Hydrophilic catheters are a special type of intermittent catheter which contains a coated surface that, when activated by water, becomes super slick, making catheterization smooth and almost effortless. The most basic hydrophilic catheter requires tap water to activate. Many contain a water packet within the package. When squeezed, the water packet ruptures and releases the water or saline, which then wets the catheter to activate the super slick coating. Examples are the PECO Hydrophilic, McKesson, Magic3, FloCath Quick, Hi-Slip, LoFric, and Cure Hydrophilic. Hydrophilic catheters that do not require the addition of tap water or a water packet to activate them include the SpeediCath and VaPro, which are basically ready-to-use right out of the pack.
