What is a Catheter?
A catheter is a flexible tube that is inserted through a narrow opening into a body cavity, particularly the bladder, for removing fluid. That is the definition of the word catheter but there are many differences between them. Catheters are generally made from silicone, latex, or a combination of both. One type of catheter is called a Foley catheter. Once it is inserted into the bladder, a small balloon at the tip is inflated so the catheter can be held in place inside the bladder. Another type of catheter is referred to as an "intermittent catheter". Similar to the Foley, it is inserted into the urethra and then it is pushed into the bladder. Unlike the Foley, once the bladder is drained, it is removed immediately and discarded. People who use intermittent catheters use several a day while people who use Foley catheters use the same one for a set period of time. [More]
