Medical Stents can be used for vascular and other interventional procedures in the body, both diagnostic and therapeutic. They are normally advanced over a guidewire which has been maneuvered to, and just past, the treatment site, so clear understanding of the type, size and material of the stent is important in specifying an appropriate guidewire.

Angioplasty Stent – Animated stent insertion

Angioplasty Stent
Keeps open narrowed arteries (stenosis) and treats blood clots (thrombosis) in the coronary vasculature.

Biliary Stent
Keeps open bile ducts that are obstructed by: tumors from Pancreatic cancer, injury to the ducts, duct inflammation, or pancreatitis.
[ Related: Duodenal, Pancreatic, Colonic stents ]

Cerebral Stent
Keeps open stenosed sites in the cerebral vasculature.

Colonic Stent, or Colorectal Stent
Keeps open areas of the colon obstructed by tumors.
[ Related: Biliary, Duodenal, Gastroduodenal, Pancreatic, Oesophageal stents ]

Coronary Stent
Keeps open stenosed sites in vasculature of the heart.

Carotid Stent
Keeps open stenosed sites in carotid artery of neck.

Duodenal Stent
Keeps open areas of the small intestine that are obstructed by tumors.

Gastroduodenal Stent
Keeps open areas of the small intestine that are obstructed by tumors.
[ Related: Biliary, Colonic, Pancreatic stent, Wallstent, Song Duodenal stent ]

Pancreatic Stent
Keeps open areas within the pancreatic duct that are obstructed by tumors, pancreatic stones, pancreatitis or other strictures.
[ Related: Biliary, Colonic, Duodenal, Gastroduodenal, Oesophageal stents ]

Prostatic Stent
Can be temporary or permanent. Assists urination by keeping the urethra open where an enlarged prostate compresses it.

Oesophageal Stent
Keeps open areas of the esophagus that are obstructed by tumors.
[ Related: Biliary, Colonic, Duodenal, Gastroduodenal, Pancreatic stents. Wallstent. Song Duodenal stent ]

Stent Grafts
Fabric supported by metal; used during Endovascular Surgery support weak points in arteries, such as aneurism sites.

Ureteral Stent (Ureters)
Keeps ureters open to assure drainage from kidney to bladder. Temporary use during kidney stone crises, or permanently sited if there are tumors compromising ureter drainage.

Vascular Stent (vessels other than coronary)
Keeps open stenosed sites in the vasculature
