A Foley balloon catheter is a sterile medical device that doctors use to safely drain urine from the bladder. It does this by having a small inflatable balloon located near the tip. It is available in 2-way and 3-way styles and can be used for routine drainage, surgical recovery, and irrigation. It is single-use and EO-sterilized and has sizes ranging from 6 FG to 30 FG and can be used for adults and pediatric patients.
