Foley catheters feature flexible silicone or latex tubing with two
lumens, or channels. The first lumen is open at both ends. It
drains urine from the bladder into an exterior container. The second lumen has a port at the entry point and a balloon at the
bladder end.

The Foley catheter uses gravity to drain the bladder of urine.
First, a medical technician threads the balloon end of the sterile,
flexible tube through the urethra, which channels urine under normal circumstances. The urethra provides a direct path to the
bladder. Once the catheter is in place, the technician squirts saline solution through the other lumen to fill the balloon now
inside the bladder. The filled balloon keeps the Foley catheter in place for periods ranging from a couple of hours to a few days.
