Stent

What is a Stent?

A stent is a tiny tube that doctors use to help keep narrow or blocked parts of the body open. It is made from special bendable materials or metals. Stents help blood or other fluids flow properly by staying in place inside blood vessels or other tubes in the body.

Where are Stents Used?

Stents can be used in many places in the body. Coronary stents are placed in the heart to keep blood vessels open. Ureteric stents help keep the tubes that carry urine from the kidneys to the bladder open, especially if a kidney stone is blocking the way. Prostatic stents help men urinate more easily when their prostate gland is larger than normal. Other stents can help with problems in the brain, neck, legs, and even the tubes that carry food and fluids.

A Little History

The idea of a stent began with Charles Stent, an English dentist, in the 1800s. He worked with a special material that later helped make stents possible. Using stents in the heart started in 1986 when doctors Jacques Puel and Ulrich Sigwart used them during heart procedures. Today, stents are carefully checked to make sure they are safe before they are used in patients.

Different Types of Stents

There are many kinds of stents for different needs. Some are made from simple metal, while others slowly release medicine to help keep blood vessels open. Some stents are designed to dissolve over time, allowing the body to return to its natural state. No matter the type, stents are important tools that help many people stay healthy.
