A stent introducer is a medical device used to facilitate the placement of stents into the body. It is typically a catheter system designed to guide and deploy stents into specific locations, such as blood vessels or the biliary tract.

Key Features of Stent Introducers
Design: Stent introducers are usually composed of a sheath and a pushing catheter. The sheath provides a protective covering for the stent during insertion, while the pushing catheter is used to advance and deploy the stent.
Materials: Made from flexible materials like plastic or silicone to ensure smooth passage through the body’s lumens.
Wire Guidance: Often uses a wire guide (e.g., 0.035 inch) to enhance precision and control during stent placement.

Advantages
Precise Placement: Allows for accurate deployment of stents, reducing complications and improving procedural success.
Minimally Invasive: Facilitates stent placement through small incisions or natural body openings, minimizing tissue trauma and recovery time.
