A Foley catheter, named after its inventor, Dr. Frederic Foley, is a flexible tube inserted into the bladder to drain urine. It consists of a drainage lumen, and an inflatable balloon at the tip, and may include additional lumens for irrigation or medication administration.
Foley catheters are commonly used in medical settings for various purposes, including urinary retention, monitoring urine output, and facilitating bladder drainage during surgery or incontinence management. They are available in different sizes and materials, with silicone being a popular choice due to its flexibility and reduced risk of allergic reactions compared to latex. Proper insertion and care are essential to minimize the risk of complications such as urinary tract infections and tissue irritation.
