0.014” Multi-Coil Composite Core PTCA Wire with Long Durable Lubrication Coating

Product Overview

SION designed as universal daily workhorse wire for routine cardiac catheterization labs, the balanced mid-support model integrates optimized multi-coil core and proprietary durable lubricant coating to simplify preoperative wire selection. The 0.7gf standardized mild tip load minimizes mechanical impact on normal coronary intima, while multi-layer winding core effectively suppresses shaft kinking under mild vascular torsion and slight vessel bending. A continuous 3cm platinum-nickel radiopaque spring coil is integrated at the distal end to mark lesion boundaries clearly under routine fluoroscopy, without requiring high radiation dose. The 28cm full lubrication segment covers the entire working distal zone, with hydrophobic untreated tip reserved to prevent accidental lubricant overflow into micro side branches. This wire is suitable for routine non-complex PCI only; for severely tortuous micro branches and full chronic total occlusions, ultra-low support micro-channel guidewires are recommended instead.

Key Highlights

• Proprietary Multi-Wound ACT Composite Core Structure: Multi-strand layered winding balances instant torque response and anti-buckling capacity for mild tortuous coronary anatomy.
• 28cm Full-Distal SLIP Durable Lubrication Coating: High-adhesion lubricant film resists peeling after multiple serial stenosis passage, maintaining stable low friction for long-distance tracking.
• Stable 0.7gf Standard Mild Tip Load Design: Uniform soft contact force reduces endothelial tear risk while supporting easy manual secondary shaping.
• 3cm Uninterrupted Platinum-Nickel Radiopaque Spring Coil: Extended continuous marker segment realizes full lesion boundary positioning without fluoroscopic blind spots.
• Balanced Mid-Rigidity Shaft Profile: Optimized overall stiffness provides reliable rail support for drug-eluting stents and semi-compliant balloon delivery.

Technical Specifications & Construction

Two factory tip configurations: manually reshaping straight tip / factory pre-formed gentle J tip; 28cm full SLIP lubrication covers distal shaft, distalmost 1.5mm tip remains hydrophobic uncoated zone; 3cm integrated continuous platinum-nickel radiopaque coil fixed at distal working section.

Typical Clinical Applications

General daily frontline navigation wire for routine cardiac interventional cath labs, limited to mild non-complex coronary PTCA procedures as below:

• Elective Single-Vessel Standard Drug-Eluting Stent Implantation Operations
• Semi-Compliant Balloon Dilatation for Non-Calcified Intermediate Stenosis
• Mildly Tortuous Coronary Vessel & Simple True Bifurcation Lesion Crossing
• Initial Wire Navigation for Routine Diagnostic Coronary Angiography
• Tracking of Short Serial Non-Calcified Coronary Stenosis Segments

Quality Assurance & Compliance

All balanced mid-support coronary guidewires are manufactured in Class 100 ultra-clean production workshops complying with global ISO13485 full quality management standards. Each production batch completes exclusive SLIP coating adhesion stability test, standardized 0.7gf tip load consistency inspection and multi-wound core torsion fatigue cycle testing. Complete raw material batch trace archives of composite core, lubrication coating and platinum coil are permanently stored to support domestic and overseas medical device registration submission. Finished wires are inspected one by one for coating smoothness and radiopacity before packaging.
