The Folysil® silicone indwelling catheter features a significantly larger lumen than latex versions of the same FR size. This helps to reduce obstruction and inhibit encrustration. The larger-diameter eyelets allow for better drainage, while an atraumatic tip adds to ease of insertion. The Folysil® indwelling catheter also features a radio opaque stripe in a transparent shaft for easy detection in an x-ray.
