The Guiding Catheter is a sterile device inserted through a compatible flexible endoscope to aid in the initial placement of a stent, typically into a pancreatic or biliary duct in order to maintain patency. It is made of polytetrafluoroethylene (PTFE) with a radiopaque marker on the distal end. This is a single-use device.
An assembly of sterile devices inserted through a compatible flexible endoscope to implant a stent, typically into a pancreatic or biliary duct in order to maintain patency. It typically consists of a positioning catheter onto which the stent is loaded, a guiding device (commonly known as an introducer or guidewire) that aids the initial placement of the stent, and a pusher catheter that holds the stent in place during withdrawal of the other component devices. It is commonly made of polytetrafluoroethylene (PTFE) [Teflon], or polyethylene (PE). This is a single-use device.
