Only few new materials have been successfully introduced in the recent decades in orthopaedics and neurosurgery beside austenitic stainless steels or high strength titanium alloys. While new metallic alloys (NiTi, TiMo, TiZr, Ta) have been applied by few companies, polyaryletherketones homopolymers PEEK and PEKK have been selected for many new medical devices for the spine surgery and other cranio-maxillofacial indications, either for brand new products or to replace existing metallic implants (cages, pedicle screws, cranial plates). MRI compatibility and lower stiffness are two advantages of the non-filled polymers that supported the material introduction. More recently implants made of reinforced resin (PEEK) with short or long fibres have been developed and introduced on the market. However for both filled and non-filled materials, a secondary complete osseointegration through bone apposition cannot be achieved, as a thin layer of fibrous tissue is first developed on the material surface. Resulting potential instability of the implant is indeed a strong drawback for the material that prevents its wider use in orthopaedic surgery. This is the reason why requirement for Titanium coating on PEEK has been recognized pretty early.
Thanks to an extensive know how in osseointegrative coatings on medical devices, Medicoat has extended its Medipure ™ titanium coating technology by vacuum plasma spray (VPS) to organic substrates like PEEK, PEKK, CFR PEEK and long-fibre reinforced materials, and applied it to several spline implants like cervical and lumbar cages, pedicle screws and cranial plates. The well-integrating Titanium surfaces along with increased surface area of the rough coating improve the poor osseintegration of PEEK-based medical devices. Using cutting edge plasma spray technology, Medicoat is able to fully coat PEEK or PEKK implants with complex geometries like fenestrated open structures, promoting osseointegration not only on flat bone contacting surfaces but within the structure too, supporting bone growth through the entire implant.
Recently CE marked and FDA approved PEEK medical devices coated by Medicoat will soon be launched on their respective markets.

When filling powder feeders from the reservoir, harmful dust is inevitably released into the ambient air due to the volume displacement. Further more, depending on the nature of the powder, an ignitable cloud of dust may form, which can lead to fires or explosions in the case of improper filling operations or equipment (ATEX zone).
The newly developed filling-suction device SAFU supports the safe and reliable filling of the Medicoat powder containers of the type Flowmotion and disc conveyors.
The hopper is made of stainless steel and has a suction port to safely dispose of the dusts in the customer’s dust filter.
The filling-suction device allows a safe and clean working and saves additional cleaning effort.
eifeler Holding GmbH & Co. KG, a leading global provider of medical coatings, acquired a minority interest in Medicoat AG on October 25, 2017.
With this investment, eifeler not only deepens its strong know-how in the field of medical coating technology, but also extends its expertise to the development and production of complete coating systems and consumables for thermal spraying.
eifeler group has been active in the growing market of high-tech coatings for 30 years and ranks among the leading companies in the coating market worldwide. Following the divestiture of its tool coating division in 2013, the company today focuses on developing and applying innovative coating solutions to a variety of industries, in particular medical technology, with highly qualified engineers, physicists and chemists in its own research and development laboratories and coating centers.
Founded in 1989, Medicoat AG, based in Switzerland, is an innovative company in the field of thermal spraying technology with a focus on plasma spraying. Medicoat offers complete coating systems including wettable powders and develops spray coatings for medical and other industrial applications. Medicoat specializes in atmospheric and vacuum plasma spraying (APS, VPS) for coatings of medical implants with very pure titanium and hydroxyapatite in optimized crystallinity. In addition, the company serves a variety of international OEMs in the orthopedic industry as a contract manufacturer with the coating of implants. In addition to its head office in Mägenwil (Switzerland), Medicoat operates sites in Wohlen (Switzerland), Hunzenschwil (Switzerland) and Etupes (France).
In July 2017 Kermetico Inc. and Medicoat AG started a cooperative project to provide a novel coating equipment system and solutions for European and North American markets. Both partners plan to provide a multifunctional plasma+HVOF+HVAF system by the end of this year.
Kermetico, Inc. is a California corporation established in 2006. Kermetico designs, builds and supplies High Velocity Air Fuel (HVAF) and High Velocity Oxy Fuel (HVOF) spraying equipment. Kermetico has created HVAF and HVOF systems for automated, hand-held and internal diameter coating applications. Kermetico systems provide technologically efficient ways to spray tungsten carbides, chromium carbides, metals (Al, Ti, Sn) and alloys (Ni-, Fe-, Co-based, MCrAlY, Inconel, Hastelloy).
Medicoat AG is a Swiss-based innovative company working in the thermal spray industry, established in 1989 and specialized in atmospheric and vacuum plasma spraying (APS, VPS) for coatings of medical implants. Medicoat offers complete coating systems and develops spray coatings for medical applications in particular very pure titanium and hydroxyapatite with adapted crystallinity.
At formnext, one of the most elaborate and striking displays of additive manufacturing products and services, from 15 to 18 November 2016 manufacturers of machines, materials and software solutions presented their products. Most major companies in 3D printing and AM were present, and many had very large and impressive exhibits. If the event had a theme, it was metal additive manufacturing.
In processes such as direct metal deposition the quality of the applied methods depends to a large extent on the precise powder feed. Here powder feeder Flowmotion from Medicoat could prove its strengths. The powder material, which is stored under inert gas conditions, is supplied to the burner for uniform material application by the device via the oscillating conveying channel and follower systems.

On 24 June 2014, as part of the international trade fair for surface treatments & coatings three innovations from various industrial sectors were honored with the Stuttgart Surface Technology Award 2014. 1st place was given to the Airbus Group for surfaces based on TiO2 nanotubes reducing ice adhesion to aircraft. The second place went to the cooperative project of CeramTec GmbH and Medicoat AG – »Bone grows to ceramic implants through new coating technology.“
3rd place was awarded to Hartchrom Schoch GmbH for the subject »Anti-Stokes crystals in chemically or electrochemically generated surface layer systems highlight products safely«.
From 21 to 23 May Barcelona is the venue for the ITSC 2014 – International Thermal Spray Conference & Exposition. At ITSC 2014 Medicoat will display state of the art thermal spray equipment and materials. Our experts will be at hand to discuss highlighted products such as Flowmotion, our new powderfeeder with linear actuator.
We will also introduce the latest generation of system visualization and control, which meets the high demands and requirements of production and monitoring for sensitive areas such as aviation and medicine.
The current issue no. 8-2013 of Focus Aargau Magazine reports under the title „A bone-hard business“ on the Medicoat AG. Founder Heiko Gruner provides information about the company, the products and the Canton of Aargau as a business location.
