The Asahi Fielder XT-A (REF APW14R309S) is a tapered-tip coronary guidewire engineered for use in complex percutaneous coronary intervention, including chronic total occlusion (CTO) crossing strategies. It is part of the Asahi Fielder XT family, which is widely referenced in interventional cardiology workflows for navigating microchannels and tortuous coronary anatomy.

Key Features
Tapered distal tip geometry intended to facilitate entry into microchannels within occlusive lesions.
Polymer-jacketed (sleeved) distal section to support smooth tracking through challenging anatomy.
Hydrophilic coating on the distal segment to reduce friction during advancement.
Composite core construction characteristic of the Asahi Fielder XT family for torque transmission and shape retention.
Standard 0.014" proximal coronary guidewire platform compatible with conventional coronary microcatheters and over-the-wire systems.

Clinical Applications
Antegrade wiring during coronary CTO percutaneous intervention.
Navigation of tortuous or diffusely diseased coronary segments where a tapered, low-tip-load wire is preferred by the operator.
Use as an exchange or workhorse strategy wire within physician-directed CTO algorithms.
Intended for use by trained interventional cardiologists in accordance with the manufacturer's Instructions for Use.
