Medical Hypotubes
A high-performance medical guidewire is far more than just "a thin metal tube." It serves as the core skeleton and functional carrier for many advanced minimally invasive interventional medical devices (such as coronary stent delivery systems, neurointerventional instruments, and catheters). Its performance directly determines the device's pushability, trackability, flexibility, resistance to bending, and ultimately the therapeutic efficacy and safety.

Product Details
Features ：
1. Micron-level dimensional accuracy and consistency (e.g., ±0.001 inches or smaller), with low flow resistance and improved passability.
2. Exceptional mechanical properties are demonstrated by the balance between strength and flexibility, enabling adaptation to complex vascular pathways.
3. Excellent surface treatment quality, with an internal and external surface roughness of Ra < 0.6 μm, significantly reducing transport resistance and thrombosis risk.
4. The precision-controlled laser-cut structure, with its ingenious design, enables "directional bending" and "anti-rotation.".
5. Excellent biocompatibility and corrosion resistance, with materials and PTFE coating meeting medical requirements.
6. Multiple materials available, including 316L stainless steel, 304 stainless steel, and nickel-titanium alloy, with customization options.
Application ：
As the core structure and functional component of minimally invasive interventional medical devices, the hypotube is widely used in the following high-end medical device fields:
1. Cardiovascular intervention field
Coronary intervention instruments: used for manufacturing balloon catheters, coronary stent delivery systems, etc. Their excellent pushing force and anti bending properties ensure that the instruments can stably reach the location of coronary artery lesions in the heart.
Peripheral interventional instruments: As the body of peripheral vascular stent delivery system and PTA balloon catheter, they provide the necessary support strength for treating lesions of larger blood vessels such as iliac artery and femoral artery.
2. Precise infusion and drainage field
Precision infusion catheter: used for the body of central venous catheters and implantable infusion ports, with good biocompatibility to ensure the normal delivery of long-term medication.
Drainage catheter: As the core component of various drainage kits such as bile drainage tubes and nephrostomy tubes, it provides a reliable fluid drainage channel.
3. Structural heart disease and electrophysiology field
Large scale delivery system: used for the sheath and outer tube of transcatheter aortic valve replacement (TAVR) system and left atrial appendage occlusion device delivery system, with strong anti bending ability and dimensional accuracy, it is the key to achieving stable delivery of complex instruments.
Electrophysiological catheter: used as the material of the catheter body for mapping and ablation catheters.
4. Other high-value interventional devices
Biopsy needle: As a needle tube for biopsy, it ensures the acquisition of high-quality tissue samples.
Minimally invasive surgical instruments: applied to various laparoscopic instruments, trocar needles, etc., as functional channels or structural components.
