PTFE Guidewire

Lunderquist Extra-Stiff adopts exclusive gradual tapered solid 304 stainless mandrel with segmented 24K gold radiopaque coil, delivering calibrated medium-high shaft stiffness optimized for aortic EVAR/TEVAR rather than ultra-rigid urinary tract support. Full seamless dry PTFE anti-friction outer jacket eliminates pre-saline activation; 4cm/7cm flexible gold-tipped distal segment balances vessel safety and sustained counter-traction during large stent-graft and long sheath exchange in tortuous aortic vasculature.

Amplatz Super Stiff adopts enlarged solid stainless inner core paired with flat-wound outer coil architecture to deliver unmatched whole-shaft rigidity, dedicated as secondary support exchange wire for heavy sheath, large stent and dilator advancement across thick-walled luminal systems. Full integrated dry PTFE friction-reducing coating eliminates pre-hydration demand; multiple factory preset non-reshapeable atraumatic tip profiles balance supreme shaft stability and distal vessel safety for urologic, peripheral vascular and biliary interventional workflows.

This single-piece solid 304V stainless steel guidewire adopts integral uniform PTFE anti-friction coating, delivering stable high push force and clear direct torque feedback without lubricant activation required. It serves as cost-effective universal access wire for both urinary tract endoscopy and peripheral artery PTA procedures, supporting stable delivery of catheters, stents and dilation balloons across thick-walled luminal tissues.
