Foley Catheter
A Foley catheter (pronounced: /ˈfoʊliː ˈkæθɪtər/) is a type of catheter that is typically used to drain urine from the bladder. It was named after its inventor, Frederic Foley, an American urologist.
Etymology
The term "Foley catheter" is derived from the name of its inventor, Dr. Frederic Foley, who developed the device in the 1930s. The word "catheter" comes from the Greek word "katheter" which means "to let or send down."
Description
A Foley catheter is a flexible tube that is passed through the urethra and into the bladder to drain urine. It is unique in that it has an inflatable balloon that can be filled with sterile water to hold the catheter in place within the bladder. The catheter is typically made of latex, silicone, or a type of plastic called polyurethane.
