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.

Single Use OnlyDeveloped as aortic-first dedicated exchange guidewire under Cook vascular portfolio, Lunderquist features unique 11cm progressive taper mandrel to distribute stress evenly and reduce kink risk under aortic arch torsion. 15/18cm long gold distal coil delivers superior fluoroscopic visibility vs platinum coils under low-dose radiation, specifically designed for crossover aortic access and multi-stage endograft deployment. Dry PTFE coating avoids hydrophilic coating delamination during repeated long-distance catheter back-and-forth movement. Available in straight, single-curved and double-curved factory preformed tips; manual reshaping is not recommended to prevent gold coil fracture. Limited to aorta, iliofemoral large peripheral arteries; strictly contraindicated for thin-walled coronary, cerebral microvessels and routine ureteral tract dilation.
Single unified 0.035 inch outer diameter; 11cm progressive tapered solid 304 stainless steel mandrel; distal 15/18cm continuous 24K gold radiopaque coil with 4cm or 7cm flexible soft tip; full seamless dry PTFE outer jacket without hydrophilic polymer layer; factory fixed straight, single-curve and double-curve tip forms, manual reshaping not advised. Standard lengths:90/145/180/260/300cm. EO single disposable sterilization.

Aorta-specialized medium-high stiffness exchange guidewire for vascular surgeons & interventional radiologists, dedicated to aortic endovascular repair and large peripheral artery interventions:
All Lunderquist Extra-Stiff guidewires are manufactured in Cook Class 1000 sterile production lines, fully compliant with ISO13485, FDA 510 (k) Class II cardiovascular standards and China NMPA imported medical device regulations. Distinct from general peripheral stiff wires, each batch implements exclusive aortic arch cyclic torsion stress test and gold coil bonding durability inspection. Complete stainless mandrel, gold coil and PTFE coating raw material batch archives are permanently retained; every finished wire undergoes single-piece taper rigidity and gold radiopacity inspection before packaging.
Globally supplied to tertiary aortic intervention centers, vascular surgery wards and professional aortic endovascular medical distributors. Long-term large-volume B2B bulk orders support customized ultra-long lengths (up to 360cm) and exclusive custom curved tip molds; neutral OEM unbranded packaging can be arranged via formal written application. Contact Cook professional aortic intervention sales team to acquire tiered bulk wholesale pricing, dedicated cross-border aortic device logistics and multi-region registration certification packages.
Lunderquist adopts gradual tapered mandrel + gold coil, medium-high stiffness designed primarily for aortic EVAR/TEVAR, better low-dose fluoroscopy visibility; Amplatz uses thick flat coil ultra-rigid shaft optimized for heavy urinary tract dilation and large urethral sheath exchange, platinum coil with lower X-ray contrast. Lunderquist is not recommended for percutaneous nephrolith procedures.
Not recommended. Manual bending will crack the thin 24K gold coil and cause coil shedding inside aorta; all required vessel curves shall select factory preformed straight/single/double curved models.
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.
