Elves Crown™ PTCA Guidewires

Elves Crown™ PTCA Guidewire (Super Smooth) is a 0.014" coronary PTCA guidewire designed for percutaneous transluminal coronary angioplasty (PTCA) and percutaneous coronary intervention (PCI) procedures， this guidewire supports the delivery of balloon catheters and  stents, providing reliable access during coronary and peripheral interventions.

This super smooth PTCA guidewire combines a nitinol core with an ultra‑low friction hydrophilic coating to provide excellent torque control, high trackability and reliable device support for crossing coronary lesions and delivering balloons and stents.

Designed and manufactured by Hainwise Medical Technology Co., Ltd., a Shenzhen-based interventional device specialist with over a decade of dedicated R&D in guidewire engineering, the Elves Crown™ Super Smooth is available with full OEM customization and ISO 13485-certified production traceability.

Understanding what's inside the wire explains why it performs the way it does.

Nitinol Distal Core

The nitinol radiopaque distal core provides kink resistance and shape memory that stainless steel alone cannot match. Where a stainless-steel core may permanently deform in tight bends, the nitinol segment springs back—maintaining tip shape across repeated maneuvers and reducing the risk of wire deformation during complex lesion crossing.

Ultra-Low Friction Hydrophilic Polymer Coating

The hallmark of the Super Smooth variant is its hydrophilic coating—a lubricious polymer layer that becomes slippery on contact with blood and saline, dramatically reducing frictional resistance as the PTCA guidewire tracks through the vessel lumen. This is particularly valuable in:

• Highly tortuous coronary segments (RCA shepherd's crook, circumflex take-offs, LAD diagonal branches)

• Long lesions requiring multiple device exchanges along the same wire

• Resistant stenoses where crossing friction would otherwise compromise wire advancement

The coating extends across the distal working segment, where friction matters most, while the proximal shaft retains tactile feedback.

Optimized Shaft Architecture

The proximal stainless-steel shaft combined with a PTFE outer coating provides the column strength and anti-friction properties needed for consistent push force delivery. The transition from proximal rigidity to distal flexibility is engineered to prevent abrupt stiffness changes that can cause buckling in tight anatomies.

Soft, Shapeable Atraumatic Distal Tip

The distal tip is designed to be manually shapeable—allowing the operator to pre-form a curve prior to insertion—and atraumatic, minimizing the risk of intimal injury or perforation during wire advancement and manipulation.

The PTCA guidewire (Super Smooth) is intended to facilitate the placement of balloon dilatation catheters and other interventional devices during PTCA and PTA procedures.
It is primarily used as a coronary guidewire in PCI procedures to:

● Access and cross stenotic coronary lesions

● Provide a stable rail for coronary balloon catheters and coronary stent delivery systems

● Navigate tortuous coronary vessels and side branches

● Support device delivery in complex stenotic lesions and long lesions

In addition to coronary intervention, the super smooth PTCA guidewire can also be considered for selected peripheral transluminal angioplasty (PTA) procedures where a 0.014" guidewire is required, subject to physician judgment and local regulatory indications.

Elves Crown™ Super Smooth vs. Standard Elves Crown™ — Which Wire Should You Choose?

Hainwise offers two variants of the Elves Crown™ PTCA guidewire family. Here's how to match wire selection to clinical scenario:

● Manufactured under EN ISO 13485 certified quality management system

● Full batch traceability

● Validated manufacturing processes

● Compliance documentation available upon request

Hainwise Medical operates fully integrated, in-house guidewire production lines—from raw nitinol and stainless-steel processing through coating, assembly, tip forming, and sterile packaging—all within our ISO 13485-certified facility in Shenzhen, Guangdong, China.

What our OEM partners receive:

• Custom wire configurations — diameter, working length, tip load, coating length, and tip shape geometry tailored to your product specification

• Private label packaging — your brand, your IFU, your product codes; we handle production and documentation

• Regulatory documentation support — CE technical file assistance, batch-level traceability records, and compliance dossiers upon request

• Consistent batch quality — validated manufacturing processes with full statistical process control (SPC) and batch traceability from raw material to finished goods

• Flexible MOQ — scalable production runs from evaluation batches to high-volume distribution orders

We currently supply hydrophilic PTCA guidewire products to distribution partners in Europe, Southeast Asia, the Middle East, and Latin America under OEM and private label arrangements.

Frequently Asked Questions

Q: What makes a "hydrophilic" PTCA guidewire different from a standard PTFE-coated wire?

A：A standard PTFE-coated wire provides low friction from a dry lubricious polymer. A hydrophilic PTCA guidewire goes further: the hydrophilic coating absorbs water on contact with physiological fluids, becoming significantly more slippery than PTFE alone. This makes it notably easier to advance through tortuous or resistant lesions—at the cost of slightly reduced tactile feedback compared to non-hydrophilic wires.

Q: Is the Elves Crown™ Super Smooth a workhorse wire or a specialty wire?

A：It is positioned as a workhorse-plus wire—suitable for the broad range of routine PCI cases, with enhanced capability in tortuous anatomy and long lesion cases where the hydrophilic coating provides meaningful performance advantage. It is not a CTO (chronic total occlusion) wire; for high tip-load CTO penetration, Hainwise offers dedicated CTO-class guidewires.

Q: Can the distal tip be re-shaped intraoperatively?

A：Yes. The soft distal tip is designed to be manually shapeable before and during the procedure, allowing the operator to adjust the bend angle as the clinical situation requires. The nitinol distal core provides shape retention after tip forming.

Q: What tip load variants are available?

A：The Elves Crown™ Super Smooth is available in multiple tip load configurations. Contact the Hainwise technical team for current availability and to discuss the appropriate tip load for your target clinical indication.

Q: Does Hainwise offer a 300 cm length for wire exchange techniques?

A：Yes. The 300 cm exchange-length PTCA guidewire is available for procedures requiring balloon catheter exchange without losing coronary position. Contact us for availability in this configuration.

Q: What is the minimum order for OEM/private label production?

A：MOQ varies by configuration and labeling complexity. Contact our business development team directly for a customized quotation and sample shipment request.
