When you look at a pacemaker, an insulin pump or a minimally-invasive catheter, most of the “magic” is actually happening inside a hair-thin stainless-steel tube. Our ASTM A269 316L micro-capillary tubing (< 2 mm OD, wall down to 0.05 mm) is engineered specifically for the medical industry and is already trusted by tier-1 OEMs worldwide.
Surgical & Endoscopic Instruments • Micro-forceps, biopsy jaws and arthroscopic shavers use our tubes as rigid, steerable shafts that transmit torque and irrigation fluid simultaneously. • Electropolished ID (Ra ≤ 0.2 µm) reduces friction and clot formation.
Implantable Devices • Drug-eluting coronary stents: micro-tubes act as reservoirs that release sirolimus or everolimus at a controlled µg/day rate. • Cochlear implants: ultra-thin tubes protect platinum wires from body fluids for 15+ years.
Drug-Delivery Systems • Insulin patch-pumps: 0.3 mm OD tube withstands 3 bar back-pressure without kinking, ensuring ±2 % dosing accuracy. • Subcutaneous implants (e.g., opioid antagonists) rely on our laser-drilled orifices (±5 µm) for zero-order release kinetics.
Diagnostics & Point-of-Care • Blood-gas cartridges: 0.5 mm OD tubes route 50 µL whole-blood samples past micro-electrodes with zero carry-over. • Lab-on-chip manifolds: tubes are bonded to PMMA or COP chips using laser welding for leak-free microfluidics.
Neuro & Cardiovascular Catheters • Micro-guide catheters (OD 0.8 mm) navigate cerebral arteries; our high-torque braid-reinforced tubing delivers pushability while maintaining 1 : 1 torque response. • RF-ablation irrigation lines deliver 37 °C saline at 30 mL/min to cool tissue without causing coagulation.
Quality & Regulatory • 100 % clean-room manufactured (ISO 13485, FDA registered). • Full material traceability (heat no. → coil → cut length). • Sterile packaging: E-beam or EtO validated to ISO 11137/11135.
