Silicone coated catheters, including Nelaton catheters, are medical devices used for urinary catheterization. They are commonly used in healthcare settings for draining urine from the bladder when a patient is unable to urinate naturally. The silicone coating on the catheter provides a smooth and lubricated surface, making insertion and removal more comfortable for the patient and reducing the risk of damage to the urethra.
