DFT Intracranial Stent with Blue-Shield Surface Technology
DFT Intracranial Stent with Blue-Shield Surface Technology
5mm Radiopaque Distal Delivery Wire Tip
Pre-shaped 90°distal tip,re-shapable as needed toaccommodate procedural preference
The distance between the recapture marker and deployment marker on the delivery system is 1.5mm
Repeated resheathing and repositioning are possible as long as the stent is not deployed beyond the recapture marker

Constructed with DFT braided alloy wires
Optimized filament diameter to balance flexibility and radial support
Increased braiding wires in larger diameter sizes to maintain structural integrity
Designed to accommodate tortuous internal carotid segments and complex vascular anatomy
Suitable for distal and bifurcation aneurysms, ruptured and blister-type aneurysms, as well as long-segment dissecting lesions
Enhanced intra-procedural assessment of stent expansion and wallapposition
4 radiopaque markers at both proximal and distal ends to facilitate precise positioning
0.5 mm flared ends (shorter than typical 2mm designs), reducing the non-functional segment and supporting enhanced procedural safety
Larger diameters(4.0-5.5mm)incorporate 20-24 braided wires to enhance structural support and promote reliable expansion in tortuous anatomy
.webp "Optimized braided design to facilitate smooth expansion within tortuous internal carotid segments")
Blue-Shield thermall oxidized surfaceforms a dense titanium dioxide layer that reduces nickelion release and platelet adhesion, supporting improved hemocompatibility and lower thrombus risk
2.5mm diameter(lengths 10/15/20/25mm) deliverable through a 0.017"microcatheter, supporting access to distal vascular lesions
3.5-4.5mm diameters compatible with 0.021" microcatheter systems
4.5-5.5mm diameters deliverable through 0.027" microcatheters
Designed to support coil stabilization during embolization, helping to reduce the risk of coil protrusion into the parent vessel
Particularly suited for wide-neck, ruptured, and blister-type aneurysms
Finer braid filament diameter (0.05mm) compared with conventional 0.06mm braided configurations
Increased mesh density at nominal diameter contributes to enhanced scaffold support
The lantern techniqyue may increase metal coverage at the aneurysm neck to provide protection in bifurcation lesions
It supports effective coil embolization and, in selected cases, may reduce the need foran additional stent compared with dual-stent strategies
