Salt medicals extrusion expertise

Minimally invasive devices

Salt Medical specialises in precision extrusions for medical devices, producing high-quality catheter extrusions, multi-lumen tubing, and custom profiles for minimally invasive applications. Using advanced materials and processes, we deliver durable, flexible, biocompatible components that drive innovation and improve patient outcomes.

Our extrusion capabilities

At Salt Medical, we specialize in precision thermoplastic extrusion to support the most demanding medical device applications. Our advanced extrusion processes enable the creation of complex tubing designs with exceptional dimensional control and consistency.

We work with a wide range of medical-grade materials—including PEEK, Pebax®, polyurethane, nylon, and polycarbonate—to produce tubing with inner diameters as small as 0.2 mm and outer diameters up to 20 mm, maintaining tight tolerances down to ±0.0065 mm.

Our capabilities include single- and multi-lumen extrusion, co-extrusion, multi-layer tubing, bump and taper profiles, balloon tubing, and braided or coil-reinforced shafts. We also offer advanced striping options for x-ray visibility and component identification.

All extrusion operations are performed in a controlled cleanroom environment using automated production systems, ensuring the highest levels of quality, repeatability, and performance for your medical tubing needs.

Salt Medical specializes in custom braided and coiled medical tubing designed to improve torque response, flexibility, and kink resistance in advanced catheter systems. Our reinforced shaft solutions are engineered for performance in steerable, delivery, and diagnostic catheters used in minimally invasive procedures.

Leveraging decades of braiding expertise and automated precision equipment, we produce tailored subassemblies or complete outsourced shaft solutions, including:

Braid-on-coil configurations
Variable pitch coiling
Multi-lumen shaft designs
Stepped and tapered diameters

Tubing can be customized with flat or round stainless-steel wire and polymer monofilaments to meet specific mechanical and flexibility requirements.

Applications: Delivery and guiding catheters, steering mechanisms, high-pressure tubing, kink-resistant sheaths, and stent delivery systems.

Partner with Salt Medical for precision-engineered, reinforced catheter tubing designed for next-generation minimally invasive devices.

Our Tri-Layer Tubing combines three distinct material layers into a single-lumen extrusion to deliver tailored performance for high-pressure and high-precision medical applications. By combining materials like Pebax®, polyamide, polyurethane, EFEP, or custom blends, we achieve enhanced lubricity, tensile strength, and elongation control in one integrated structure.

Features include:

Lubricious inner and outer surfaces
Improved burst and tensile strength
Bonding of otherwise incompatible materials using specialized tie layers
Encapsulation of non-medical ingredients for added functionality
Tri-layer bump tubing for variable ID/OD profiles

Available in outer diameters from 0.4 mm to 4 mm with tolerances of ±0.015 mm, every extrusion undergoes in-house testing to ensure consistency and reliability.

Salt Medical’s tri-layer tubing supports performance-critical devices where strength, flexibility, and biocompatibility must coexist

Salt Medical’s micro-extrusion capabilities enable the production of ultra-small, high-precision tubing for implantable and minimally invasive medical devices. Using advanced micro-extrusion platforms, we manufacture both silicone and thermoplastic tubing with unmatched control and repeatability.

Capabilities include:

Inner diameters as small as 0.18 mm (0.007″)
Wall thickness down to 0.05 mm (0.002″)
Multi-lumen and co-extrusion options
Striping for x-ray visibility or part identification

Our cleanroom extrusion environment and automated in-line inspection systems guarantee precision and consistency across every production run.

Applications: Implantable devices, drainage catheters, micro-delivery systems, and other next-generation minimally invasive technologies.

Reliable Tubing for Vascular and High-Pressure Applications

Salt Medical offers high-pressure medical tubing engineered to safely deliver contrast media and fluids under demanding conditions. Our polyurethane tubing, reinforced with polymer monofilaments, maintains constant working pressures of 1200 psi and burst pressures exceeding 1800 psi while retaining flexibility and clarity.

Key Features:

Sterilizable via ETO
Available on spools, cut lengths, or finished assemblies
Customizable dimensions for specific applications

Applications: Vascular delivery systems, high-pressure diagnostic catheters, and infusion devices requiring consistent performance under pressure.

Salt Medical manufactures PEEK tubing for applications demanding high-pressure resistance, chemical stability, and purity. Often used as a lightweight alternative to stainless steel, our PEEK tubing withstands high temperatures, radiation, and harsh chemical environments.

Capabilities:

Variable wall thicknesses, multi-layer construction, and stainless steel reinforcement
Available in coils, spools, or straight lengths
Finished assemblies with connectors for turnkey solutions

Applications: Biopharma fluid handling, high-pressure delivery systems, trace analysis of complex fluids, and sterilizable medical tubing.

Salt Medical offers peristaltic pump tubing in high-purity silicone and biocompatible TPE for reliable fluid transfer in pharmaceutical processes. Manufactured in certified cleanrooms, our tubing meets USP Class VI standards and rigorous extractables testing.

Key Benefits:

Exceptional strength and volumetric consistency
Extended wear for high-cycle pump applications
Available in standard sizes or custom specifications

Applications: Biopharma fluid handling, single-use systems, and sterile drug delivery operations.

Our ASTC UV-Shield Tubing safeguards photosensitive drugs and light-sensitive fluids with an opaque outer layer that prevents UV and visible light penetration. Part of the PharmaFocus® Premium line, this silicone extrusion is tailored for precise ID/OD and packaging requirements.

Applications: Bioprocessing, drug delivery, IVD systems, dialysis, and parenteral nutrition.

Salt Medical’s HelixMark® Color Stripe Silicone Tubing offers a reliable method to visually differentiate tubing lines by application, size, or function. With options for red, green, white, or custom striping, our tubing enhances workflow organization and safety.

Applications: Complex fluid management, biopharma production lines, lab systems, and medical device assemblies.
