The Asahi Chikai Guidewire (REF WAIN-CKI-200) is a 0.014 in diameter, 200 cm long straight-tip neurovascular guidewire designed to support access, navigation, and microcatheter or device exchange in complex cerebrovascular procedures. Its composite core and hydrophilic coating are engineered to balance shapeability, torque response, and tip durability during selective catheterization of intracranial vessels.
Key Features
Diameter: 0.014 in (0.36 mm)
Working length: 200 cm, suitable for exchange-length applications
Tip configuration: straight, user-shapeable
Hydrophilic coating on the distal segment to support trackability in tortuous anatomy
Composite core construction intended to provide 1:1 torque transmission and tip shape retention
Radiopaque distal segment to aid fluoroscopic visualization
Clinical Applications
Access and navigation of intracranial and distal cerebrovascular vessels
Facilitation of microcatheter delivery and exchange during neurointerventional procedures
Support for diagnostic and interventional workflows in tortuous anatomy where enhanced torque response and tip shapeability are desired
Intended use, indications, and contraindications are as stated in the manufacturer's Instructions for Use
