PTFE Coated Stainless Steel Guidewire for Urology and Peripheral Intervention

Product Overview

Developed as multi-department baseline guidewire covering urology and peripheral vascular interventional departments, solid stainless core creates consistent rigid shaft with outstanding tensile strength for long-distance lumen tracking. The integral PTFE hydrophobic outer layer maintains permanent low-friction surface without coating peeling under repeated back-and-forth instrument exchange, different from water-activated hydrophilic coatings used in coronary micro-wires. Atraumatic rounded platinum radiopaque tip reduces mucosal scratch risk inside ureter, iliac and femoral arteries, with multiple customizable tip radians matching curved urinary and peripheral anatomical structures. This device is not recommended for thin-wall coronary or intracranial microvessels due to constant high shaft rigidity.

Key Highlights

• Integral Full-Shaft PTFE Hydrophobic Anti-Friction Coating: No pre-wetting activation needed, stable gliding performance during repeated instrument exchange without coating shedding.
• Solid Monolithic 304V Stainless Steel Core: High tensile resistance and direct 1:1 torque transmission, delivering powerful pushability for impacted urinary calculi & calcified peripheral plaques.
• Rounded Atraumatic Platinum Radiopaque Tip: Multi-radius customizable curved tip minimizes mucosal laceration in tortuous ureter and long peripheral arteries.
• High Tensile Structural Performance: Pass 30N tensile destructive test, suitable for high-traction stone retrieval and long peripheral stent delivery operations.
• Dual-System Universal Compatibility: Unified specification system fits ureteroscopy, PCNL, femoral & iliac PTA without switching wire models between departments.

Technical Specifications & Construction

Solid single-piece 304V stainless steel core with full-shaft uniform PTFE coating; rounded platinum radiopaque tip with optional straight / 3mm J / 6mm J tip radian; multiple industrial standard diameters and lengths for urology & peripheral dual scenarios.

Typical Clinical Applications

Multi-department baseline universal guidewire for urologists and peripheral vascular surgeons, covering two major clinical systems:

Urological Interventions

• Ureteroscope Access & Ureteral Stent Implantation
• PCNL Percutaneous Nephrolithiasis Tract Establishment & Impacted Stone Retrieval
• Diagnostic Retrograde Pyelography Navigation

Peripheral Vascular Interventions

• Femoral, Popliteal & Iliac Artery Mild Calcified Stenosis PTA
• Long-Segment Peripheral Stent & Dilatation Balloon Stable Delivery

Quality Assurance & Compliance

All PTFE coated stainless universal guidewires are manufactured in Class 1000 medical clean workshops complying with ISO13485 and YY 0450.1 interventional accessory standards. Exclusive tensile strength, PTFE coating adhesion and torsional stability testing are implemented for dual-system urology & peripheral application. Complete stainless steel raw material batch archives and coating process records are permanently stored to support domestic NMPA Class II and overseas medical registration. Each finished wire undergoes one-by-one surface smoothness and radiopacity inspection before packaging.
