Nelaton catheters are used for short-term urethral catheterization. They soften at body temperature, allowing for easy and painless insertion. Nelaton Unomedical catheters are individually packaged and sterilized for immediate use. They are manufactured in the European Union from medical-grade PVC, a non-toxic, pyrogen-free plastic. They are sterile and intended for single use only. Disposal is required after use.
