There are several types of Foley catheters, each designed for specific purposes. The most common types include: - Latex Foley Catheters: These are flexible and commonly used in short-term situations. - Silicone Foley Catheters: Ideal for patients with latex allergies or for long-term use. - Hydrogel-Coated Catheters: These provide additional comfort and reduce the risk of urethral irritation.
