MeKo's Manufacturing Processes

Laser Cutting
Our laser machines enable cutting and drilling with a precision of up to ±2 µm.
- Highest cutting quality with lowest heat impact to the material.
- Nearly no limitations in cutting length and tube diameter.
- Cutting stents in the expanded shape (thin wall tubing with large diameters).
- Extremely precise measuring techniques.
- Proprietary cleaning processes.

Shape Setting
Most demanding geometries are realized with our advanced shape setting tools.
- Accurately controlled heating cycles ensure reliable transformation temperature (Af) settings and precise shape settings.
- Af temperature testing with differential scanning calorimetry (DSC), tensile and radial force resistance measurements.
- Bend and free recovery (BFR) test is a non-destructive, computer-assisted way to accurately measure the active Af temperature of sensitive geometries.

Electropolishing
Homogeneous and constant material removal through our optimized electropolishing processes.
- Widely adjustable range of material removal.
- No contact marks.
- Round strut edges on the inner and the outer side of the device.

Passivation
Surface passivation enhances biocompatibility. Results meet and exceed the corrosion resistance requirements of ASTM 2129.

Marker Crimping
Radiopaque markers enable X-ray visibility of the devices. We offer highly precise pressing and welding for materials like Ta, Au, Pt, Pt-Ir.

Superior Inspection
100 % visual inspection ensures perfect quality. We offer manual and automated dimensional and topography inspections with stereo and telecentric microscopes, scanning electron microscopes (SEM), CLSM etc.

NiTi - the ideal alloy for medical devices
Nickel titanium (NiTi - also known as Nitinol) is an ideal alloy for many medical components due to its superelasticity, shape memory, strength and corrosion resistance.

Questions and Answers
How important is controlling laser kerf width prior to processing?
It is directly influencing the dimensional accuracy. Controlling it and assuring consistency is essential.
What is the minimum edge fillet achievable with laser cutting?
Does MeKo remove oxide layer from shape set prior to electropolishing?
Has MeKo ever seen issues with unpolished regions after Electropolishing? What could cause this?
Does MeKo primarily shape set tube or as well flat sheet?
Does MeKo have any tips for simplifying fixturing for shape set fixtures that have multiple parts?
How does MeKo prepare stent samples for DSC measurement?
What information about the shape setting does MeKo share with customers?
How high is the lowest Strut thickness MeKo can produce?
What is MeKo's strut to strut, strut width delta tolerance (i.e. thick-thin neighboring struts) for a diamond cell stent, heart valve, etc.?
How has MeKo seen incoming material variation affect the laser cutting, shape setting and Electropolishing processes?
Does MeKo have internal capability for metallographic analysis of parts? Are you able to section parts and view the heat affected zones?
How strongly does MeKo weigh the importance of geometry optimization in contrast to material optimization in stent development?
If the shape-setting is done at around 400°C-600°C, does this affect the implant by possible post-processes that require high pressure (around 90-100 atm) and temperatures around 100-200 °C? Or does the pressure have no effect on the material properties as long as the temperature is relatively low?
