Foley Catheters

Foley Catheters are designed to remain in a singular place, and function because they stay put. To accomplish this, the catheter has a balloon on the end that is inside the body. After the catheter is inserted into the body, this balloon is injected with sterile water which cause the balloon to inflate. This balloon keeps the catheter inside the bladder so that it will not cause an issue by escaping the body.

While such catheters are designed to remain in the body for an extended period of time, they must be monitored to prevent urinary tract infections. While the function of the Foley catheter is to drain urine, you must keep in mind that the longer the catheter remains inside the body, the greater the likelihood of infection. Commonly referred to as an indwelling catheter, these Foley catheters allow urine to be collected and then removed from the body.
