Revêtements pour dispositifs cardiovasculaires

Conçu pour augmenter la durée de vie des composants implantables

Ionbond Medical Portrait
cardiovescular implant heart cancer treatment

Les dispositifs d'implant cardiovasculaire comprennent les stimulateurs cardiaques, les stents coronariens, les valves cardiaques, les anneaux d'annuloplastie et les fils guides. Le Medthin™ 43 ADLC, un revêtement dense à base de carbone, convient idéalement aux composants cardiovasculaires implantables, en raison de propriétés qui contribuent à l'augmentation de la durée de vie des dispositifs et réduisent la probabilité d'une nouvelle intervention chirurgicale pour les patients :

  • Hémocompatibilité
    • Réduction de l'absorption des protéines de haut poids moléculaire sur les matériaux revêtus de Medthin 43 ADLC
    • Réduction de l'adhérence/du dépôt de caillots sanguins sur l'ADLC, par rapport aux surfaces de Ti
  • Faible coefficient de frottement
  • Réduction de la libération d'ions

Medthin™ 11 - Implants

A possible alternative to TiN - in line with existing predicates

Medthin™ 11 coating is known to reduce ion release from implant substrates materials such as CoCr, SS or TAV. The coating is applied with thickness of about 5µm and it has adhesion strength to metal substrates higher than 1.0GPa leading to an  improved abrasion resistance when compared with uncoated CoCrMo. Titanium Niobium Nitride (TiNbN) is deposited with latest generation Ionbond technologies showing a polycrystalline cubic structure with a fine and very dense structure, roughness (Ra) values below 0.05µm, ideal for articulating zones.  The coating coverage is rather uniform on external surfaces whereas for inner surfaces a Ionbond proprietary technology can be applied in some cases.

Ionbond  can currently deliver coating service ”me too” of “Medthin™ 11 TiNbN on Implants” from Europe and Asia using large coating chambers at attractive prices.

Medthin™ 42 - Implants

Probably the best (hard) coating for implants

Medthin™ 42 coating combines high adhesion strength with low UHMWPE wear and nearly no ion release from the implant substrate reaches the body fluids from the patient. The coating is applied with thickness of about 5µm and it has adhesion strength to metal substrates higher than 1.5GPa. Chromium Nitride + Diamond Like Carbon (top layer) for implants, is deposited with an hybrid system, a combination of PVD high energy sputtering and Plasma Assisted Chemical Vapor Deposition Technologies (PACVD). The top layer is amorphous and has excellent sliding characteristics with extremely low friction coefficients against many materials including ceramic.

The coating coverage is rather uniform on external surfaces.  Ionbond  can currently deliver coating service of “Medthin™ 42 DLC on Implants” from America, Europe and Asia.

Medthin™ 43 - Implants

The high class coating for implants

Medthin™ 43 coating is excellent to improve articulating joints such as those of “Coating on UHMWPE” where polyethylene wear and ion release from substrates (CoCr, SS, TAV, etc)  is reduced nearly to zero. The coating is applied with thickness of about 3 µm and it has adhesion strength to metal substrates higher than 0.8 GPa. Amorphous Diamond Like Carbon (ADLC) is deposited with latest generation Plasma Assisted Chemical Vapor Deposition Technologies (PACVD) showing an amorphous phase virtually with no pores and roughness (Ra) values below 0.02µm, ideal for articulating zones. The coating coverage is rather uniform on external surfaces whereas for inner surfaces a Ionbond proprietary technology can be applied in some cases.


Ionbond  can currently deliver coating service of “Medthin™ 43 ADLC on Implants” from Switzerland, France and UK and the coating properties/characteristics have been filed in a FDA master file (MAF) number 1647. The MAF can be referred upon request and common agreement with Ionbond.

Medthin™ 60 - Implants

The high oxidation resistance coating

Medthin™ 60 coating is particularly suitable for improving articulating joints such as those of “Coating on UHMWPE” where polyethylene wear and ion release from substrates (CoCr, SS, TAV, etc)  is strongly reduced. The coating is applied with thickness of about 5 µm and it has adhesion strength to metal substrates in the GigaPascal range. The ZrN layer improves UHMWPE abrasion resistance >65% measured on knee simulator tests compliant with ISO 14243. Zirconium Nitride (ZrN) is deposited with latest generation technologies showing a polycrystalline cubic structure with a fine and very dense structure,  roughness (Ra) values below 0.05µm, ideal for articulating zones. The coating coverage is rather uniform on external surfaces while internal surfaces are difficult to coat.

Ionbond  can currently deliver coating service of “Medthin™ 60 ZrN on Implants” from multiple coating centers.
