    Catheters and medicals tubes are widely used to introduce pharmaceuticals and nutrients into arteries and veins, and to drain fluids or urine from urethra or the digestive organs. It is well known that illuminated TiO2 photocatalysts can decompose most noxious or toxic organic compounds. We studied the properties of titanium dioxide layers created by pulsed laser deposition from pure titanium and titanium dioxide targets with the goal to develop urethral catheter using TiO2 coated plastic tube. To reach crystalline structure at low substrate temperatures the radio-frequency discharge between the target and the substrate was implemented. The crystalline structure of layers was determined by X-ray diffraction and Fourier Transform Infrared Spectroscopy. Morphology was studied by atomic force microscopy (AFM). Using RF discharge, mixture of anatase and rutile was found at substrate temperature of 90°C (which was reached only by RF discharge).
