What Is A Medical Stent Used For?

A medical stent is a small, mesh tube that is inserted into a blocked or narrowed passage in the body to keep it open. Stents are used for the following purposes:

- Coronary stents - Used to open blocked heart (coronary) arteries. This helps improve blood flow to the heart muscle and reduce the risk of heart attack.

- Peripheral stents - Used to open blocked arteries in the legs, arms, kidneys, and other areas to improve circulation. 

- Carotid stents - Used to open narrowed carotid arteries in the neck that supply blood to the brain. This helps reduce stroke risk.

- Pulmonary stents - Used to open narrowed pulmonary arteries that supply blood to the lungs.

- Biliary stents - Used to open blocked bile ducts in the liver to allow proper bile drainage. This helps treat jaundice or gallstones.

- Esophageal stents - Used to open narrowed areas of the esophagus making swallowing difficult.

- Colonic stents - Used to open blocked sections of the colon often due to cancer.

- Ureteral stents - Used to open narrowed spots in the ureters, the tubes that carry urine from the kidneys to the bladder.

- Airway stents - Used to open trachea or bronchus blockages making breathing difficult. 

So in summary, stents are designed to prop open nearly any narrowed or blocked passage in the body and restore normal function. The type used depends on the specific blocked area needing treatment.
