BD Intermittent Coude 16" Catheter has a bent, tapered tip for easier insertion and maneuverability around scar tissue or a swollen prostate. These uncoated catheters are single use and sterile. They are not meant to be reused. Each curved tip catheter has two heat-polished eyelets to make insertion and drainage more comfortable. The funnel of the catheter is color coded for easy identification of french size. Each funnel also has a help guide notch to help guide the proper angle for insertion. The BD intermittent catheter is not made with DEHP, BPA, or natural rubber latex.
