Mechanism of action

The Bactiguard Infection Protection (BIP) technology is based on a very thin noble metal alloy coating, consisting of gold, silver and palladium, firmly attached to medical devices. When in contact with fluids the noble metals together create a galvanic effect.

Reduction of microbial adhesion

The galvanic effect creates a micro current that reduces microbial adhesion to the catheter material, which decreases the risk for biofilm formation leading to infections.

Safe for patient and environment

The amount of noble metals at the surface is very low and below all safety limits for each metal, and there is no release of any toxic or pharmacological quantities. This makes the technology both tissue-friendly and safe as opposed to traditional coating technologies that often depend on the release of substances that kill bacteria, e.g. high concentrations of silver ions, chlorhexidine or antibiotics.1

To date, more than 170 million Bactiguard coated catheters have been sold for patient use, with no reported adverse events related to the coating.
