The term "stent biliary V-E-013-8.5FR (J Sharp)" refers to a specific biliary stent model used in medical procedures to maintain bile duct patency. Here's a breakdown of its features:

• Stent: A device inserted into a duct or vessel to keep it open. In this case, it's for the bile duct.
• Biliary: Relating to the bile ducts, which carry bile from the liver and gallbladder to the small intestine.
• V-E-013: Likely the model or version identifier of the stent, indicating a specific design or type.
• 8.5FR: The French gauge measurement of the stent, where 8.5 French corresponds to a diameter of about 2.83 millimeters (1 Fr = 0.33 mm).
• J Sharp: Refers to the design or shape of the stent. In this case, "J Sharp" likely indicates a stent with a sharp "J" shape at one end, designed to help with positioning and prevent migration within the bile duct.

This type of stent would be used to treat conditions like bile duct obstructions due to strictures, stones, or malignancies.
