Hybrid-stent design: Why?
Open-cell stents provide better conformability to
the arterial wall and a more “elegant”
angiographic result
Closed-cell stents provide better embolic protection.

Unique Hybrid-Stent Design
• The fixation segment: open cells design in the distal and proximal
segment, to enhance the flexibility respect the anatomy.
• The therapeutic/functional segment:The therapeutic/functional segment: closed cells designclosed cells design in the middle part with in the middle part with optimal scaffolding, to obtain the appropriate wall optimal scaffolding, to obtain the appropriate wall coverage and wall support coverage and wall support

Two Tantalum marker:
1.enhanced visibility in follow-up procedures
2.secure mounting of the markers thanks to Laser-welding
3.inside orientation to reduce mechanical stress in the stent

The Delivery System
Full length braided sheath design
This reinforcement combines pushability and flexibility to enable easy negotiation in tortuous anatomies without kinking
PTFE coating inside the sheath Reduction of friction between sheath and stent
for a gradual, controlled and safe deployment of the stent in the lesion
