Specifications:
The document outlines the specifications for catheter and interventional devices designed for the neurovascular system. The guide wire has an outer diameter of 0.014 inches (0.36 mm) and features a straight tip shape. The total length and polymer sheath length are specified in centimeters.

Guide Wire Design:
The guide wire features a classical core-to-tip design ensuring flexibility and tactile feedback for enhanced maneuverability. It includes a multi-section mandrel design for flexibility, traceability, torsion control, and support, allowing safe passage through lesions or tortuous blood vessels.

Sheath Structures:
Two sheath structures are described: a distal coil sheath and polymer sheath for tactile feedback, and an all-polymer sheath for smoother passage through high-resistance lesions.

Separable Point Design:
The guide wire is composed of a 200 cm wire and an extended wire, totaling 320 cm. This design avoids vascular damage upon contact.

Model Availability:
The guide wire is available in two lengths (320 cm and 200 cm) and four models.

Visibility and Coating:
A 3 cm visible coil enhances visibility during operation. Differential coating designs provide distal hydrophilicity to reduce resistance and proximal hydrophobicity to lower friction.

Torque Response:
The guide wire offers good torque control with a 1:1 torque control ratio, ensuring accurate feedback and synchronous operation.

Additional Information:
The document includes schematic diagrams illustrating the separable point and butt joint of the guide wire.
