Product Description
The Medline Mini Vascular Access Kit with Introducer Needle and Guidewire is designed to support controlled vascular access and easier catheter placement during venous, radial, and other vascular procedures.
Each kit combines a 10 cm introducer sheath, 0.018 in × 45 cm nitinol-core/tungsten guidewire, and 21G × 2.75 in introducer needle in configurations tailored to different procedural requirements.
Available variants provide a choice of 4 Fr or 5 Fr sheath size, standard or echogenic needle design, and regular, stiff, or extra-stiff guidewire/sheath characteristics.
The system incorporates a kink-resistant dilator and sheath to support smooth procedural flow and is engineered for controlled, atraumatic insertion and placement.

Guidewire / System Stiffness
- Regular: Standard procedural flexibility
- Stiff: Increased support
- Extra Stiff: Highest-support option among the listed variants
Needle Type
- Standard: Conventional introducer configuration
- Echogenic: Designed to improve visualization during ultrasound-guided access
The appropriate configuration should be selected by qualified clinical personnel based on anatomy, procedural requirements, imaging technique, access site, and institutional protocol.
