Abstract

Devices, methods, and kits are presented that allow for simplified stent placement and stent retention in a biological vessel other than a blood vessel, and especially biliary stent placement in an antegrade manner. The devices and methods advantageously allow for shortened imaging and stent placement time, and substantially improve tolerability and/or retention of the stent in the vessel, and in further beneficial aspects, contemplated stents form a composite fluid path to facilitate drainage of the vessel. Still further, the devices and methods presented herein reduce or even entirely eliminate partial deflation of the peritoneal space during imaging and stent placement and so prevent exposure of operating personnel to vented gases carrying harmful agents.
