A Foley balloon catheter is a sterile medical device doctors use to drain urine safely from the bladder. It stays in place through a small inflatable balloon near the tip. Available in 2-way and 3-way designs, it supports routine drainage, post-surgery recovery, and bladder irrigation. EO-sterilized and single-use, these catheters come in sizes 8 FG to 30 FG and suit both adult and pediatric patients for short- and long-term use.
