- Endoscopes, the use of remarkable materials optimizes the properties: Cobalt alloys for stiff endoscopes.
- Surgical instruments: special needles, resection electrodes, trocart.
- Rigid endoscopes: large choice of superalloys for urology, arthroscopy, laparoscopy…
- Flexible endoscopes: tubing for articulation joints
- All other material for tubular components: AISI 304, AISI 316, Monel
- In-house tubing and component production
- A choice of PH grade materials: MP35N, Phynox, 17.7

- End forming, polishing, assemblY
At your service:
- From single components to complex assemblies
- From the design step to serial production
- Eager to develop new processes to meet your technical and ramp-up requirements
- We will work with you to develop your endoscope design: our experience in problem solving is available to meet your specific technical challenges.
- Express prototyping: quick turnaround at the design stage. To quickly test your ideas, our dedicated team will produce your prototypes, with in-house tubing production, CNC component machining, fabrication and assembly.
- Fully integrated tubing production, to control the key parameters, such as surface finish, dimensional accuracy and material for small and larger quantities.
- Choice of materials, because stainless steel is not always the best answer to your requirements for corrosion resistance, strength, magnetism.
- Special alloys designed for thin wall but very stiff tubing.
- Various geometries, optimized for your specific use: multichannel, side hole…
- A variety of fabrication processes: Swiss turning, bending, swaging, flattening, drilling, EDM cutting or machining, punching…
- Surface control: buffing, electropolishing, passivation, coatings…
- A variety of assembling techniques: welding, laser, plasma, TIG, brazing / soldering / glueing / crimping…
Quality assurance at its best: ISO 9001-2015 and ISO 13485-2016.
Stents, cardiac valves, electrodes, orthopedics, filters
- Very smooth ID and OD for optimized electropolishing and subsequent coating
- An extreme selectivity in raw materials for biocompatibility and micro/macro material homogeneity.
- Seamless tube for improved fatigue resistance.
- Optimized grain size to compromise between fatigue resistance and electropolishing performance.
- Full certification for easy customer’s device registration.
Stainless steel and 316 LVM
- Exceeds the standards requirements, notably for inclusions.
- A 316 LVM stock of more than 200 references, immediately available.
Cobalt based alloys with strong mechanical properties
- L605 ®- Alloy 25 ®- Alacrite XSH ® = Co-Cr-W-Ni-Fe. The Tungsten reinforces the radio-opacity.
- MP35N ® = Co-Ni-Cr-Mo, combines high mechanical properties and a good ductility at the annealed state.
- Elgiloy ®- Phynox ® = Co-Cr-Ni-Mo-Fe. Very high Yield point. A long implants history.
Leading products: stents tubing today
Stents and cardiac valves are vascular implants manufactured from a laser cut tube. Technical and quality requirements on the tube are extremely demanding.
The quality of our implant tubing enables us to supply the world’s largest stent producers. Minitubes offers a unique quality, specific to stents, in several alloys such as 316LVM and cobalt alloys.
Stent designers face difficult challenges. At Minitubes, we have succeeded in understanding them in depth, in order to offer a tubing quality that meets the highest demands:
- a choice of alloys for both balloon inflatable and self-expendable designs.
- an extreme selectivity in raw materials for biocompatibility and micro/macro material homogeneity.
- seamless tube for improved fatigue resistance.
- new limits in dimensional accuracy on Outer Diameter and Wall Thickness for improved laser cutting and struts dimensions consistency.
- very smooth ID and OD for optimized electropolishing and subsequent coating.
- controlled mechanical properties for controlled physical behavior and minimized recoil.
- optimized grain size to compromise between fatigue resistance and electropolishing performance.
- controlled straightness for accurate laser cutting.
- proven inspection methods (high-end instruments, adequate sampling, statistical analysis…) for reliable characterization and improved yield of customer’s production.
- full certification for easy customer’s device registration.
Our team is available to assist you in your device development and material selection with technical expertise and large inventory of stock items.
