ASAHI SION® blueProduct Code (REF): AHW14R004S
ASAHI SION® Blue is the soft-tip member of the SION family, engineered on the same ACT ONE (Asahi Composite Technology ONE) platform that made SION the most referenced frontline coronary guidewire in PCI literature. Where the standard SION delivers a balanced 0.7 gf tip load suited to the majority of workhorse cases, SION Blue drops to approximately 0.5 gf — reducing tip stiffness by roughly 30% while preserving every other ACT ONE shaft property: 1:1 torque transmission, a coil-wound radiopaque distal segment, and the predictable bend retention operators rely on for shape memory. This lower tip force makes SION Blue the preferred choice when the goal is atraumatic first-pass access rather than pushability. It excels in side-branch wire placement during bifurcation PCI, distal wiring in highly tortuous or calcified anatomy where tip prolapse risk is elevated, and jailing techniques where the wire must remain passively seated in a small branch under balloon inflation. The 42 cm silicone + hydrophilic tip coating provides low-friction, controlled advancement without the full slipperiness of a dedicated hydrophilic wire — striking the balance needed for side-branch access rather than CTO probing. SION Blue is available in straight and J tip configurations across 180 cm standard and 300 cm exchange lengths, covering routine, complex and extended-reach cases.
Available under product codes AHW14R004S, AHW14R304S, AHW14R004J, AHW14R304J.

Request DocumentationFrequently Asked Questions
- What is ASAHI SION® Blue and how does it differ from SION and SION Black?
- ASAHI SION® Blue is the softest-tip member of the SION coronary guidewire family. All three share the same ACT ONE (Asahi Composite Technology ONE) construction — a tapered stainless-steel core fused to a coil-wound tip — but differ in tip load: SION Blue ≈ 0.5 gf, SION ≈ 0.7 gf, SION Black ≈ 0.8 gf. SION Blue is chosen when atraumatic first-pass access is the priority; SION Black is preferred when moderate lesion resistance needs to be overcome.
- What is the tip load of ASAHI SION® Blue?
- ASAHI SION® Blue has a tip load of approximately 0.5 gf (gram-force), making it the softest-tip wire in the SION series. This is roughly 30% lower than the standard SION (≈ 0.7 gf) and significantly lower than SION Black (≈ 0.8 gf), giving it the gentlest first-pass feel while still providing the 1:1 torque response of the ACT ONE shaft.
- What are the catalog numbers for ASAHI SION® Blue?
- ASAHI SION® Blue is available under four catalog numbers: AHW14R004S (Straight tip, 180 cm), AHW14R304S (Straight tip, 300 cm), AHW14R004J (J tip, 180 cm), and AHW14R304J (J tip, 300 cm). All variants have a 0.36 mm (0.014") outer diameter, 20 cm coil length, and 42 cm silicone + hydrophilic coating.
- What coating does ASAHI SION® Blue use?
- ASAHI SION® Blue uses a combined silicone and hydrophilic coating over a 42 cm length from the tip. The silicone component provides controlled friction for tactile feedback during side-branch wiring, while the hydrophilic section reduces resistance in tight, tortuous anatomy — a balance that distinguishes it from fully hydrophilic CTO wires.
- When should I choose ASAHI SION® Blue over the standard ASAHI SION®?
- SION Blue is preferred when the procedural objective is atraumatic first-pass access: side-branch wiring during bifurcation PCI, wiring fragile or small-calibre distal vessels, or jailing techniques where the wire must sit passively in a small branch under balloon inflation. The standard SION is appropriate for the majority of workhorse cases where a slightly firmer tip is beneficial. For moderately resistant lesions, SION Black offers a further step up in tip force.
- Is ASAHI SION® Blue suitable for bifurcation PCI and kissing-balloon techniques?
- Yes. ASAHI SION® Blue is widely used for side-branch access in bifurcation PCI. Its low 0.5 gf tip load minimises the risk of side-branch ostium trauma during initial wiring, and the wire's stable ACT ONE shaft allows it to be re-crossed or re-wired after stent deployment. The 42 cm silicone + hydrophilic coating aids navigation through the stent struts into the side branch.
- Is ASAHI SION® Blue available in a 300 cm exchange-length variant?
- Yes. ASAHI SION® Blue is available in both 180 cm standard length and 300 cm exchange length. The 300 cm variants (AHW14R304S straight, AHW14R304J J-tip) are used when device exchanges over the wire are required without wire removal, such as in complex PCI procedures with multiple balloon-catheter exchanges.
- Where can I order ASAHI SION® Blue?
- ASAHI SION® Blue is distributed globally through Asahi Intecc's authorised regional partners. Modern Medical Solutions is the authorised Asahi Intecc distributor for Tajikistan and Afghanistan.
