摘要： A removable stent system and method for extraction of a removable stent from a target site is disclosed. The removable stent includes a removable stent having a collapsible end and a collapsing element configured for coupling with a removal tool. The collapsing element can be configured as a lasso or can be movable between two positions when deployed at a target site in vivo. The removable stent overcomes disadvantages and limitations of previous types of stents as well as overcoming complications during or following stent deployment in vivo. The removable stent further includes features that increase its ease of use and reduce the maneuvering required of devices or tools used to remove the stent. This then decreases the amount of effort required by the physician, the procedure time, and the level of discomfort experienced by a patient during the procedure.
