FAQs: Catheter Components for Medical Applications

Catheter components are small but intricately designed parts that allow the delivery of fluids, the draining of fluids, and the entrance of devices for diagnostic purposes into the body through blood vessels and cavities in a minimally invasive manner. These components include catheter hubs which provide luer connections and fluid access ports, needle introducers for vascular access of 14–24 gauge needles, guide wires, which help in navigating vessels, assemblies that connect catheter segments, manifolds that allow the distribution of contrast agents and medications for multiple lumens, dilators that help in catheter insertion, hemostasis valves that prevent blood backflow, and reinforcement components braided or coil-reinforced, that provide resistance against kinking.

Medical grade stainless steel like 304, 316L, and 17-4 PH is used for crafting medical devices owing to its remarkable compatibility with blood and its corrosion resistance to bodily fluids along with its sterilization. It is also strong enough to use for thin-walled components and make electropolished surfaces with finishes below 0.05 Ra microns which minimizes thrombogenicity. Titanium shows unparalleled compatibility, corrosion resistance, and radiopacity for dual use with fluoroscopy. Additionally, it is MRI compatible which means it can be used for long term implants. Brass is cost effective, can be used for sophisticated machining of hubs and connectors as well as for non-blood contact applications. Medical grade polymers PEEK and polycarbonate are also used to make catheters due to their lightweight, flexible, autoclavable, and transparent construction as well as fluid visualization.

Swiss CNC turning machines are used to make catheter hubs, connectors, and introducers made of plastic or metal which can be 1-12 mm in diameter and as thin as 0.2 mm in wall thickness. Passages for lumens and side holes are created with micro-drilling techniques where diameters can be 0.3-3 mm. Flat and thin walled tubes are laser cut using focused light to create intricate slot patterns and fenestrations. Precision machines will polish, turn, and taper any parts to create smooth transitions. Electro-polishing techniques are used to reduce friction on blood contact surfaces to reduce up to 0.05 Ra microns which minimizes the risk of thrombosis. Miniature luer threads as well as the 594 ISO standards can be made using thread grinding techniques.

We achieve outer diameter tolerances to ±0.0003 inches for precise insertion through vessels and introducers, lumen diameter tolerances to ±0.0005 inches for predictable fluid flow, wall thickness tolerances to ±0.0002 inches for no weak points, concentricality to ±0.0003 inches for smooth insertion and tracking, and electropolished surfaces with tissue trauma minimised under 0.05 Ra microns. Additionally, we achieve taper luer dimensions to ±0.0003 inches per ISO 594 standards for luer connections to be leak proof and secure.

Yes, we provide rapid prototyping to verify fit and test assembly, with same-day CAD-to-part capability available for critical projects. For custom automation cells and research platforms, we perform low-volume production of 20 to 500 brackets. For standardized robot models, we perform high-volume production of thousands to tens of thousands of brackets annually, incorporating complete dimensional inspection, flatness verification, and material certifications.

All components are taken under the standards of ISO 13485 and complete integration of FDA criteria for Class II and Class III medical devices, MDR of Europe, ISO 594 standards for luer connectors, and ISO 10993 including hemocompatibility and cytotoxicity standards for materials, biocompatibility, and traceability from materials to the finished product, along with GP for the safety of the patients during vascular access and fluid delivery procedures.

We provide comprehensive finishing solutions tailored to aerospace requirements:
Anodizing (Type II and Type III)
Passivation for corrosion resistance
Precision polishing for aerodynamic surfaces
Custom protective coatings and thermal barriers

For standard catheter hubs and connectors it is between 10 and 15 workdays. This covers Swiss turning, electropolishing, and quality checking. For more complex miniature assemblies with integrated parts, it is about 4 to 5 weeks. Depending on the availability of materials and the requirements of micro-machining, prototype runs for clinical evaluations can take 7 to 10 days.

Of course. We engineer small-sized parts for pediatric and neonatal catheters with outer diameters under 2 French (0.67 millimeters). We also design components for angiography high-pressure injection assemblies that can endure 1200 psi, multi-lumen hubs that can split and control 2 to 7 different streams of fluid, and radiopaque parts that can be seen under fluoroscopy and provide better mapped control. Flexible parts that can navigate through tortuous vessels and long central lines made of antimicrobial material to prevent infection. We also integrate assemblies of hubs, valves, and extension sets that can be used and distributed in a sterile pack.

Controlled outer diameters to ±0.0003 inches allows atraumatic insertion to vessels and introducers reducing the insertion force and minimizing vessel trauma. Predictable flow rates for contrast injections and medication delivery are sustained due to accurate lumen dimensions to ±0.0005 inches. Weak points that may cause catheter fracture or separation during procedures are prevented by uniform wall thickness to ±0.0002 inches. Electropolished surfaces below 0.05 Ra microns are ultra-smooth and friction reducing during advancement through tortuous anatomy and also reduce the thrombogenicity of the catheter by 30 to 50 percent. Concentricity to 0.0003 inches preserves catheter tracking to guide wires and prevents vessel perforation. Safe dwell times of hours to weeks based on type and application of catheter are made possible by biocompatible and surface treated materials to prevent adverse reactions.
