The ASAHI SION black Coronary Guidewire (REF APW14R010J) is a workhorse-class coronary guidewire engineered by Asahi Intecc for use in percutaneous coronary interventions (PCI). Built on Asahi's ACT ONE core-to-tip technology, the SION black is designed to deliver a balance of tip load, torque transmission and tactile feedback when navigating tortuous or diseased coronary vasculature.

Key Features
Core-to-tip ACT ONE construction for 1:1 torque response and durability.
Hydrophilic polymer coating along the distal segment to reduce friction in tortuous anatomy.
Low-friction tip design intended to support navigation across challenging lesion morphology.
Stainless steel proximal shaft for pushability and support.
Shapeable distal tip to allow operator customization at the table.
Compatible with standard rapid-exchange and over-the-wire PCI workflows.

Clinical Applications
Intended for use as a guidewire to facilitate the placement of interventional devices within the coronary vasculature during diagnostic and therapeutic catheter-based procedures.
Commonly selected in PCI workflows requiring controlled distal access through tortuous segments.
May be considered as a workhorse or secondary wire in complex lesion crossing strategies, including support for microcatheter exchanges. Clinical suitability is at the discretion of the treating physician.
