Methods and systems for deploying luminal prostheses

摘要

Stents and other luminal prostheses may be introduced to body lumens, such as ureters, within a lubricious sleeve. The sleeve may be packed within a distal end of the stent so that it may be everted and withdrawn to cover an exterior surface of the stent as the stent is advanced. The stent is typically advanced using a separate pusher member which is engaged against a proximal end of the stent. The stent may be anchored within the body lumen by deforming or otherwise deploying anchor structures at either or both ends of the stent.
