Medical Devices – New Technologies

With our expertise in wet chemical surface treatment we support our customers to meet the demands of new and innovative technologies of the medical technology sector

Customized Substrate Cleaning

Each surface treatment of medical devices requires a preceding and a subsequent cleaning. According to the surface treatment and cleaning requirements different sequences of cleaning process steps are necessary. The right combination of ultrasonic treatment, quick dump rinse, rinsing with chemicals and temperature adjustment reaches highest cleanliness, even for complicated structured and porous substrates. Different drying technologies complete the cleaning procedure.

The combination of a compact modular platform, automated process control and handling as well as  the compliance of all regulatory medical technology requirements forms high quality production equipment for cleaning of a wide range of medical device cleaning, e.g. stents, surgical and dental instruments.

Contactless from tube to finished cannula

Based on the RENA core competences the in-house development of  innovative technology for production of edge retaining and sharp medical cannulas has been pushed. Highest quality and flexible machining of metal cannulas with electrochemical contactless processing: The developed technology achieves high precision shaping of tube and tip with exceptional design flexibility without any surface contamination. Full scale GMP services effectively support a fast and successful qualification and validation.

Via contactless electrochemical shaping, electro polishing and passivation the geometry of the tube and the tip of medical cannulas is individually feasible, e.g. different bevel cuts, Trocar, Franseen, Lancet.

Stent Manufacturing

Coronary  stents are typically made of implantable grade metals, such as stainless steel, nickel titanium (Nitinol), titanium or cobalt chromium (CoCr) alloys. After laser cutting specific surface treatments need to be applied in order to receive a high-quality biocompatible product with a bright shiny surface which is free of defects and exhibits corrosion resistance.

Surface treatment processes include cleaning, pickling, electropolishing and passivation.

The stent processing technology is currently developed by our dedicated engineering and R&D team.
