Extra-Rigid PTFE Coiled Stainless Guidewire for Peripheral Vascular, Urology & Multi-Disciplinary Interventional Device Exchange

Product Overview

Developed as high-load secondary support wire rather than initial access wire, Amplatz Super Stiff fills clinical demand for stable counter-traction and heavy instrument delivery where standard stainless PTFE guidewires lack sufficient shaft stiffness. The flat outer coil expands inner core cross-section without sacrificing distal coil flexibility, straightens severely tortuous iliac/femoral arteries and ureteral tracts to smooth catheter exchange. Uniform full-length PTFE dry coating maintains low friction during repeated back-and-forth device replacement, no risk of hydrophilic coating shedding. Pre-formed fixed Bentson, straight and 3mm J radiopaque tips avoid manual reshaping damage, delivering consistent fluoroscopic visibility. Strictly contraindicated for thin-walled coronary, cerebral microvessels; not recommended as primary entry navigation wire for routine diagnostic angiography.

Key Highlights

• Max-Rigidity Flat Coil & Enlarged Solid Stainless Core Design: Expanded inner mandrel cross-section provides industry-leading counter-traction performance for large sheaths and endovascular graft delivery.
• Full Dry Integrated PTFE Anti-Friction Jacket: No saline pre-wetting required, sustained low friction during frequent catheter exchange without coating delamination.
• Multi Fixed Non-Reshapeable Radiopaque Tip Portfolio: 6cm/7cm Bentson, short straight, 3mm J factory preset coils eliminate tip breakage from manual bending.
• Dual Safety Balance: Ultra-Stiff Shaft + Soft Distal Platinum Coil: High whole-wire support while lowering perforation risk inside thick ureteral and peripheral arterial walls.
• Multi-Discipline Universal Compatibility: Unified diameter & length system fits peripheral EVAR, percutaneous nephrolithotomy, ureteroscopy and biliary intervention without wire switching.

Technical Specifications & Construction

Fixed factory pre-shaped tip only (manual reshaping prohibited); flat stainless outer coil + monolithic solid 304V stainless inner mandrel; continuous platinum alloy radiopaque distal coil; full shaft seamless PTFE dry coating without hydrophilic polymer overlay. Multiple industrial diameters and multi-length options matching vascular, urinary and biliary interventional scenarios.

Typical Clinical Applications

High-rigidity secondary exchange guidewire exclusively for peripheral vascular surgeons, urologists and interventional gastroenterologists, covering three core interventional systems:

Peripheral Vascular Intervention

• EVAR/TEVAR Endovascular Graft Large Sheath Exchange & Contralateral Vessel Counter-Traction
• Long Iliac/Femoral/Tibial Artery Dilator & Large Stent Stable Delivery

Urological Intervention

• Percutaneous Nephrolithiasis Percutaneous Tract Dilation & Large Access Sheath Placement
• Ureteroscopy Ureteral Stent & Balloon Dilatation Catheter Exchange

Biliary & Gastrointestinal Intervention

• Percutaneous Transhepatic Cholangiography (PTCD) Dilation & Stent Delivery
• Endoscopic Retrograde Biliary Heavy Instrument Counter-Traction Support

Quality Assurance & Compliance

All Amplatz Super Stiff guidewires are manufactured in Class 1000 medical clean workshops under full ISO13485 and FDA peripheral interventional device standards. Distinct from general thin stainless guidewires, each batch undergoes exclusive high-load cyclic anti-buckling fatigue test and PTFE coating adhesion friction cycle inspection. Complete stainless core, flat coil and platinum tip raw material batch archives are permanently stored to support NMPA Class II and global overseas medical registration; every single wire passes shaft rigidity consistency and full fluoroscopic radiopacity inspection before packaging.
