LoFric Primo - 16" Hydrophilic Coude Catheter uses Urotonic Surface Technology, which creates low friction between the catheter and urethra to reduce irritation. The saline content on the intermittent catheter's surface acts like urine. LoFric intermittent catheters are activated by water that is included in the package. The hydrophilic coating ensures that the surface remains moist during the entire use of the catheter. Upon removal, these intermittent catheters remain slippery, helping to prevent damage to the urethra. Fits easily into a purse or shirt pocket. Latex free. Formerly manufactured by Astro Tech. French sizes: 14, 16.
