Non-vascular catheter introduction set

A non-vascular catheter introduction set is a sterile, single-use system designed to facilitate the percutaneous insertion of non-vascular catheters (such as drainage catheters) into body cavities or lumens like the biliary tract or ureter. It typically includes an introducer needle, sheath, and dilator to create a pathway for the catheter, following the Seldinger technique without involving blood vessels.

These sets are regulated as invasive devices and are generally classified based on their risk profile, though classification varies by jurisdiction. They are supplied as complete, pre-sterilized kits for one-time clinical use, ensuring minimal contamination risk during procedures like biliary or ureteral drainage.
