Camstent is developing a surface coating that resists bacteria colonisation and inhibits biofilm development
Coating catheters should decrease CAUTI
Catheter acquired urinary tract infections (CAUTI) are the biggest cause of HAIs . Solutions that can help prevent or reduce catheter-related infections will lead to significant improvements in clinical outcomes and substantial cost savings to healthcare providers.
Catheters with antibacterial coatings can be a way to reduce or retard the formation of the bacterial biofilm that leads to CAUTIs .

But current coating technologies don't work
Coated catheters on the market, which mainly rely on silver hydrogel or antibiotics, have proven to be largely ineffective at preventing the growth of bacterial biofilm and, therefore, reducing CAUTIs .
Multiple clinical trials report little to no efficacy for existing products Where some positive effects were observed, they were short-lived, often lasting as little as a few hours before dissipating .
