A stent is made from a coiled wire and is very smooth along its length and as well its ends. The stent is thus highly atraumatic to patients, and because of its smooth surfaces, it presents a surface to which it is difficult for microbes to cling. The stent may be used in a minimally invasive procedure, such as for a ureteral stent, and may also be used percutaneously. Similar stents may be used in other body areas, such as in draining the biliary tract, the gastro-intestinal tract, hepatic procedures, and in vascular procedures as well.
