The ASAHI SION blue ES Coronary Guidewire (REF AHW14R317S) is a 0.014" coronary guidewire from Asahi Intecc engineered to combine the smooth tracking of the SION blue family with an extra-support (ES) shaft for enhanced backup and device deliverability during percutaneous coronary intervention (PCI).

Key Features
- 0.014" guidewire designed as a workhorse and support wire for coronary procedures.
- Extra-support (ES) stainless steel core intended to improve pushability, torque transmission and backup support versus the standard SION blue.
- Hydrophilic coating on the distal segment to reduce friction and support smooth navigation through tortuous anatomy.
- ACT ONE technology core-to-tip construction for 1:1 torque response and tip durability.
- Soft, shapeable tip designed for atraumatic vessel and lesion navigation.
- Overall wire length and tip load: Not specified in the located sources for this specific REF; refer to the official Asahi Intecc IFU and product matrix.

Clinical Applications
- Routine wiring of native coronary arteries during diagnostic and interventional PCI.
- Crossing of tortuous and moderately calcified coronary segments where additional shaft support is desired.
- Facilitation of balloon, microcatheter and stent delivery in cases requiring stronger backup than a standard workhorse wire.
- Use as a workhorse or support wire in complex PCI, including bifurcation and chronic total occlusion (CTO) strategies, at the operator's discretion.
