Camstent is developing coatings to be bacteria-phobic

The coating will be, when finalised, 'non-stick', preventing adhesion and colonisation; rather than killing the organisms

Biofilms are thin layers of microorganisms, usually protozoa and bacteria, which aggregate on exposed surface of medical devices. They directly irritate the surrounding tissue and release toxins that cause inflammation and infection. Camstent's surface coating inhibits biofilm formation of pathogenic microorganisms, potentially preventing patients from developing infections and potentially protect against possible tissue damage caused by these organisms.

Camstent coatings are free of toxins and antibacterial agents.

The absence of antibacterial agents means that the Camstent coated catheter does not contribute to bacterial resistance, thereby minimising the potential side effect of stimulating resistant organisism that is often a side effect of treating HAIs.

The coated catheter surface reduced colonisation ten-fold in independent and comparative laboratory tests.

We use proprietary polymers, formulated from two acrylic components.

One is optimised to prevent bacteria from colonising the device surface, while the other imparts flexibility required for clinical safety.

Laminated onto surfaces as thin films, this coating inhibits surface colonisation of catheters by organisms commonly found in the urinary tract, implicated in hospital acquired infections. Variations in the component molecules yield other formulations able to resist blood products or protein attachment across a wide range of substrate materials used in medical devices.

The Camstent bacteria-phobic coating technology offers unique clinical advantages:

  • Demonstrably superior resistance to biofilm development versus currently marketed solutions
  • Inert coating material, with documented compliance with laboratory biocompatibility standards for avoiding toxicity, irritation, and sensitisation. 
  • Durable coating that remains attached to the catheter surface, inside the lumen and across the surface, throughout normal use
  • Smooth, thin surface coating aiming to minimise discomfort for the patient
  • Indications for use, handling, and training are unchanged from use of uncoated catheters.
  • Non-pharmacologic and does not kill bacteria, avoiding the emergence of resistant organisms.
