Mounted over a balloon, expansion of the balloon
Causes deployment of this type of stent. Precise positioning is required and is more rigid. These are not placed over
joints as can fracture.
Stent Grafts
Stent-grafts represent a combination of stent and surgical b

Atherectomy Device
Chiba Needle Used to gain access to bilary ducts. This can be done under Fluoroscopic Or USG guidance.
Biliary Internal-External Drain This has proximal as well as distal drainage holes that allow drainage of bile
proximal to lesion externally. if the drain is internalized, that is the lesion is crossed and distal end is placed in the
