Abstract
An stent delivery system may include a delivery device and a tubular body having a lumen sized to slidably fit about an outer diameter of the delivery device and a drainage stent having an anchoring mechanism, wherein the delivery device includes a constraining member configured to engage an external portion of the tubular body at the proximal end of the delivery device. A method of delivering a stent may include inserting a tubular body into the port of an endoscope, inserting a stent delivery device and a stent having an anchoring mechanism into the tubular body, wherein the delivery device includes a constraining member configured to engage and retain the tubular body at the proximal end of the delivery device, advancing the drainage stent distally through the tubular body, sliding the tubular body proximally, and engaging an external portion of the tubular body with the constraining member.
