HI-TORQUE WHISPER EXTRA SUPPORT (ES) adopts reinforced DURASTEEL parabolic tapered stainless core to deliver upgraded shaft rigidity and superior rail performance, engineered for demanding coronary lesions requiring powerful stent and balloon delivery support beyond WHISPER LS & medium-support variants. Equipped with full 25.6cm continuous Hydrocoat hydrophilic polymer jacket and 1.3g standardized tip load, it maintains atraumatic soft navigation while providing enhanced pushability for medium-to-heavy calcified stenosis and multi-stent long-segment procedures.

Single Use OnlyPositioned as the highest-support tier within the WHISPER stainless core portfolio, WHISPER ES is purpose-built for complex coronary PCI scenarios where medium-support wires lack sufficient mechanical stability for bulky stent systems and long lesion tracking. The reinforced parabolic DURASTEEL taper eliminates rigid core transition points to resist buckling under moderate vessel torsion, while full polymer distal jacket with integrated Hydrocoat lubricant forms long-lasting low-friction film without coating shedding during repeated serial lesion crossing. A continuous 3cm platinum-nickel radiopaque coil delivers full fluoroscopic visualization for long-segment occlusions, balancing 1.3g mild atraumatic tip load and boosted shaft rigidity. This wire is contraindicated for cerebral neurovascular intervention and rotational atherectomy matching, and not recommended for ultra-fragile thin distal micro-branches with minimal plaque burden.
Two factory tip configurations: manually reshaping straight tip & factory pre-formed standard J tip; distal full Hydrocoat hydrophilic polymer cladding, proximal shaft covered wear-resistant PTFE hydrophobic outer jacket; 3cm fixed continuous platinum-nickel radiopaque coil at distal working segment.

High-support specialty PCI guidewire for complex coronary intervention cases requiring enhanced device delivery stability, covering five core high-demand lesion scenarios:
All HI-TORQUE WHISPER EXTRA SUPPORT guidewires are manufactured in FDA & CE certified Class III cardiovascular clean production lines under full ISO13485 QMS supervision. Compared with WHISPER LS & medium-support MS variants, each batch undergoes exclusive high-load shaft cyclic buckling fatigue test and long-term Hydrocoat coating abrasion durability inspection. Complete raw material batch trace archives of DURASTEEL core, hydrophilic coating and platinum coil are permanently stored to support domestic NMPA and global multi-region medical device registration; every finished wire passes single-piece tip load, torque stability and full radiopacity inspection before packaging.
Distributed globally to top-tier tertiary cardiac cath labs focusing on complex calcified PCI, multi-stent bifurcation intervention and partial CTO recanalization, plus professional cardiovascular medical device distributors worldwide. Long-term large-volume B2B bulk orders support customized J-tip forming angles and extended special length development; neutral OEM neutral packaging schemes are available upon formal written application. Contact Abbott cardiovascular dedicated sales team to obtain exclusive high-support wire tiered wholesale pricing and cross-border integrated logistics & regional registration document packages.
WHISPER LS is ultra-floppy low-support for mild tortuous micro-branches (1.0g tip load); WHISPER MS delivers balanced medium rigidity for routine single-vessel PCI; WHISPER ES adopts reinforced thick DURASTEEL core with maximum rail support, 1.3g tip load, exclusively for long calcified lesions, multi-stent delivery and partial CTO crossing that insufficiently supported by LS/MS variants.
Not recommended. Its stainless core provides robust pushability for partial CTO, but lacks specialized high-penetration tip structure to break dense full calcified fibrous caps; clinicians shall select PILOT 150 / PILOT 200 series dedicated CTO crossing guidewires for heavy full occlusive lesions.
Standard factory specifications: 190cm & 300cm; the 300cm extended variant is optimized for uninterrupted full tracking of ultra-long multi-vessel serial stenosis; custom lengths from 180cm to 360cm are supported for long-term bulk B2B procurement orders.
adopts patented transitionless hybrid core combining 10cm distal nitinol segment and high-tensile Durasteel stainless proximal shaft, exclusively developed as 0.018-inch peripheral crossing wire for subintimal tracking and chronic total occlusion recanalization. The 4g low-load flattened shapeable tip paired full-length core-to-tip hydrophilic coating delivers balanced high pushability and soft atraumatic performance without compatibility conflict with large-bore 0.018” peripheral catheters.
