ASAHI SION®Product Code (REF): AHW14R001S
ASAHI SION is the wire that defined the modern coronary frontline guidewire category. Its ACT ONE (Asahi Composite Technology ONE) construction fuses a tapered stainless-steel core to a coil-wound tip, producing 1:1 torque transmission — rotation applied at the hub is delivered directly to the tip with no lag or magnification — and a bend-retention profile that resists kinking and prolapse in tortuous or calcified coronary anatomy. The 0.7 gf tip load and 28 cm hydrophilic coating position it as the balanced choice for the majority of elective and urgent PCI cases where neither extreme softness nor high penetrating force is required. No other coronary guidewire has been cited as a comparator in as many PCI and CTO publications. Its predictability and reproducibility make it the starting point for most operators' wire escalation strategy: if SION cannot cross, the anatomy calls for a more specialised tool. Within the SION family, the 0.5 gf SION Blue offers a softer option for fragile side branches, while the 0.8 gf SION Black adds tip force for moderately resistant lesions — but SION itself covers the widest range of cases. SION is available in straight and J tip configurations in both 180 cm standard and 300 cm exchange lengths. All variants share the same 0.36 mm outer diameter, 28 cm coil-wound segment, and 3 cm radiopaque distal length.
Available under product codes AHW14R001S, AHW14R301S, AHW14R001J, AHW14R301J.

Request DocumentationFrequently Asked Questions
- What is ASAHI SION® and why is it considered the benchmark coronary guidewire?
- ASAHI SION® is a 0.014 in coronary frontline guidewire built on the ACT ONE (Asahi Composite Technology ONE) platform — a tapered stainless-steel core fused to a coil-wound tip that delivers 1:1 torque transmission and kink resistance. It is the most widely cited comparator wire in CTO and complex PCI clinical literature, used as the standard against which all other coronary guidewires are measured in terms of trackability, tip response, and procedural predictability.
- What is the tip load of ASAHI SION®?
- ASAHI SION® has a tip load of approximately 0.7 gf (gram-force). This places it between SION Blue (≈ 0.5 gf, softer for side branches) and SION Black (≈ 0.8 gf, firmer for moderate lesion resistance), making it the balanced choice for the majority of workhorse PCI cases.
- What are the catalog numbers for ASAHI SION®?
- ASAHI SION® is available in four catalog configurations: AHW14R001S (Straight, 180 cm), AHW14R301S (Straight, 300 cm), AHW14R001J (J tip, 180 cm), AHW14R301J (J tip, 300 cm). All share a 0.36 mm outer diameter, 28 cm coil length, and 28 cm hydrophilic coating.
- What is ACT ONE construction and why does it matter?
- ACT ONE (Asahi Composite Technology ONE) is the proprietary shaft design used in the SION family. It fuses a tapered stainless-steel core directly to a coil-wound tip, eliminating the mechanical joint that causes torque lag in conventional guidewires. The result is genuine 1:1 torque transmission — one full rotation at the hub produces exactly one rotation at the tip — enabling precise steering in tortuous or calcified anatomy.
- When should I choose ASAHI SION® versus SION Blue or SION Black?
- ASAHI SION® is the standard choice for the majority of PCI cases: elective single-vessel disease, multi-vessel PCI, moderately tortuous anatomy, and as the first wire in CTOs before escalation. SION Blue (0.5 gf) should replace SION when the target is a fragile side branch, small distal vessel, or bifurcation PCI where tip trauma must be minimized. SION Black (0.8 gf) should replace SION when the lesion has mild resistance that SION cannot penetrate but does not yet require a dedicated CTO wire.
- Is ASAHI SION® available in a 300 cm exchange length?
- Yes. ASAHI SION® is available in 300 cm exchange length in both straight (AHW14R301S) and J tip (AHW14R301J) configurations. The 300 cm length is used when over-the-wire device exchanges must be performed without removing the guidewire from the coronary artery.
- Where can I order ASAHI SION®?
- ASAHI SION® is available globally through Asahi Intecc's authorised distributor network. Modern Medical Solutions is the authorised Asahi Intecc distributor for Tajikistan and Afghanistan.
