0.018” Nitinol-Stainless Hybrid Hydrophilic Guidewire for BTK, SFA & Complex Peripheral CTO Subintimal Tracking

Product Overview

As a professional hybrid crossing wire under Abbott Hi-Torque COMMAND 18 series, ST variant differentiates from LT navigation model via short 10cm distal nitinol hybrid structure to prioritize lesion penetration and subintimal loop prolapse capacity, targeting femoropopliteal, tibial BTK complex occlusive lesions. Parabolic grinding transition-free core eliminates torque attenuation during long-distance peripheral manipulation; integrated full polymer hydrophilic cladding maintains stable lubricity through calcified, tortuous long-segment vasculature. 3cm continuous platinum-nickel radiopaque coil ensures complete lesion visualization under low-dose fluoroscopy, while balanced hybrid rigidity avoids excessive shaft stiffness causing arterial wall perforation during hard plaque penetration. This wire is contraindicated for coronary and intracranial vascular procedures, solely designed for peripheral arterial interventional scenarios.

Key Highlights

• 10cm Short Distal Nitinol Hybrid Core (ST Exclusive Spec): Shortened nitinol segment delivers boosted pushability & crossing force for rigid calcified peripheral CTOs, superior to 25cm nitinol LT model in subintimal prolapse efficiency.
• Transitionless Weld Parabolic Core Design: Seamless metal transition realizes 1:1 lossless torque transmission from proximal shaft to flattened tip, no torsion lag during tortuous vessel steering.
• 4g Low-Load Flattened Re-Shapable Nitinol Tip: Cold-formed flat tip retains shape after repeated subintimal looping, minimizes vessel dissection while sustaining stable penetration force.
• Full Core-To-Tip Continuous Hydrophilic Polymer Coating: Entire working segment coated without segmentation friction gaps, durable lubricity for long-segment peripheral lesion tracking.
• 3cm Extended Platinum-Nickel Radiopaque Spring Coil: Long continuous marker zone enables real-time full-length lesion positioning, reducing fluoroscopy radiation exposure for clinicians.

Technical Specifications & Construction

Single flattened manual shapeable tip (no factory J preform option); 10cm distal superelastic nitinol + proximal high tensile Durasteel stainless hybrid core; 3cm uninterrupted platinum-nickel radiopaque coil covers distal working segment for full lesion fluoroscopic tracking.

Typical Clinical Applications

Specialized hybrid crossing guidewire exclusively for peripheral arterial interventional radiologists & vascular surgeons, limited to lower-extremity peripheral PTA/CTO recanalization operations:

• Subintimal Tracking & True Lumen Crossing for Femoropopliteal Long-Segment CTO Lesions
• Calcified BTK Tibial Artery Occlusion Recanalization (Above & Below Knee Interventions)
• Tight Loop Prolapse Operation for Severely Tortuous Peripheral Arterial Lesions
• Large-Bore 0.018” Peripheral Balloon & Stent Stable Delivery Rail
• Initial Crossing Wire for Moderate-Hard Plaque Iliac Artery Stenosis

Quality Assurance & Compliance

All Hi-Torque COMMAND 18 ST guidewires are manufactured on peripheral vascular medical device clean production lines, fully compliant with ISO13485, FDA 510(k) and CE MDR peripheral interventional regulatory standards. Independent hybrid core torsion fatigue, subintimal repeated shaping durability and long-term coating abrasion dedicated tests are added beyond general guidewire inspection standards. Every finished wire undergoes single-piece tip load & radiopacity inspection before packaging.
