Introduction to Catheter

Catheter is a medical device that has been used for various purposes for thousands of years. In ancient times, hollow tubes made of metal, wood, or ivory were used for medical procedures, including draining urine. The word, "catheter," originates from the Greek word, "kathetḗr," which means "to let down" or "send down".The earliest written evidence of catheters being used dates back to 3000 BC, when the ancient Egyptians used reeds as catheters to treat urinary tract infections. Ancient Greeks and Romans also used metal catheters to treat bladder stones and other urinary problems.

The First Modern Catheter

The modern catheter that is commonly used today was invented by Benjamin Franklin in 1752. Franklin, who was a scientist, statesman, and inventor, created a flexible tube made of metal that could be inserted into the bladder through the urethra. At that time, the catheter was primarily designed to remove urine from the body in cases where a person was unable to do so naturally.Franklin's catheter was made of a long metal coil that could be extended or shortened depending on the length required. This design allowed for easier insertion into the bladder and minimized the risk of injury to the urethra.

Improvements over Time

Over time, the catheter has undergone numerous changes and improvements to make it more comfortable, functional, and safer to use. In the 1800s, rubber replaced metal as the primary material used for making catheters, making them more flexible and easier to insert. This innovation also helped to reduce the risk of injury to the urethra during insertion.In the mid-20th century, catheters began to be made from plastics, which resulted in a safer and more hygienic device. Today, catheters are made from a variety of materials, including latex, silicone, and polyurethane. The availability of different materials and designs means that catheters can be tailored to suit the needs of individual patients for their specific conditions.In addition to materials, the design of catheters has also undergone significant changes. Innovations such as pre-lubricated catheters, catheters with curved tips, and closed-system catheters have made catheterization less painful and more convenient for patients.


Although ancient civilizations used rudimentary catheters made of reeds or metal, it was Benjamin Franklin's invention of the modern catheter in 1752 that revolutionized the medical device. The catheter has undergone numerous changes and improvements over the centuries, from the use of rubber to plastics and other materials to innovations in design that make catheterization less painful and more hygienic. Today, catheters are an indispensable medical device used to treat a wide range of conditions.

Who Invented the Catheter?

The catheter is a medical device used to treat a variety of conditions related to the bladder and urinary tract system. Its invention can be traced back to ancient times, with evidence of primitive catheters found in Egyptian mummies dating back to 1500 BCE. However, it was not until the 19th century that the modern catheter was invented.

The credit for inventing the modern catheter is often given to Benjamin Franklin. In 1752, Franklin’s brother had died due to bladder stones. In response, Franklin developed a flexible catheter that could be inserted into the bladder to remove urine and clear blockages. Franklin’s catheter was made of brass wire and had a flexible stem that could be bent to navigate through the urethra and reach the bladder.

Over the years, the catheter was modified and improved upon by various medical practitioners and inventors. In the 1800s, Joseph-Frédéric-Benoît Charrière, a French instrument maker, developed a standardized catheter sizing system. This system made it easier for medical professionals to select the right size catheter for their patients.

In 1874, Thomas W. Foley invented the Foley catheter, which is the most commonly used type of catheter today. The Foley catheter is an indwelling catheter that has a small balloon at the end. Once it is inserted into the bladder, the balloon is inflated to keep the catheter in place. This type of catheter is often used for long-term urinary catheterization.

Types of Catheters

There are several types of catheters available, each designed to meet specific medical needs. The most commonly used catheters are indwelling catheters, intermittent catheters, and specially designed catheters.

Indwelling Catheters

Indwelling catheters, also known as Foley catheters, are the most commonly used types of catheters. They are inserted into the bladder and left in place for an extended period of time. They have a small balloon at the end, which is inflated to keep the catheter in place.

Indwelling catheters are typically used for patients who are unable to urinate on their own or have conditions that hinder their ability to do so. They may also be used for patients who need to monitor their urine output, such as those who have undergone surgery.

However, there are risks associated with the long-term use of indwelling catheters such as urinary tract infections and bladder spasms. Therefore, these catheters are typically used as a last resort when other, less invasive treatment options have failed.

Intermittent Catheters

Intermittent catheters are for single use, and they are removed immediately after draining the bladder. They are often used by those who are unable to control their urine because of conditions like spinal cord injuries, neurological conditions, or prostate problems.

Intermittent catheterization involves inserting the catheter into the bladder at scheduled intervals to drain urine. This reduces the risk of infections and other complications associated with long-term catheterization.

Intermittent catheters are available in various sizes to accommodate different body types, and they are typically made of silicone or sterile latex. They are also available with pre-lubricated tips, which makes insertion more comfortable.

Specially Designed Catheters

Specially designed catheters are used for specific purposes, like for female or pediatric patients. These are shorter and smaller than typical catheters as they need to fit better, and they have a shape that makes them easier to use.

Female catheters are typically shorter and more flexible than male catheters to accommodate the shorter urethra. Pediatric catheters are even smaller in size and often have fun designs to make the experience less intimidating for young patients.

In conclusion, the catheter has a long and interesting history, dating back thousands of years. While the modern catheter has evolved significantly since its inception, its purpose remains the same – to provide much-needed relief to patients suffering from urinary tract and bladder-related conditions.
