Supports next-generation medical devices with unmatched flexibility and efficiency.
At Salt Medical, our engineering team has extensive expertise in developing innovative tubing solutions for next-generation catheter devices.
We design tubing across a range of outer and inner diameters, wall thicknesses, and lengths, with a focus on ultra-thin-walled tubing for advanced medical applications.
Our tubing capabilities include:
Reinforced tubing
Coextruded tubing
Multi-lumen tubing
Micro-extruded tubing
Peel-away tubing
Sheathing
We offer both braid and coil reinforcement technologies in our state-of-the-art facility, supported by deep materials knowledge.
Our engineers develop reinforced tubing tailored to your device’s performance needs, using braid, coil, or hybrid configurations.
Reinforcement options include:
Flat or round coil profiles
Various materials (nitinol, stainless steel, fabric, etc.)
Closed or open coils
Variable pitch coil reinforcement
Smooth tapered transitions
Left- or right-handed coiling
Compression coils
Coil-over-coil or coil-over-braid designs
Welded coil terminations
Performance enhancements:
Kink prevention
Improved crush resistance
Enhanced torque control and transmission
Under-pressure and compression resistance
Extensive material expertise to optimise performance, manufacturability, and compliance with medical standards.
Our engineers select materials based on:
Device performance requirements
Biocompatibility
Sterilisation compatibility
Processing and manufacturing considerations
Chemical resistance and shelf-life stability
Material expertise includes:
Tubing: PEBAX, TPE, EVA, HDPE, LDPE, TPU, polyimide, silicone rubber
Liners: PTFE, polyethylene, FEP, hydrophilic coatings
Reinforcement: Nitinol, stainless steel, PEEK, PET, nylon, aramid

Specialty materials for unique applications:
ePTFE, barium sulphate, polysulfone, cobalt-chromium, silver chloride, gold, PMMA, platinum-iridium, tungsten, hydrogel, nanoparticles, and foam.
Beyond tubing and shafts, we design and integrate a wide range of components and secondary operations, ensuring full catheter system performance and manufacturability.
Capabilities include:
Handle Design
Ergonomic handles for precise control, including push/pull, levered, and rotating wheel steering designs.
Injectors
Expertise in contrast media injectors, syringeless systems, contrast delivery injectors, and power injectors.
Peelable Hubs
Peelable hubs, cannulas, and sheaths engineered for smooth, even removal and easy use.
Y-Connectors
Two-way, four-way, barbed, and luer designs with optimised flow rates, control, and patient comfort.
Tips & Caps
Custom tip geometries (split, shotgun, step tips, etc.) tailored for stability, functionality, and precision.
We provide catheter packaging design that ensures product protection, sterility, and full compliance with EU MDR and FDA regulations.
Our team optimises packaging design for manufacturability, labelling accuracy, and cost-effectiveness by minimising material use and assembly time.
