Foley catheters are flexible tubes that are inserted through the urethra and into the bladder to drain urine. Made out of silicone or latex, they have an inflatable balloon at the tip that is filled with sterile water once inserted to hold the catheter securely in place. Catheters come in various sizes depending on the patient's anatomy. https://www.coherentmarketinsights.com/market-insight/foley-catheters-market-2808
