Silicon Catheters are meant for very long term implantation. 100% silicon construction from highly bio compatible and toxin-free silicone elastomer. The non-stick surface of silicone makes it highly resistant to encrustation. Technically advanced process forms the balloon as an integral part of the catheter, eliminating rough edges where the balloon meets the shaft. Sizes: 8, 10, 12, 14, 16, 18, 20, 22, 24 & 26 FR
