Modifies surface properties of a material using ion bombardment without adding a coating layer to the surface.

Ion implantation is a highly controllable process for modifying physical and chemical surface properties of materials. Many surface properties can be improved with ion implantation including hardness, wear resistance, resistance to chemical attack, and reduced friction. The process can be applied to virtually any material, including most metals, ceramics and polymers.

Ion implantation is a low temperature process that is used to selectively modify the surface of the substrate without detrimentally affecting bulk properties. The process is extremely controllable and reproducible and can be tailored to modify different surfaces in desired ways. Although it is a line-of-sight process, specialized fixturing is used to uniformly treat complex geometries.

Examples of components treated with ion implantation are Ti and Co-Cr orthopedic prostheses, which are made harder and more wear resistant, and silicone catheters, which are made less tacky and resistant to biofilm formation.

Ion Implantation: Reduced Wear and Fretting with IonGuard®

N2 Biomedical’s proprietary IonGuard® process utilizes direct ion beam bombardment to create a hard, low friction, and hydrophilic surface without changing the bulk properties of the device. This low temperature process has been used to treat millions of medical device implants including metal knees and hips and orthodontic arch wires.

IonGuard® treated Co-Cr heads are 17-29% smoother than untreated. Multiple clinical studies with multi-year follow-up have demonstrated up to a 40% reduction in wear rates for mating polyethylene surfaces. Wear simulation testing demonstrated IonGuard® treated heads superior to Titaninum Nitride coated Co-Cr and Alumina heads over 5 million cycles.

IonGuard® treated Titanium femoral knees show no signs of wear after 5 million cycles and titanium hip components release 35 times less metal than untreated parts.

Ion Implantation: IonGlide

The IonGlide Ion Implantation surface treatment has been clinically proven to fight infections on polymeric medical devices by changing the surface morphology to prevent the formation of biofilm.

This proprietary, low temperature process is suitable for a variety of silicone and polyurethane implants such as stents, indwelling catheters and shunts.  Ion beam bombardment has been shown to enhance the properties of polymeric devices without adding any material to the surface.

In vivo testing of competing coating systems showed IonGlide superior in preventing the formation of biofilm on myrongotomy tubes after ten days while competitors showed dense inflammatory film adhesion.
