The "flexible artery" of precision medicine: Shanghai Wewei Technology's Hypotube technology leads the new era of minimally invasive intervention

In the precision world of minimally invasive interventional medicine, every tiny delivery of instruments is crucial to the success or failure of the surgery. Shanghai Wewei Technology Co., Ltd., with its core technology - high-performance Hypotube, is becoming a key driver of this "subtle details determine the world" transformation. As the core skeleton of the catheter system, Wewei's hypotube has laid a precise and safe "flexible artery" for difficult surgeries such as coronary, nerve, and peripheral vascular interventions with its extraordinary push-pull conductivity, smooth passability, and excellent metal memory performance.

Millimeter grade pipes, capable of carrying the power of thousands of tons: the engineering art of precise structure

The hypotube is not an ordinary metal tube. Wewei Technology adopts advanced laser cutting and ultra precision machining technology to carve complex and regular hollow patterns (such as spirals and grids) on stainless steel or nickel titanium alloy base pipes. This design endows the tube with three core properties while achieving ultimate lightweight: excellent axial pushing force, ensuring that force can be transmitted to the distal end without damage during surgery; Flexible radial curvature enables it to conform to complex and tortuous vascular pathways; Stable resistance to bending and compression, preventing the pipe from twisting and collapsing inside the body. Each hypotube is a miniature engineering artwork that integrates the needs of materials science, mechanics, and medicine.

Traversing complex anatomy to reach therapeutic targets: outstanding performance

During surgery, the WeWei hypotube serves as the "vanguard" for the catheter to reach the lesion. Its outstanding performance directly determines the efficiency and safety of surgery:

• Precise control: Excellent torsional response capability enables every minute of rotation of the doctor's operating handle to be accurately transmitted to the far end, achieving precise positioning of the instrument.
• Smooth Navigation: Optimized flexibility and tapered gradient design enable it to smoothly navigate through physiological and anatomical difficulties such as the aortic arch and intracranial vessels, greatly reducing the risk of vascular injury.
• Stable support: Provides strong backend support for therapeutic instruments such as balloons, stents, and microcatheters, ensuring their stable delivery and precise release, especially when dealing with calcified lesions.

Deep empowerment of materials and processes: customized solutions

Wewei Technology is well versed in the diverse needs of different clinical scenarios. In addition to providing widely used stainless steel hypotubes, nickel titanium alloy hypotubes with super elasticity and shape memory effect have also been developed to meet the high requirements for flexibility in fields such as neural intervention. The company has the full chain production capability from material selection, precision laser cutting, heat treatment to surface polishing and cleaning, and can provide customized solutions for subsea pipes including pipe diameter, wall thickness, hollow patterns, and hardness gradient zones according to the specific design of customer conduit products, collaborating with customers for innovation.

Domestic high-end breakthroughs empower innovation in medical devices

For a long time, the high-end sea tube market has been dominated by international manufacturers. Through continuous research and development and technological breakthroughs, Wewei Technology has achieved independent control over key technologies and processes, and its product performance is comparable to the international first-class level. This not only provides a stable, reliable, and more competitive source of core components for domestic medical device manufacturers, promotes the innovative development of domestic high-end interventional devices, but also brings high-quality "Chinese solutions" to the global medical market.
