Various types of guide wire production customization - CATALOG springs

The guidewire is the core tool of percutaneous puncture intubation, which mainly provides guidance and support for the catheter, helping the catheter smoothly enter the blood vessel and other cavities and reach the lesion site. It is composed of two parts, inner and outer, and the outer layer is a spring wound with high-quality stainless steel wire, which needs to meet the strict requirements of smoothness, toughness, good elasticity, and bending resistance.

With industry-leading design capabilities and efficient sample trial production delivery time, CATALOG Spring has reached cooperation with a number of benchmark enterprises in the medical industry, and can professionally customize various medical guidewires to meet the needs of diversified clinical interventional operations.

Pain Point Analysis & Solutions for Medical Guidewires

Challenge	CATALOG’s Response	Outcome
1. Poor Fatigue Resistance & Risk of Fracture Inferior core wire material or imprecise coil winding in traditional guidewires leads to low-cycle fatigue failure when subjected to repeated bending during complex navigation, risking intraluminal device fracture and embolization.	Engineered for Durability • Premium Core Wire: Utilizes high-quality, high-tensile stainless steel for optimal smoothness, toughness, and elastic recovery. • Precision Coiling Process: Employs tight process controls to ensure uniform pitch, consistent coil tightness, and perfect core-to-coil bonding, eliminating weak points.	• Enhanced Procedural Reliability: The guidewire exhibits superior resistance to repeated bending and kinking, virtually eliminating the risk of in-procedure fracture and ensuring dependable performance.
2. High Risk of Vessel Wall Trauma During Cannulation A rigid or poorly designed distal tip can perforate, dissect, or cause significant trauma to delicate vessel walls, especially at tortuous anatomical sites, leading to complications like hematoma, pseudoaneurysm, or vessel occlusion.	Safety-First Tip Design • J-Tip Safety Guidewires: Feature a pre-formed, atraumatic J-shaped tip that deflects off vessel walls instead of making perpendicular contact. • Variable Stiffness Straight Wires: Incorporate a 3-20cm distal soft segment (floppy tip) on straight wires to reduce pushing force and hard friction against vessel walls.	• Improved Cannulation Safety: Significantly reduces the risk of vessel wall perforation and trauma, enabling safer navigation through tortuous anatomy and reducing procedural complications.
3. Limited Adaptability to Diverse Anatomical Scenarios The varied anatomy (vascular, biliary, etc.) and access directions require different guidewire properties. A limited product portfolio forces clinical compromise, increasing procedure difficulty and time.	Comprehensive Procedural Portfolio • Full Spectrum of Designs: Offers multi-strand core, melt-core, straight, and J-tip guidewires to match specific procedural requirements (stiffness, torque control, trackability). • Customized Configurations: Provides J-tip wires with multiple bend radii and straight wires with selectable soft segment lengths for precise anatomical matching.	• Unmatched Procedural Versatility: The comprehensive portfolio fully covers a wide range of percutaneous access and cannulation scenarios, allowing clinicians to select the optimal tool for each specific anatomical challenge, improving efficiency and success rates.

Melt-Core Guidewire (High Trackability & Stiffness)

This design features a tapered, high-strength steel core wire integrated within the spring coil at the distal end. The tip is welded and polished to a smooth, atraumatic finish. Its simple construction provides exceptional pushability and guidance stability, making it ideal for navigating through tortuous anatomy where precise control and resistance to kinking are critical.

J-Tip Safety Guidewire (Atraumatic Navigation)

The distal tip is pre-formed into a J-shape, designed to deflect off vessel walls and minimize the risk of perforation or dissection during cannulation. Available in Large, Medium, and Small bend radii to match different vessel and luminal anatomies. Customizable with fixed-core, movable-core, and PTFE (Teflon®) sheath options for enhanced steerability and direction control.

Multi-Strand Guidewire (Enhanced Torque Response & Flexibility)

Constructed from two or more metal wires, arranged either in parallel or wound evenly around a central axis. This configuration provides a unique balance of flexibility, torque transmission, and kink resistance, engineered to meet specific procedural demands for controlled rotation and navigation in complex pathways.

Straight Guidewire (Versatile Standard for Percutaneous Access)

The universal choice for most procedures. Features a 3–5cm distal soft segment (extendable to 15–20cm for specialized needs) to reduce vessel trauma. Offered in fixed-core, movable-core, and PTFE sheath variants. This versatile design provides reliable performance for a wide range of percutaneous puncture and cannulation operations, balancing safety and procedural efficiency.
