Deployable Concepts for Oesophageal Stents

Abstract

Stents are flexible structures capable of being folded into small dimensions allowing their passage into the problematic locations in the body and then being expanded. Their prime usage is to treat patients with obstruction at several sites in the body. For example, they are used to open blocked coronary arteries and large veins, to treat obstructions to breathing in the trachea and bronchus, and those in the prostate to allow the passage of urine [1].
