Vision™ Zebra Guidewires for Urinary Tract

The Vision™ urological zebra guidewire is a single-use, sterile endourological guidewire designed to give urologists real-time visual control and confident wire management throughout the full range of upper and lower urinary tract procedures. Its signature blue-and-white PTFE striped jacket—the defining feature of every zebra guidewire urology product—functions as a continuous position marker under both endoscopic and fluoroscopic imaging, allowing the surgeon to track wire advancement, rotation, and depth at a glance, without additional radiation exposure.

Built on a kink-resistant nitinol core with a tungsten-containing radiopaque distal tip, and available in both hydrophilic tip and PTFE tip configurations, the Vision™ is manufactured by Hainwise Medical Technology Co., Ltd.—a Shenzhen-based interventional device specialist with over a decade of in-house guidewire manufacturing expertise, supplying urological zebra guidewires to distribution partners across Europe, Southeast Asia, the Middle East, and Latin America under OEM and private label programs.

(Note: Additional sizes and custom lengths available upon request for OEM/ODM projects.)

● Striped (Zebra) Pattern: Distinct visual marker that enhances recognition of guidewire movement under fluoroscopy, potentially reducing radiation exposure by minimizing repeated imaging.

● Reliable Tracking: The unique striping supports consistent orientation checks, particularly during device exchange or repositioning.

● Tip Options:

    - Hydrophilic Tip: Features a soft, atraumatic tip with a lubricious coating that minimizes friction within the ureter or urinary tract, enabling smooth navigation and reducing the risk of tissue trauma.

    - PTFE Tip: Incorporates a zebra pattern for enhanced visual monitoring of wire manipulation. The durable finish supports repeated passage through tortuous pathways while maintaining structural integrity.

● Robust Core Construction: A sturdy core provides kink resistance and efficient torque transmission, facilitating navigation through acute angles and complex anatomies.

● High Maneuverability: Ensures stable positioning within the renal collecting system or distal ureter, delivering reliable support for device placement.

These design characteristics make the disposable zebra guidewire particularly suitable for negotiating tight ureteral strictures and tortuous urinary tract anatomy while maintaining excellent control and safety.

Main performance benefits

The Vision™ Zebra guidewire for urinary tract is engineered to deliver smooth, reliable and controlled access during urology procedures.

Main performance benefits:

● Excellent torqueability and pushability, allowing precise navigation and positioning in the urinary tract.

● Kink‑resistant nitinol core maintains shape and support during complex manoeuvres.

● Low‑friction PTFE jacket minimizes resistance, reducing the risk of mucosal trauma and facilitating catheter and stent passage.

● Enhanced visualization thanks to the blue‑and‑white zebra stripes and radiopaque tip, giving the urologist better feedback under endoscopic and fluoroscopic imaging.

● Single‑use, sterile, EO sterilized design reducing infection risk and ensuring consistent performance.

The Vision™ Zebra guidewire is intended for use as a guide for the introduction and placement of urological devices within the urinary tract.

1. Suitable for Multiple Urological Procedures

● Applicable to ureteral stricture dilation, cystoscopy, ureteroscopic stone removal, stent placement, dilation and nephrostomy procedures,and other complex urinary interventions.

● Provides stable guidance for procedures requiring higher support, such as percutaneous nephrolithotomy (PCNL), ensuring smooth device advancement.

2. Minimizes Re-Interventions and Tissue Injury

● Designed to reduce mucosal irritation and trauma from repeated manipulation, helping minimize intraoperative tissue injury and bleeding.

● The zebra-striped pattern enhances fluoroscopic visibility, reducing repeated imaging and radiation exposure for patients and staff.

By providing secure and atraumatic access, this guidewire for urinary tract helps clinicians place catheters, stents and other urological devices safely and efficiently.

HydrophilicType

● Ultra-smooth soft tip ensures excellent passability

● Hydrophilic coating reduces friction during navigation

Hydrophobic Type

● Seamless one-piece construction eliminates tip detachment risk

● Enhanced tip flexibility improves trackability

Vision™ Zebra vs. Lubric™ Hydrophilic — Choosing the Right Urological Guidewire

Hainwise offers two urological guidewire product lines for the urinary tract. Here is how to select the appropriate wire for your clinical context:

Hainwise Medical operates a fully vertically integrated urological zebra guidewire manufacturing facility in Shenzhen, China, covering all critical production processes in-house:

• Nitinol core wire drawing and annealing

• PTFE stripe jacket extrusion and color patterning

• Hydrophilic coating application and curing (validated by adhesion and lubricity testing)

• Tungsten radiopaque tip attachment and crimp bonding

• Tip forming (straight, angled, J-tip) and dimensional verification

• EO sterilization validation and sterile packaging

OEM service offering includes:

• Custom configurations — diameter, length, tip type, tip shape, stripe color pattern, and core stiffness on request

• Private label packaging — your brand identity, your product codes, your IFU; we handle GMP-compliant production and EO sterilization

• Regulatory documentation — batch records, biocompatibility data, CE technical file support, and NMPA compliance documentation upon request

• Consistent batch traceability — full material-to-finished-goods traceability under ISO 13485-certified QMS

• Scalable production — from evaluation batches to high-volume distribution supply contracts

Frequently Asked Questions

Q: What exactly is a "zebra guidewire" and why is it used instead of a plain guidewire in urology?

A:A zebra guidewire refers to a urological guidewire with an alternating striped outer jacket—typically blue-and-white or yellow-and-black—that serves as a continuous visual position reference under endoscopic and fluoroscopic imaging. Unlike plain single-color guidewires, the stripe pattern allows real-time confirmation of wire advancement, rotation, and position during multi-step urological procedures, reducing radiation exposure and the risk of positional errors during device exchanges.

Q: What is the difference between the hydrophilic tip and PTFE tip variant of the Vision™ Zebra?

A:The hydrophilic tip variant adds a lubricious polymer coating to the distal working segment that activates on contact with fluid, making it ideal for crossing tight ureteral strictures or impacted stone columns. The PTFE tip variant maintains the full-length striped pattern to the wire tip, providing better tactile feedback and is preferred for routine access procedures and high-volume device exchanges where tip feel is more important than maximum distal lubricity.

Q: Is the tungsten radiopaque tip as visible under fluoroscopy as a platinum tip?

A:Tungsten provides strong radiopacity under standard fluoroscopic imaging used in urology suites. The Vision™ distal tip is validated to deliver reliable fluoroscopic visibility for tip position confirmation during ureteroscopy, PCNL, and nephrostomy procedures.

Q: Can the Vision™ Zebra be used as a safety wire alongside a working wire in ureteroscopy?

A:Yes. One of the most common clinical applications of the urological zebra guidewire is as a safety wire—placed into the renal pelvis prior to ureteroscope advancement, remaining in situ throughout the procedure to guarantee re-access to the collecting system if the ureteroscope must be withdrawn and reinserted. The striped pattern makes it easy to confirm the safety wire has not been inadvertently displaced during scope manipulation.
