As a critical component of minimally invasive interventional catheter delivery systems, the quality of a high-performance hypotube directly dictates clinical trackability, pushability, and patient safety. Utilizing premium medical-grade stainless steel (SUS304L / SUS316L) and leveraging state-of-the-art precision drawing and surface treatment technologies, we offer global medical device OEMs customized hypotube solutions that deliver exceptional pushability, outstanding kink resistance, and precise torque transmission.
Advantages
Superior Mechanical Performance: Rigorously validated through tensile strength, kink values, compression, three-point bending, and elasticity testing. Our hypotubes offer exceptional structural consistency and robust tracking performance in tortuous anatomies.
Ultra-High Surface Precision: The tubing is completely free of surface oxides. Outer surface roughness is tightly controlled within Ra 0.2 μm, and inner roughness within Ra 0.6 μm, guaranteeing minimal friction and optimal internal component passability.
Diverse Surface Treatment Options: In addition to ultra-smooth PTFE coatings (6–12 μm) in black, green, blue, and yellow, we offer advanced precision laser texturing and surface sandblasting to maximize bonding strength at assembly junctions or optimize tactile feedback.
Rapid 30-Day Lead Time: Equipped with an agile manufacturing framework, we guarantee a swift 30-day lead time for fully customized dimensions and strict dimensional tailoring.
One-Stop Integrated Solutions: Fully customizable workflows tailored to your specific prints-including raw tube drawing, precision laser cutting, coating, laser marking, core wire welding, Luer adapter overmolding, cleanroom cleaning, and packaging.
Typical Applications
Widely utilized in PTCA/PTA balloon dilatation catheters, stent delivery systems, neurovascular catheters, microcatheters, and various complex minimally invasive interventional devices.
