Precision Medical Extrusion Catheter

Product Application As a core accessory for various minimally invasive interventional surgeries and medical equipment, our products are widely applied in urology, gastroenterology, respiratory, cardiovascular and other fields. They can be used as instrument channel tubes, fluid delivery tubes, wire sleeves and more, meeting customized demands for high-end medical devices and interventional consumables. Material Specifications Extrusion materials: TPU, TPE, PE, PP, PA, PEBAX, PVC, PC, PETG, PS, FEP, PVDF, PTFE, PFA, ETFE, PEEK, PPSU, etc. Extruded shapes: single-lumen tubes, dual/multi-lumen tubes, double-row/multi-row tubes, dual/triple-color tubes, double/multi-layer tubes, reduced-diameter tubes, special-shaped tubes, thin-walled tubes, micro-bore tubes, coated tubes, braided reinforced tubes, spiral reinforced tubes and so on. Processing range: outer diameter \boldsymbol{0.3–20\ mm}; wall thickness \boldsymbol{0.05–3.0\ mm}; dimensional tolerance \boldsymbol{\pm0.02–0.10\ mm}; custom colors available. Extended Performance Full-body radiopaque formulation and radiopaque stripe optional. All materials comply with international medical biocompatibility standards. Adopting precision extrusion technology, the tubes feature tight dimensional tolerance, smooth inner lumen and uniform wall thickness. Custom structures including single-lumen, multi-lumen and special profiles are available; size, length, hardness and color can be tailored to requirements.
