We provide fully integrated support from design and prototyping to volume manufacturing, ensuring quality and consistency every step of the way.
Metal Tubing
We supply precision metal tubing in stainless steel, Nitinol, and specialty alloys tailored for minimally invasive surgical applications.
Our capabilities include thin-wall and micro-diameter tubing used in devices such as guide catheters, introducer sheaths, and ablation systems. With tight tolerance control, surface finishing options, and support for custom geometries, we deliver tubing solutions that meet exacting clinical and regulatory standards.
Specialty Needles
Our experienced team manufacture high-precision specialty needles for diagnostic and therapeutic use, supporting applications in biopsy, vascular access, drug delivery, and tissue sampling.
Our capabilities span stylet and cannula design, needle-tip grinding, electropolishing, laser marking, and overmolding. From EUS FNA/FNB biopsy needles to custom configurations for minimally invasive procedures, we deliver consistent, high-quality needle components engineered for performance, safety, and reliability in critical care environments.
Metal Shaft Assemblies
Freudenberg Medical produces precision-engineered metal shaft assemblies used in a wide range of minimally invasive devices, including introducer sheaths, valve replacement and repair systems, atherectomy catheters, and stent or drug-coated balloon (DCB) delivery systems.
Our assemblies are designed for deliverability, torque control, and kink resistance and are manufactured using advanced techniques such as laser cutting, centerless grinding, and electropolishing to meet the demanding performance requirements of cardiovascular, neurovascular, and structural heart devices.
Pull Wires
Our high-performance pull wires enable precise deflection and steering in minimally invasive devices such as electrophysiology catheters, steerable sheaths, and structural heart delivery systems.
Our pull wires are engineered for optimal tensile strength, flexibility, and fatigue resistance, supporting complex movement within the body. With capabilities including laser welding, coiling, and overmolding, we deliver reliable solutions tailored to the performance demands of next-generation steerable devices.
Steerable Components
We specialize in precision-engineered steerable components that enable controlled navigation in complex anatomical pathways. These components are integral to a wide range of minimally invasive devices, including electrophysiology and neurovascular catheters, structural heart delivery systems, and endoscopic platforms.
Our expertise spans laser-cut hypotubes, pull wire integration, and advanced assembly techniques to ensure optimal torque, flexibility, and responsiveness, supporting consistent device performance and physician control during critical procedures.

E-Pro® Hypotubes
An advanced metallurgical hypotube solution offering superior kink resistance over traditional '304 stainless steel', making navigation through tortuous anatomies faster and safer.
In thin-walled tube applications, E-Pro's® high kink resistance allows for larger internal diameters thus delivering reduced deflation times leading to a better catheter device. This superior kink resistant E-Pro® hypotube from Freudenberg Medical makes navigation through tortuous anatomies safer.
E-Pro® Hypotube Technical Data
- Medical grade stainless steel hypotube
- Greater kink resistance without compromising pushability, trackability, torqueability
Enhanced kink resistance enables:
- Increase in inner diameter for better inflation/deflation time
- Thinner walls to maximise trackability
- Greater push and torque forces for better manoeuvrability
- More flexiblity improves ‘feel’ of hypotube
- Improved package set properties
E-Pro® Hypotube Benefits:
- High kink resistance reduces risk of failure
- Reduced inflation/deflation times
- Potential to reduce procedure time, improving patient safety
- Allows physicians to use higher forces to deliver solution
