The Fielder FC Frontline Guide Wire with Hydrophilic Coating

Product Overview

Specially engineered for high-risk delicate coronary micro-anatomy, this ultra-floppy wire serves as first-pass initial wire for tortuous distal branches unsuitable for medium-support routine guidewires. The gradient thin taper core eliminates rigid transition points, naturally fitting narrow, angled micro-vessels and reducing mechanical shear force on fragile endothelium. The 20cm polymer sleeve fully wrapped with proprietary lubricant forms stable aqueous film after repeated lesion crossing, avoiding rapid coating shedding. A 3cm integrated platinum-nickel radiopaque coil at the terminal spring segment enables precise micro-lesion positioning under low-dose fluoroscopy. Limited 0.8gf contact load drastically cuts dissection and perforation probability for elderly patients with thin coronary walls. This device is strictly not indicated for heavy calcified full chronic total occlusion crossing and all cerebral neurovascular interventional operations.

Key Highlights

• Gradient Taper Monolithic Elastic Nitinol Core: Progressive thinning design delivers ultra-low shaft stiffness to adapt extreme distal vessel bends without kinking.
• 20cm Polymer Base Long-Durability Lubrication Sleeve: Lubricant tightly bonded on polymer substrate retains smoothness during serial micro-branch tracking.
• Standardized 0.8gf Minimal Soft Tip Load: Ultra-light contact force minimizes trauma to thin, fragile coronary intima of aged patients.
• 11cm Flexible Transition Spring with 3cm Continuous Radiopaque Coil: Extended flexible segment plus long marker zone realizes full visualization of tiny distal lesion segments.
• Atraumatic First-Pass Navigation Performance: Optimized soft tip geometry improves success rate of initial access to inaccessible tortuous micro-branches.

Technical Specifications & Construction

Two factory tip options: manually reshaping straight tip / factory pre-formed mild J tip; distal 20cm polymer lubrication sleeve, proximal shaft covered wear-resistant PTFE anti-friction jacket; 11cm flexible spring transition section with 3cm fixed platinum-nickel radiopaque coil at the terminal.

Typical Clinical Applications

Specialized ultra-low-trauma micro-vessel navigation wire for PCI cases with high vessel safety thresholds, limited to five delicate coronary scenarios:

• Long-Distance Tracking & Micro-Stent Delivery for Severely Tortuous Distal Tiny Side Branches
• Minimally Invasive PCI Treatment for Geriatric Patients with Thin Fragile Coronary Endothelium
• Atraumatic True Lumen Crossing for Coronary Sub-Total Occlusive Lesions
• Micro-Branch Access Inside Complex True Bifurcation Lesions
• Serial Short Micro-Stenosis Long-Tracking of Multi-Vessel Distal Coronary Segments

Quality Assurance & Compliance

All ultra-floppy micro-vessel guidewires are manufactured in Class 100 ultra-clean production facilities under full ISO13485 quality management control. Each batch undergoes exclusive ultra-low tip load biocompatibility simulation and thin-vessel cyclic torsion fatigue testing independent from medium-support guidewire inspection standards. Complete raw material trace archives of nitinol core, polymer lubrication sleeve and platinum coil are permanently stored; every finished wire passes one-by-one inspection of coating adhesion and tip softness before packaging, supporting multi-region medical device registration submissions.
