanced rewrap for minimal secondary profileFully automated tri-folding process for increased flexibility, lower balloon primary crossing profile and enhanced rewrap for minimal secondary profile
- Partially encapsulated stent with balloon material due to stent retention technology combining heat and pressure
