Asahi SION® blue Coronary Guidewire AHW14R004S
The Asahi SION® blue AHW14R004S is a 0.014-inch frontline coronary guidewire designed to deliver smooth handling, balanced support, and dependable vessel navigation during PCI procedures. Asahi describes SION blue as a first-choice frontline guidewire built to meet a wide variety of clinical needs while maintaining the performance of the SION platform.
The AHW14R004S configuration is the straight-tip, 180 cm version of the SION blue guidewire. Official Asahi product information lists this model with a 0.36 mm (0.014") outer diameter, 20 cm coil length, 3 cm radiopaque segment, and silicone + hydrophilic coating. Product tables for this exact reference also identify it as a straight-tip frontline wire with a 180 cm usable length.
Asahi positions SION blue as a well-balanced workhorse wire with proprietary construction intended to provide greater tip flexibility, durability, and torque response. The company also notes that the wire has a lighter distal tip than standard SION and a slightly modified coating profile that reduces lubricity somewhat, which Asahi says can allow safer control in the vessel.
The straight-tip AHW14R004S model is well suited to physicians who prefer a standard frontline wire shape for coronary vessel selection, lesion access, and support during device delivery. That final sentence is an inference based on the straight-tip configuration and Asahi’s positioning of SION blue as a frontline coronary guidewire.
Built for interventional cardiology workflows, the Asahi SION blue AHW14R004S is intended to facilitate placement of balloon dilation catheters during PTCA and PTA procedures, making it a practical option for routine and complex coronary navigation where balanced torque, visibility, and control are essential.
