ASAHI SION® blackProduct Code (REF): APW14R010S
ASAHI SION® black is the highest tip-load member of the SION frontline family, delivering approximately 0.8 gf — 14% more than the standard SION at 0.7 gf and 60% more than SION Blue at 0.5 gf. It retains the same ACT ONE (Asahi Composite Technology ONE) shaft construction as its siblings — tapered stainless-steel core, coil-wound tip, 1:1 torque transmission — but replaces the hydrophilic PTFE coating with a polymer + hydrophilic tip system that adds column support and reduces shaft slack during rotation. In practice, SION black fills the role of the 'second wire' when the standard SION tracks freely but encounters a lesion segment with moderate resistance it cannot penetrate. The extra tip force is enough to engage calcified plaque or fibrous tissue without escalating to a dedicated CTO wire. It is particularly useful in moderately calcified lesions, ostial RCA disease with fibrous caps, and in any anatomy where an initial soft wire has confirmed a true lumen path but cannot advance. SION black is available in three tip shapes — straight, J, and pre-shape — across 190 cm standard and 300 cm exchange lengths, with a 12 cm coil-wound segment and a 40 cm polymer + hydrophilic coating.
Available under product codes APW14R010S, APW14R310S, APW14R010P, APW14R310P, APW14R010J, APW14R310J.

Design & Technology
Technical characteristics and diagrams as published by Asahi Intecc.
Lubricity
Polymer jacket characteristics allow smooth lesion entry and crossing
Tip flexibility
Compared with conventional polymer jacket wires, ASAHI SION black is flexible laterally. This increases vessel tracking capability in tortuous lesion.
Durability
ASAHI SION black is hardly effected by the curve. Tip durability by ACT ONE helps maintain operability through tortuous vessels.
The above data was obtained by company standardized test, which may differ from industry standardized tests. The data does not prove that all devices have exactly the same performance with the samples used for these tests.

Request DocumentationFrequently Asked Questions
- What is ASAHI SION® black and how does it differ from SION and SION Blue?
- ASAHI SION® black is the firmest-tip member of the SION frontline family at approximately 0.8 gf — 14% more than standard SION (0.7 gf) and 60% more than SION Blue (0.5 gf). It uses the same ACT ONE construction but adds a polymer jacket over much of the shaft for increased column support. SION black is chosen when standard SION tracks freely but encounters mild lesion resistance it cannot penetrate, bridging the gap to dedicated CTO wires.
- What catalog numbers does ASAHI SION® black come in?
- ASAHI SION® black is available in six configurations: APW14R010S (Straight, 190 cm), APW14R310S (Straight, 300 cm), APW14R010P (Pre-shape, 190 cm), APW14R310P (Pre-shape, 300 cm), APW14R010J (J, 190 cm), APW14R310J (J, 300 cm). All have a 12 cm coil segment, 40 cm polymer + hydrophilic coating.
- What is the tip load of ASAHI SION® black?
- ASAHI SION® black has a tip load of approximately 0.8 gf. This is the highest in the SION frontline family and provides enough penetrating force for moderately calcified lesions or fibrous ostial disease where standard SION cannot advance, without requiring escalation to a dedicated CTO wire.
- When is ASAHI SION® black preferred over the standard SION®?
- SION black is preferred when the standard SION tracks successfully to the lesion but cannot penetrate it — typically in moderately calcified segments, fibrous ostial right coronary artery disease, or cases where there is mild resistance that doesn't yet warrant a CTO approach. It is also useful as a 'second wire' when SION Blue has been used for side-branch protection and the main-vessel wire needs more tip force.
- What coating does ASAHI SION® black use?
- ASAHI SION® black uses a polymer jacket over 150 cm of the shaft with a hydrophilic tip over the distal 40 cm. The polymer jacket increases shaft stiffness and pushability compared to the hydrophilic-coated standard SION, contributing to SION black's improved column strength. The coil length is shorter (12 cm vs. 28 cm on standard SION) to concentrate mass at the penetrating tip.
- Does ASAHI SION® black come in a pre-shape tip?
- Yes. Uniquely among the SION family, SION black offers a pre-shape tip configuration (APW14R010P at 190 cm and APW14R310P at 300 cm) in addition to straight and J tips. The pre-shape is used when the operator wants to advance the wire into a specific vessel with a natural bend without manually shaping the tip beforehand.
